And all I am saying from this bit:
quote: In addition, the rate of evolution has been far greater in the lineage leading to humans than in the lineage leading to macaques.
Is that this rate of evolution must have happened in the time during erectus and after A. afarensis . If I am wrong then please tell me during which period when most of the brain evolution took place ..
Well, you obviously can't say that from that bit since macaques are not Australopithicines. The research gives an average rate of mutation over the time period. What you've shown us with this study is that the average rate of mutation is "small" (i.e., a conserved mutation every few 1,000 generations). It doesn't say anything else.
I don't think anyone doubts that there were times of more rapid change within that time but that's NOT an issue with the study you posted.
Brain size may be something which can be "rapidly" increased by only a few mutations.
