Gene mutation helped split humans and apes

AI Thread Summary
Researchers have discovered a significant gene, MYH16, which has a mutation that inactivated its role in developing jaw muscles for chewing and biting in modern humans. This mutation, found in all contemporary humans globally, is absent in other primates like chimpanzees and macaques, who possess strong jaw muscles due to an intact MYH16 gene. DNA analysis indicates that this mutation occurred between 2.1 million and 2.7 million years ago, likely around 2.4 million years ago, marking a pivotal evolutionary divergence between humans and other primates.

"The researchers' new discovery involves a gene called MYH16, which had apparently gone unrecognized because of a small mutation that had rendered it inactive for producing some jaw muscles for chewing and biting. The scientists found that this myosin gene was still intact today in other primates, like chimpanzees and macaques, which have correspondingly strong jaw muscles. An analysis of DNA samples showed the gene-inactivating mutation to be present in all modern humans worldwide. The analysis further traced the mutation's occurrence to a range of 2.1 million to 2.7 million years ago, probably 2.4 million."

:eek: really :redface:
I'm going to lock my own thread then.. who would've thought that'd ever happen :rolleyes:

thanks Ian :biggrin:

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...
