The Comb Jelly

Now that it is beginning to look like Earth's first animal was much more complex and sophisticated than originally predicted, perhaps we should begin familiarizing ourselves with this amazing animal. Enjoy.

Out of curiosity – how does one define 'first animal'? I mean, what was the precursor to this thing, if it was in fact what scientists are now saying it is?

Precursor? If it is indeed the most basal lineage, then the precursors would be single-celled protozoa.

This observation is mind boggling. To my untrained eye the gap between single-celled protozoa and comb jellies is as big as the gap between comb jellies and science professors.

It's as if we eliminated the entire fossil record in one swoop and we are now supposed to imagine a pathway from Ctenophora to MAMMALIA with no fossil evidence at all.

fifth monarchy man: It's as if we eliminated the entire fossil record in one swoop and we are now supposed to imagine a pathway from Ctenophora to MAMMALIA with no fossil evidence at all.

There is very little fossil evidence from these early transitions. However, mammalia did not evolve from ctenophora, but from bilateria. They share a common ancestor in some more primitive metazoa, with ctenophores as the "earliest diverging extant multicellular animals." Porferia diverged later, along with Cnidaria.

Dunn et. al: The placement of ctenophores (comb jellies) as the sister group to all other sampled metazoans is strongly supported in all our analyses.

Sister. Not mother.

fifth monarchy man: To my untrained eye the gap between single-celled protozoa and comb jellies is as big as the gap between comb jellies and science professors.

Urmetazoa may have been a community of related cells. There is evidence that suggests that they had developed primitive communication (via tyrosine kinases) and other features that would later evolve into animals. So, yes. There is a very substantial evolutionary gap between the advent of eukaryotes and metazoa.

Hi All,

Time for me to drag out my favorite bilateria, the Vernanimalcula guizhouena.

They were running around 600 million year ago (pre-Cambrian).

Here is the link to my original comment on them.

The significance of this creature is that in was complex enough that it had a lot of the basics (e.g. four of the five senses).

I would like to provoke thinking, or at least discussion/argument, as to the relationship between Vernanimalcula guizhouena and Comb jellies.

It may actually be bigger. I would expect that many will try to disonfirm this finding, thus we'll have to see how it plays out.

Hi TP,

Well, I have a few minutes before running off. The body plan of the comb jelly is poised to reach the Vernanimalcula stage in two very significant ways "“ the origin of the bilateral plan and the origin of the mesoderm.

You are right to make this critter you favorite bilateria. Here's a schematic of its body plan:

From a front-loading perspective, it looks like the fundamental blueprint for every animal. In other words, if the front-loaded state could reach this stage, the rest is downhill.

Except for those that are not. For instance, ctenophores are diploblastic, have only a single digestive opening, differentiated tissues but no organs, and no coelum.

After all, humans are 'just' elaborated deuterostomes. A tube with appendages to stuff food into one end. Microevolution.

Interesting choice of words by Mike:

From the link:

The presence of the relatively complex comb jelly at the base of the tree of life suggests that the first animal was probably more complex than previously believed, says Dunn.

Slightly misleading, isn't it? Just as it is slightly misleading to suggest that the "first animal" was as complex as a contemporary comb jelly.

Quoting from the link:

How long ago did the earliest comb jelly diverge" "Unfortunately, we don't have fossils of the oldest comb jelly," laments Dunn. "Therefore, there is no way to date the earliest jelly and determine when it diverged."

Note the inherent vagueness to data relevant to an analysis. A critical juncture point at which one could assess front loading complexity vs. non-front loading would be the time scale allotted to the process. As long as there is no effective way of pinning down a reasonable time range our knowledge of mutations and other factors inducing change is of little value. However, there is a theoretical point at which evidence of radical evolutionary changes would not fit a too small time frame. That is the juncture at which front loading would offer a useful differentiating paradigm.

That doesn't make sense at all. I thought the FL allegedly happened before the multicellular stage, and that standard evolutionary processes took over from there, the outcome (primitive multicellularity and beyond) being very predictable for Teh Frontloader. Thus, if the time frame would be too small for evolution, so it would be for FL.

You didn't but if you are going to find data that distinguishes between two explanations- one of which is based on a concept of facilitated evolution made possible by cellular constructs lending foresight and the other explanation based on evolution, as depicted by the blind watchmaker, then time frames can be critical. A front loaded starting point can allow quick traversing of time constraints the blind watchmaker would have to grope his way through.

