Mutation-selection balance has long been used for animal populations, and Amorim says it can be applied to humans too. “Now we know that these assumptions are likely true,” says Amorim, ...

Groups with few mutations are amplified by selection but lose members to other groups by mutation. Groups with many mutations don't reproduce as much, but gain members by mutation. view more ...

This was in contradiction to R.A. Fisher's emphasis on one primary global peak which natural selection slowly ascended through action upon additive & independent genetic elements. Over the past 70 ...

For their model the scientists assumed a steady environment and suggest that there can be a mutation-selection balance in every population. They have calculated the rate of favourable mutations ...

If natural selection is weakened, mutations it would normally purge aren’t removed as efficiently, which could increase their frequency and so increase the rate of evolution.

Like the little boy who can't help sticking his finger into the socket, Dan MacArthur is talking about race, IQ & genetics again.He quotes an exchange in nature where a researcher states: So, given ...

Instead, the cheaters in each generation are likely the offspring of non-cheaters, but with mutations that made them non-cooperative ... Jander, K.C. and Steidinger, B.S. 2017. Why mutualist partners ...

Humans’ closest primate relatives lost their tails about 25 million years ago, but exactly how has remained a mystery. A breakthrough in genetic research may finally offer answers.
