Many scientists have assumed that our hands evolved their distinctive proportions over millions of years of recent evolution.
Chapter 4, "The Perfect Paleofantasy Diet: Milk", explores one of the best examples of recent evolution in humans – the ability to digest lactose.
You will find examples of recent evolution in humans and other organisms, with a level of detail satisfying for scientists but not overwhelming for novices.
The work, presented here last week at the 84th annual meeting of the American Association of Physical Anthropologists, offers dramatic evidence of recent evolution in Europe and shows that most modern Europeans don't look much like those of 8000 years ago.
He cites, as an example of recent evolution, the steep decline in the frequency of the gene for sickle-cell anemia among African-Americans, compared with what you'd expect to find, given the percentage of their African ancestry and the prevalence of the gene in Africa.
PCSK9 is only found in vertebrates, suggesting it is the product of recent evolution [27].
However, the lack of knowledge of recent evolution of each H1N1 viral gene segment precludes the use of this approach to determine viral origins.
However additional analyses among nuclear rDNA genes will be necessary to confirm the hypothesis of recent evolution and identification or delineation at to species of the genus Hyas.
Some recent molecular phylogenetic and genomic results on the two components of the CD genome are difficult to integrate to our scenario of recent evolution, unless the two genomes have very different rates of evolution.
Taken together, our results indicate that pBRP2s define a plant-specific TFIIB-related protein subfamily and suggest that their distribution is restricted to members of the Brassicacea family, a sign of recent evolution in the history of land plants.