In light of the new information how do you know that there is a more primitive metazoa?

Urmetazoa may have been a community of related cells.

or it may have been a more complex animal than todays ctenophora the point is how do we know given the latest information.

We simply have no way to know the complexity of Urmetazoa and we have no way of estimating it as far as I can tell. It might be more or it might be less complex than ctenophora as far as we know.

I don't think you quite understand how big a deal this is.

The headline in EurekAlert is misleading. Your statement makes no sense in light of the actual scientific paper.

Dunn et al: The placement of ctenophores (comb jellies) as the sister group to all other sampled metazoans is strongly supported in all our analyses.

It's all about Common Descent. Ctenophores branched before porifera. Branched from what?

Dunn et al: In addition, we find strong support for several new hypotheses… the placement of ctenophores as the earliest diverging extant multicellular animals.

Note the word "extant". What Dunn et al. are doing is using molecular data from extant organisms and arranging them in the most parsimonious cladogram. (There are a variety of statistical means to determine if the inference is strong or weak.)

Here's a snippet of the cladogram showing the relevant portion. You will see that ctenophora branches off first, the other branch later diverging into bilateria and cnidaria and porifera. Once you understand Common Descent, you will see why it is considered such a powerful theory. Hope that helps.

One way of viewing front loading is to think of it as a series of set-ups. Evolutionary result z was made possible by both a process and the fact that genomic precursor x came loaded with what was required to enable outcome z. If the time lapse between outcome z and precursor x were found to be surprisingly short, i.e. inadaquate by conventional reckoning, a front loading perspective could predict what genomic properties to look for in precursor x.

It's all about Common Descent. You will see that ctenophora branches off first, the other branch later diverging into bilateria and cnidaria and porifera.

And your point is? Common Decent tells us nothing about complexity. Its ovious ctenophore is more not less complex than porifera. If that is the case for early life forms we know How do we know that the trend does not hold for their common ancestor as well?

My initial comment noted the inherent vagueness of relevant data including an inability "to date the earliest jelly." Given the great uncertainty as to what actually took place in deep time, an FL perspective could play a deciding role. It is difficult, if not impossible, to assess if "evolution happened too fast" when we are short on even basic information needed to estimate time and fix events.

Zachriel: Ctenophores branched before porifera. Branched from what?

fifth monarchy man: I don't know and neither do you.

Yet, we have every reason to believe that it did branch, and some idea as to the characteristics of the common ancestor. Common Descent is strongly supported, and there is significant evidence that this continues to apply to the earliest branches of metazoa. Furthermore, you're citing the conclusions of a paper based on Common Descent to support your argument!

Let's back up a bit and find out why I took issue with your previous statements.

fifth monarchy man: we are now supposed to imagine a pathway from Ctenophora to MAMMALIA with no fossil evidence at all.

This misstates the evidence. Mammals did not evolve from ctenophores. They share a common metazoan ancestor.

fifth monarchy man: In light of the new information how do you know that there is a more primitive metazoa?

Because the evidence strongly supports Common Descent rooted long before metazoa.

fifth monarchy man: All we know is that the older does not necessarily mean simpler even in deep time.

Of course not. You also seem to be conflating "primitive" with "complex".

fifth monarchy man: And your point is?

My point was that you were attempting to reason from a faulty understanding of the facts.

fifth monarchy man: Common Decent tells us nothing about complexity. Its ovious ctenophore is more not less complex than porifera. If that is the case for early life forms we know How do we know that the trend does not hold for their common ancestor as well?

Evolution isn't posited to follow a straight line. However, there is clearly a trend towards greater organization in metazoa. But you have to look at all the evidence to see that.

You are priceless

Furthermore, you're citing the conclusions of a paper based on Common Descent to support your argument!

Let me say it again so you can read my lips I don't dispute common decent. My point is that to affirm common decent says nothing about the complexity of the last common ancestor.

Mammals did not evolve from ctenophores. They share a common metazoan ancestor.

I was not claiming that mammals evolved from ctenophores only that there was a greater complexity gap between mammals and ctenophores than between ctenophores and protozoa.

Because the evidence strongly supports Common Descent rooted long before metazoa.

I agree but the evidence says nothing about the complexity of the last common ancestor. Are you really this dense or am I just not making my self clear?

Evolution isn't posited to follow a straight line. However, there is clearly a trend towards greater organization in metazoa. But you have to look at all the evidence to see that.

I'm not disputing that. I'm only stating the fact that we have no way of knowing the complexity of the Urmetazoa.

Sometimes dialogue with you is like pulling teeth.

If you don't dispute Common Descent, then you wouldn't ask whether there was a "more primitive metazoa", a common ancestor of mammalia and ctenophora.

fifth monarchy man: the evidence says nothing about the complexity of the last common ancestor.

Though we can't be sure about the specific organisms involved, we do see a general trend towards greater complexity over the period in question. There is also substantial evidence as to how metazoa evolved, and this evidence includes mechanisms (e.g. via tyrosine kinases) that stretch back far before metazoa evolved.

Hi kornbelt888! Excuse me just a moment.

…… Aargh!!!!

Anyway, as you are late to the discussion, ctenophores are not ancestral to mammals. This is supported by Dunn et al, the paper MikeGene cited above.

But questioning the processes of evolutionary change does not necessarily mean rejecting Common Descent. There are a variety of known mechanisms, and in many respects, it is the fact of common descent that we are trying to explain.

I belabor the point because Common Descent is certainly germane to the paper under discussion.

Perhaps. Let's take another look.

Zachriel: mammalia did not evolve from ctenophora, but from bilateria. They share a common ancestor in some more primitive metazoa,

fifth monarchy man: In light of the new information how do you know that there is a more primitive metazoa?

Nearly all scientists, including Dunn et al., agree that metazoa is monophyletic (from a variety of data, including microbiological and molecular evidence). That means that the most recent common ancestor of any two metazoans is also a metazoan. Ctenophora and bilateria are certainly both metazoan, so their most recent common ancestor is metazoan.

Maybe you're confusing "primitive" with being less complex.

primitive
1 a: not derived.
2 a: of or relating to the earliest age or period : primeval.
b: closely approximating an early ancestral type.
c: belonging to or characteristic of an early stage of development.

Primitive does not necessarily mean less complex. Indeed, a cobbled together mechanism may become simplified and irreducible through a process of optimization. Consider which has the more complex respiratory system, an air-breathing reptile, or its air-breathing and water-breathing ancestor lungfish. Or even a common frog that breathes with its lungs and through its skin. The answer is not so simple.

Do you agree that given the new findings we have just as much evidence to believe that the base of the tree is more complex than its first branch as we have to believe it's simpler?

Complexity can be difficult to quantify. We do see a general trend towards integrative complexity over the history of life. By most definitions, ctenophora is not as complex as vertebrates. But evolution doesn't have a goal, so complexity may wax and wane in different lineages.

fifth monarchy man: Do you think a comb jelly is cobbled together as compared to a sponge?

We would normally think of the comb jelly as more tightly integrated than the sponge.

Zachriel,

That's what I thought you meant.

Umm, no it's not! You may want to look 3 posts earlier to see what you actually thought I meant. LOL! (side note: selective memory is a scientifically supported clear indicator of prejudice)

As I am not a philosophical naturalist…

Never said you were, because that is something different. I said you were selling scientism. (And scientism accessories.)

…and as I have often disputed (on the appropriate forums) those who claim scientism as the only legitimate philosophy, I'm not sure why you would say I peddle that particular brand of bland, gray metaphysics.

Peddling scientism, and scientism accessories, does not entail that it is the only legitimate philosophy. You are twisting and turning, but I have yet to see you refute scientism in any way. Jeez, a couple of months ago you flat out refused to entertain a hypothetical question about ID, on scientismic grounds.

I'd love it if you prove me wrong on this, and I'll freely admit that I misjudged you. But so far it seems like when TT'ers say: (paraphrasing)

"ID is not science, but the suspicion may be valid"

you say:

"ID is not valid because it is not science"

In other words, you are peddling scientism to people who's suspicions transcend your opinion, and who have no use for your bland metaphysics.

However, the ID Movement has used false claims of scientific support to influence laypersons to effect political and social change.

Fingerpointing is the most primitive form of logical fallacy.

And do you really think that "The ID Movement" that you think you are attacking is to be found at Telic Thoughts? LOL!

If by posting Discovery Channel quality scientism you were hoping to interrupt a meeting of "The ID Movement", I'm afraid you've simply wandered into the internet equivalent of a Starbucks. Grab a mocha decaf and be quiet for a minute and you might actually be able to see the world from an ID'ers point of view.

