[thechat] Journey of Man

[Daniel Wood]

There is a good book called "the seven daughters of eve" which is written by
the guy who discovered mitochondrial DNA.

f=sr_1_2_1/026-5000293-3123646

in it he describes tests he's performed on numerous peoples around the world
and what he's discovered about there origins. That people in south America
originated from people crossing over from Asia during the ice age, and the
other migrations of people around the world.

There's mitochondrial DNA, it's only passed on by the mother. There was
a BBC Television Horizon programme on super-volcanoes, broadcast a
couple of weeks ago, that described the technique of tracking
mitochondrial DNA as a means of estimating global population just after
the Toba eruption, 74,000 years ago.
