Re: Recent Human Evolution
In fact there is evidence of evolution going at an accellerated pace in humans compared to other species -- due to sexual selection and\or due to pushing into\creating new environments.
​
Recent articles:
PLoS-Biology Journal, A Map of Recent Positive Selection in the Human Genome Showing evolution in three different branches
​
and
PLoS-Biology Journal, Clues to Our Past: Mining the Human Genome for Signs of Recent Selection a shorter, more readable review of the same information.
​
One interesting thought is that if we are the fastest evolvingin species, then how do we recognize "macro"evolution?

Re: Recent Human Evolution
... referencing exactly the same paper I was referencing in the first place.
​
oops. (throws out new glasses, gets old pair). My bad, just found it by other means and was looking for a thread to drop it on.
​
What comparable studies on other species were you thinking of?
​
I was also thinking about the study that showed an higher rate of evolution in humans than in chimpanzees. Of course if they used all the genetic differences in humans against all the ones in the chimps since divergence, then the data may be a little confused by the data from this study.
http://www.newsroom.ucr.edu/cgi-bin/display.cgi?id=875
"During the same amount of time, humans accumulated more genetic novelties than chimpanzees, making the human/chimpanzee genetic distance larger than that between the chimpanzee and gorilla."
​
This PLoS study does talk to increased pressure to evolve due to spreading into new environments and adapting to new (pathological) conditions.
