Gene mutation helped split humans and apes

In summary, researchers have discovered a gene called MYH16 that is responsible for producing jaw muscles for chewing and biting. This gene is found in other primates like chimpanzees and macaques, but is inactive in modern humans due to a mutation that occurred 2.1 to 2.7 million years ago. This discovery sheds light on the split between humans and apes and has been published in the journal Nature.

"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:
 

1. What is gene mutation?

Gene mutation is a change in the DNA sequence of a gene, which can result in changes to the characteristics or traits of an organism.

2. How did gene mutation help split humans and apes?

Gene mutation can lead to the development of new traits or characteristics that can provide a selective advantage for an organism. In the case of humans and apes, gene mutations may have caused changes in physical and cognitive abilities that allowed for the split and divergence of the two species.

3. Are humans and apes still evolving through gene mutation?

Yes, humans and apes are still evolving through gene mutation. Gene mutations occur constantly and can lead to the development of new traits, which can then be passed down to future generations.

4. Can gene mutation also have negative effects?

Yes, gene mutation can have negative effects, such as causing genetic disorders or diseases. However, not all gene mutations are harmful and some may even provide a selective advantage for an organism.

5. Is gene mutation the only factor in the split between humans and apes?

No, gene mutation is not the only factor in the split between humans and apes. Other factors such as environmental changes and natural selection also played a role in the divergence of the two species.
