closeWhich type is newly evolved?
Posted by Seokha_Kang on 03 May 2012 at 18:27 GMT
This research is very interesting. I wondered which one is a newly evolved character.
I performed phylogenetic analysis for 18 OR7D4 amino acid sequenced of primates including nine human sequences (one is WM, the others are RT). All of great apes have RT type but one of human is WM. This means that the WN type (insensitive) is newly evolved in human lineage.
I suspect the ignorant of bad smell had a selective advantage during human evolution by making an individual intake more meat.
The MP tree is available at my blog. http://evolbio.tistory.co...

The environmental change gave advantage for this mutation is hunting or pig domestication?

The evolution of OR7D4 in primates has been examined functionally here:
