Creationist sites were abuzz today over a recent paper in Nature. For example, Fazale of "Reasons To Believe" wrote this:
During the opening day’s plenary session, biologist Darrel Falk, president of the BioLogos Foundation, presented a case for evolutionary creationism (formerly known as theistic evolution). Specifically, Dr. Falk argued that humans and chimpanzees must have evolved from a common ancestor because of the Alu sequences found in human and chimpanzee genomes…
Some mRNA molecules possess Alu sequences near one of the molecule’s ends. These Alu sequences can pair with Alu sequences in lncRNAs to form a duplex with the two RNA molecules. This duplex is targeted by a protein called STAU1, which binds to RNA duplexes and destroys them. As a consequence of this destruction, protein production is kept in balance.
Discoveries like this one undermine the case for common descent and human evolution made by evolutionary creationists like Falk.
I honestly don't see the connection. Forgetting for the moment that STAU1 doesn't actually do the destruction, how does this account for the differences? Evolution has occurred since humans and chimps (and other primates) diverged, which actually does explain those differences.
