One critique -
"Stanford University geneticist Peter A. Underhill is more critical of Templeton's approach. The number of people whose nuclear DNA sequences were analyzed in the new report was too small to provide convincing evidence, Underhill says.
No ancient gene sequences have been identified in living people that reflect their ancestors' interbreeding with Neandertals or any other extinct Homo species, the Stanford researcher says."
That's the problem with the Multiregional hypothesis, there's no evidence for it.
When did lack of evidence ever discourage an evolutionist?