Yeah, well, so what. Evidence certainly exists that lead A) leads many to wonder, and B) comports with many peoples' intution, philosophical, and religious views.

In the end, the cultural significance is "what it's really all about." I don't agree with some of the DI's agenda, but I certainly agree with them getting the evidentiary word out about certain features of the universe, the solar system, earth, and the nature of cellular mechanisms. For example, the "fine tuning" viewpoint of the universe may not be "science", but science isn't the end all be all to a lot of people. Probably most people. A lot of people have intuitions about such things, thank you very much, and are happy to deal with the evidence on that basis until something better comes along.

That's the point. If the "ID movement" is as pernicious as critics would have us believe then there should be evidence of it. When pressed critics invariably go to the archives and dredge up things like the dreaded Wedge document or the Dover PA case.

Come on baby, and do the twist. o/~

Speaking as someone who is closer to the TEs than the ID proponents in philosophy, I have to say – the worst scientific excess I see out of the ID movement (assuming 'movement' is 'the main and popular sites they run, and their more prominent speakers') is arguing that the known science leads to certain philosophical conclusions. Which I'd be upset at, except it comes on the heels of decades of the same from other, typically opposing, schools of thought.

Otherwise, most of what I see the "ID Movement" doing is highlighting developments in mainstream science, arguing against any erroneous philosophy they see inserted into a given discovery or press release, or arguing about how said discovery could support a philosophical view they enjoy. In other words, "Same crap, different viewpoint".

They do far more than that. They make sweeping *scientific* claims that the Theory of Evolution has been debunked or is fraudulent, and that they can scientifically detect design in biology.

Dembski: Materialistic ideology has subverted the study of biological and cosmological origins so that the actual content of these sciences has become corrupted… At the same time, intelligent design (ID) offers a promising scientific alternative to materialistic theories of biological and cosmological evolution

Behe: The theory of undirected evolution is already dead, but the work of science continues.

Not at all. Your own cite merely reaffirms the lack of new ID contributions to science. The claim that evolutionary biology is corrupt and that ID is a valid scientific alternative is a false claim. That these claims are being made by important voices in the ID Movement is supported above.

How is it harmful? The erosion of science and scientific thought could, in theory, significantly impact the economy of our nation. There is a lot of money to be made through application of scientific advancement be it increased crop yield, new energy sources, new materials, or advanced medical treatments. There is fierce international competition to develop new products based on new research, and by some estimates the US is starting to fall behind and lose our once dominate position as a science and technology leader. The ID sub-group that claims science is a corrupt "big-business" that only cares about money is at least correct that there is a huge financial impact from science.

Beyond that, scientific reasoning and critical thinking are valuable skills for many other high paying professions. In my opinion the intentional confusion sewn by the DI ID crowd and the foisting of superstition as if it were science weakens these skills in some people. If this leads to high paying jobs moving over seas then it will hurt our entire economy from top to bottom.

We have defined the term ID Movement as 'the main and popular sites they run, and their more prominent speakers'. I am not wed to the term, though. My statement was in the context of chunkdz's ill-defined claim about "scientism", and concerned why I defend valid scientific assertions. I'll restate more simply.

The claim that Intelligent Design is a valid scientific theory is false, and those that use this false claim to effect political and social change are wrong to do so.

Zach,

They do far more than that. They make sweeping *scientific* claims that the Theory of Evolution has been debunked or is fraudulent, and that they can scientifically detect design in biology.

As for detecting design – I have to say, so what? Stenger, Dawkins, etc and far more have been passing off philosophical claims as science for quite a long time prior. In my ideal world, science is science and philosophy/theology is philosophy/theology. In the world I live in, ID proponents are just doing what their (religion-hostile) predecessors have done. I have trouble getting too worked up over this, even though I try to maintain and advocate a sharp and reasonable dividing line.

Regarding the ToE, that's the funny thing – go to Allen MacNeill, who is himself pretty hostile to ID by any measure, and he'll quite happily admit that there have been major changes and developments in how we view evolution and ToE, even in the past few decades (Unless I read him wrong, so by all means Allen, c'mon over and correct me if you please. But I think I'm being fair here.) Hell, the "RM+NS = Evolution" explanation is such a gross oversimplification that calling it fraudulent is more correct than incorrect.

