Re: Recent Human Evolution
Given the relatively recent development of modern medecine it is far too early to say whether it will in any way reduce change in the human species, and certainly too early to say that it has, it may well affect it but it is premature to suggest we know how it will affect it.
At the moment there is no evidence of any peculiar degree of stasis in human DNA, in fact a recent paper in PLOS documented a number of loci which are distinct amongst different populations (Voight, et al., 2006).

Re: Recent Human Evolution
Recent articles:
PLoS-Biology Journal, A Map of Recent Positive Selection in the Human Genome Showing evolution in three different branches
I'm not quite sure why you replied to me referencing exactly the same paper I was referencing in the first place.
I'm also not sure that the paper supports your contention about an accelerated rate of evolutionover other species, certainly neither the paper nor the precis article seem to state this. What comparable studies on other species were you thinking of?
TTFN,
WK

Re: Recent Human Evolution
This PLoS study does talk to increased pressure to evolve due to spreading into new environments and adapting to new (pathological) conditions.
Its quite a leap from this to humans being the 'fastest evolving species'.
That diveregence research appears to be based solely upon the number of ALU repeat insertions. There are any number of other possible metrics which give quite different answers, for instance chimps have 300 new pseudogenes as opposed to 200 in humans since divergence.
TTFN,
WK
