The melanocortin region of the modern human genome has was studied by Makova
et al and shown to contain evidence that mankind has been an interbreeding
group for a very long time. Below is the table showing the 95% confidence
intervals for how long it would take modern diversity to arise (known as the
time to the most recent ancestor-TMRCA)

All examples lead to the probability that our common human ancestor is much
older than mitochondrial Eve and to the conclusion that our common ancestor
was not anatomically modern.
