Summary

On today’s ID the Future, Casey Luskin rebuts the oft-repeated claim that the human and chimp genomes are 98-99% similar and therefore surely resulted from Darwinian common descent. Luskin cites an article in the journal Science which describes the 98-99% claim as a myth. The original figure was derived from a single protein-to-protein comparison, but once you compare the entire genomes, and use more rigorous methods, the similarity drops several percentage points, and on one account, down into the mid-80s. Additionally, the chimp genomes used in the original comparison studies borrowed the human genome for scaffolding, thus artificially boosting the degree of similarity. What about supposed junk DNA similarities between human and chimp? Why would an intelligent designer put the Read More ›

0:00.0	I d the future a podcast about evolution and intelligent design.
0:12.0	Welcome to I. The Future. I'm Eric Anderson and joining us again today is Dr.
0:16.4	Casey Luskin to discuss a brand new book he contributed to, Science and Faith in Dialogue,
0:21.5	part of the Reformed Theology and Africa series.
0:25.0	Dr. Luskin is Associate Director at the Center for Science and Culture at Discovery Institute.
0:29.6	He holds a law degree from the University of San Diego, bachelor's and master's degrees in Earth Sciences, and a piece of it. a for having me Eric? So last time we got into the details of the fossil
0:44.2	record of hominins and we learned that the fossil record doesn't really
0:47.7	support a transition from ape-like creatures to humans. To summarize what you
0:52.0	noted at the end of the discussion we said we've got
0:54.1	ape-like fossils we have human-like fossils but not a good set of
0:58.2	transitional fossils documenting how one group evolved into another and that several researchers as you wrote in your
1:04.0	chapter have acknowledged the genus Homo came about an explosion or abrupt
1:08.8	appearance or rapid increase in features. So today I want to discuss another claim about human
1:14.2	evolution, the claim that humans and chimps share 98 or 99% of their DNA, you quoted
1:21.2	science popularizer Bill Nye who said,
1:23.5	as our understanding of DNA has increased,
1:26.8	we've come to understand that we share around 98.8% of our gene sequence
1:31.5	with chimpanzees. This is striking evidence for chimps and chumps to have a common
1:36.4	ancestor. So Casey, is Bill Nye alone? How common is this claim about our common ancestry
1:41.2	based on DNA?
1:42.2	Oh, I think we've all heard this claim that we're only maybe 1 to 2 percent different genetically
1:47.3	from a chimpanzee and therefore this is evidence of our close evolutionary relationship. It's almost ubiquitous. You can't go through the world
