The latest episode of ID the Future discusses a recent (March 2012) paper about the gorilla genome.
On this episode of ID The Future, Casey Luskin discusses how the recent complete sequencing of the gorilla genome has challenged conventional thinking about human ancestry and explains what neo-Darwinists are doing to try to minimize the impact of this new information. Says Luskin: “There is not a clear signal of ancestral relationships that is coming out of the gorilla genome once you add it into the mix.” Tune in to hear about this interesting development!
Rather than summarize this short 10-minute podcast, I wanted to excerpt a post of Evolution News about it.

A whopping 30% of the gorilla genome — amounting to hundreds of millions of base pairs of gorilla DNA — contradicts the standard supposed evolutionary phylogeny of great apes and humans. That’s the big news revealed last week with the publication of the sequence of the full gorilla genome. But there’s a lot more to this story.
Eugenie Scott once taught us that when some evolutionary scientist claims some discovery “sheds light” on some aspect of evolution, we might suspect that’s evolution-speak for ‘this find really messed up our evolutionary theory.’ That seems to be the case here. Aylwyn Scally, the lead author of the gorilla genome report, was quoted saying, “The gorilla genome is important because it sheds light on the time when our ancestors diverged from our closest evolutionary cousins around six to 10 million years ago.” NPR titled its story similarly: “Gorilla Genome Sheds Light On Human Evolution.” What evolutionary hypothesis did the gorilla genome mess up?
The standard evolutionary phylogeny of primates holds that humans and chimps are more closely related to one-another than to other great apes like gorillas. In practice, all that really means is that when we sequence human, chimp, and gorilla genes, human and chimp genes have a DNA sequence that is more similar to one-another’s genes than to the gorilla’s genes. But huge portions of the gorilla genome contradict that nice, neat tidy phylogeny. That’s because these gorilla genes are more similar to the human or chimp version than the human or chimp versions are to one-another. In fact, it seems that some 30% of the gorilla genome contradicts the standard primate phylogeny in this manner.
The Evolution News post then cites New Scientist and Nature’s comments on the study.