And before I hear it – yes, I know 'the basic understanding hasn't changed' – but the basic understanding was ludicrously simple anyway. If aliens periodically come to earth and intervene to promote certain traits over others, 'the basic understanding hasn't changed'. Yes, I'm sure there are some ID proponents who have either simplistic or flat-out incorrect views of the science – but then again, I've encountered ID-opponents with a grossly simplistic, incorrect view of ToE as well. By and large what I see most often are philosophically/theologically motivated people poring over the science news RSS feeds for news they can jump on and interpret according to their preference. If you want me to believe that's an ID-exclusive sin, sorry, I hang out at one too many religion-intolerant forums to swallow that line.

"Tons of people on all sides" in my experience. I'm not sure if it's a strawman when it's what amounts to the de facto popularized understanding of ToE. You may as well call gene-centric views of evolution a strawman as well, just because it's a mere model rather than a penultimate view of science. But blaming many ID proponents for attacking such a view would be, I don't know. Really funny, I suppose.

Yes, Zach, get that catch-phrase in there for the thousandth time, so it can get ignored for the trash it is the thousandth time. And the ID (or even TE) proponents will shoot back that the whole concept of development according to natural laws was thought up by theists who saw God as rational, ergo every success of science owes a debt to religious motivation. You'll see me a Galileo and raise me a Giordano Bruno, I'll check-raise you Gregor Mendel and William of Ockham and more, and it'll go on until a more interesting fight breaks out on TT, probably right beneath an otherwise innocuous picture of a bunny. There, we've done the dance and saved each other time. Science!

I happen to love the ToE myself, so praise it all you want. The principles contained therein can be used to outstanding effect by an intelligent agent – it's leading to some wonderful concepts in software design and otherwise. Kind of amazing what evolution can accomplish for an intelligent force, isn't it?

You are part of the same dynamics you criticize. If the DI's position is your problem then this all amounts to "I disagree with them." That's the gist of the movement complaints. The DI does not agree with you.

Bradford: Todd, do you realize that you are a part of a movement by the standards you describe in this thread?

Yes, absolutely. I am proud to declare my affiliation with secular movements and would never attempt to hide such affiliations in order to obfuscate my biases.

Bradford: Do you then realize how banal your "ID movement" charges are?

I don't see this as a "charge", merely a classification. If you can provide some better or more accurate classification then please do. I mean, I could use some other term like "cdesign proponentsists" but that seems truly banal to me. In other words, I think the phrase is often repeated simply because it is a meaningful classification.

Bradford: If the DI's position is your problem then this all amounts to "I disagree with them." That's the gist of the movement complaints. The DI does not agree with you.

I have already stated that I disagree with the DI and of course I would prefer to see my views win out over theirs. So sure, that's undoubtedly a factor. But then they go about making blatantly false claims in order to trick people into agreeing with them so we get to have fun proving they are false . If opinion is stated as fact then it is right to point out that error. If bias is treated as evidence it is right to point out that error. If evidence is exaggerated it is right to point out that error. But if opinion is stated as opinion, while it would be an error to simply call that opinion wrong, it is acceptable to state an alternative opinion.

Be proud but at the same time do not be so foolish as to think you have made a point worth listening to when you decry the ID movement to a group of IDists. Should anyone care that you like your own movement and dislike those that disagree with it?:roll:

I jumped in to answer you question of why someone might think the ID movement is harmful. You asked for an opinion so I offered an opinion. I guess I should assume that whenever you ask for an opinion you don't really want a response?

I don't think you're getting this Todd. Your opinions as to what is harmful are unrelated to ID itself. They are socio-political in nature. Even an IDist who shares your views will not be persuaded because he or she knows IDists come in all varieties and what unites us is our views about Intelligent Design. If your intent is to persuade people you are doing nothing more than preaching to the choir.

Are you denying anyone holds this position or are you expecting my to formulate an exhaustive list of every view every person on earth holds? If you deny the position is held by anyone I might be willing to dig up a single example to show it does, but I will not waste my time cataloging people's beliefs. Since I make no claim whatsoever about the size or importance of this sub-group then unless you deny it's existence entirely there is nothing else to say.

ID as presented by the thought leaders of the movement is socio-political in nature. Even here where people are generally much more rational ID is presented as metaphysics. There is no science of ID. Since ID is nothing but opinions it seems that contrary opinions hold just as much significance to me. As I have mentioned many times you cannot disprove an opinion, even if you can disprove some of the assumptions that are used as a foundation for the opinion it ultimately comes to subjective assessments. Battles over metaphysics are always about both sides preaching to the choir, and yet that preaching does seem to have an effect over the long haul. I am not denying these issues, just pointing out they apply equally to all parties involved.

