Re: Traces of a bottleneck in the history of the European population

"In this case, we
ask the basic question why the author is looking at only europeans,
as we should wonder if his conclusion that other population
structures and interactions with his population are meaningless, or
simply the next paper on the subject. "

This was one of the things, among many, that puzzled me, why just
Europeans.
For another, let me quote Jobling, et. al., p. 182: "The TMRCA of
a set of alleles is typically much older than the population in which
they are found" Example given is the colony on Mars. "Only when
there is a strong bottleneck or founder effect is the TMRCA similar to
the age o;f the population." And they explain how to determine
population expansion from a mismatch distribution, though are rather
vague as to how to see it is a bottleneck, except there is a loss of
haplotypes from the parent population.
This paper seems to be saying they have a TMRCA much greater than
the time of the bottleneck.

" The other 1/2
male is going to have to find his own history, :^)."

Does he get to keep one testicle?

"Recombination can have the effect of increasing effective
ploidy, and
sites that are recombinant may appear to be older than they actually
are since conversion and recombination can result in the more rpaid
mutation appearance coming out of diverse population,"

Which was why he picked LD sites, nicht wahr?

"but in from central africa
into the sahara, a road erased by later migrations into the region
and by climate change. "

How did they get into Europe and Asia then, along the littoral?

Ok, guess I got the rest of it.
