DNA mutation clock proves tough to set, of course fully expected by us

As reported by the latest issue of Nature (DNA mutation clock proves tough to set), the dates calculated so far for the Out of Africa model is really a joke. As a key player in the field David Reich says:“The fact that the clock is so uncertain is very problematic for us,” he says. “It means that the dates we get out of genetics are really quite embarrassingly bad and uncertain.”

The author says: "A slower molecular clock worked well to harmonize genetic and archaeological estimates for dates of key events in human evolution, such as migrations out of Africa and around the rest of the world. But calculations using the slow clock gave nonsensical results when extended further back in time — positing, for example, that the most recent common ancestor of apes and monkeys could have encountered dinosaurs."

Of course, we have said repeatedly in numerous papers since 2008 that the mutation rate should not be calculated by using genetic distances that are really maximum distance.

Again, without a real understanding , or with a mistaken understanding, of the first result in molecular evolution, the genetic equidistance result, the field really has no clue about what they are doing.
