Hey Ben.
It's been a while since I was really "at" EvCForum, but I know people with the knowledge to help can certainly be found here!
Unfortunately the ranks have dwindled (or been thinned depending on your view).
... help deconstruct some of the technical methods behind this article?
Personally, I have a lot of trouble using genetic information - as relics of the past preserved in the present - to talk about
when certain changes/events/milestones occurred. To me they can talk about what happened, and the relative timing of different events, but not about absolute timescales.
Also see
BBC Human Evolution, "the New Batch":
quote:
At one point, the numbers of modern humans living in the world may have dwindled to as few as 10,000 people.
The genetic data puts the likely date for this event at just before 100,000 years ago.
This is essentially the same concept of bottleneck evidence in genetics, but they are talking about very different timing. If this is the same event and one set says 70k and the other 130k ...
Enjoy.