Wrong. Behe, Dembski et. al. sincerely believe in the ID views they put forth. The fact that you would characterize them as socio-political while ignoring the blatent socio-political ejaculations of a godless liberal and much more of that tripe speaks volumes. The socio-political comments in evidence here come primarily from ID critics- including you.

Todd B.,

"Are you denying anyone holds this position…?"

I'm sure some people hold that position. ALF certainly does, but I wouldn't consider them an "ID subgroup". Maybe the Raelians. Are they an "ID subgroup" I don't know.

My guess is that this is just some boogeyman you concocted to further confirm your bias against ID.

I am willing to accept for the sake of argument that they are not lying for Jesus but that they sincerely believe in the ID views they put forth. That does not make those views apolitical. The DI knows very much that this is a socio-political issue, just read their wedge strategy or look at their latest buzz-word, "denormalization." Even someone who is not political themselves is a part of this socio-political struggle if their works are used as ammunition for one side or the other. This might not be fair, but that's the way it is regardless. If you use the term "ID" you are part of the Culture War no matter how apolitical you try to claim you are.

Todd, all you're claiming, based on your arguments, is that prominent people on all sides have socio-political agendas. So the DI has their movement and you and PZ have your own. Comments like yours help others see the existence of an anti-ID movement and its desire to substitute red herrings for substantive discussions.

Sure, fair enough, but those comments also help others to see the existence of a pro-ID movement and its desire to substitute red herrings for science and rational thought. In this case statements of equal substance are being provided by both sides, metaphysical positions have been outlined. Honestly I hope that Mike's ideas have a strong impact on Joe Midwest ID supporters, apologists, and sympathizers. And by knowing that us Godless heathen types still find Mike's middle ground to be largely unsupported it might be easier for them to integrate Mike's more reasonable position with their various superstitious beliefs. I mean, if us godless heathen types supported Mike we'd scare off all the religious folk! So we have to point out these limitations in order increase their conviction in Mike's theory and steering them clear of the deeper abyss of ignorance they might otherwise fall into.

She doubted her faith, doubted the existence of God. You take that as meaning she believed there is no God and no substance to her faith?
Why?
For you does doubt mean denial?

She wasn't an atheist. She was a Catholic that struggled, add her to the ranks.

For you though it should be a non-factor. Her initial compulsion to the Catholic faith wasn't empirically based. It was one of those nonsensical spiritual experiences that would have meant nothing to you from the get-go. Why are you acting now like this is gained real estate?

Her initial attraction toward the faith was certainly not of the type that led Antony Flew to admit the existence of a Designer.

Just ignore Raevmo – he knows damn well Mother Teresa was a Catholic, but he's baiting. Just as he knows Stalin and Mao were atheists, and Madalyn Murray O'Hair proved that atheists can be duped by the equivalent of a televangelist just as easily as anyone in a super-church.

Hitler, the christianity-hater? Hell if I know what his faith (or lack) was. Sure liked eugenics though. Then again, so did a few of your idols – it was big back then. Part and parcel with those 'enlightenment values' I hear so much about.

Stalin 'outlawed Darwinism'? Him boosting his crony Lysenko hardly counts. But if you're trying to tell me that atheists can have a warped view of what constitutes science and truth, hell – I agree without reservation.

I am coming to this discussion late, and have only skimmed through the comments (especially the later ones), so maybe this has already been discussed. In the OP Mike says "Earth's first animal was much more complex and sophisticated than originally predicted". I do not understand how that can be inferred from the research. My reading is that a long time ago the primitive animals split into two groups, one of which gives us the comb jellies we see today (actually a phylum Ctenophora), the other group giving all the other species of animal in the world today. The comb jellies have had perhaps a billion years of evolution (the paper notes that they could not determine when the split happened, so this figure is merely my guess) in which to become the complex and sophisticated creatures we see today. Also, there may well have been another billion years (say) of evolution prior to that between the first animal and the split between the comb jellies and the rest of us.

Perhaps the first animal was extremely simple, evolved into a species that was fairly complex (as well as numerous species that have left no remains todays). That fairly complex species evolved into two new species (both fairly complex still), one of which was the ancestor of the very complex and sophisticated comb jellies, the other the ancestor of all the other very complex and sophisticated animal species around today.
