Populations sampled so far (all three recent studies focused mainly on Europeans and African-Americans) have had different patterns of diversity, shaking up population geneticists
' assumptions that one measure of diversity should fit all human groups.
Synonymous nucleotide changes (neutral mutations) are commonly used to estimate many values of interest to evolutionary biologists and population geneticists
This field may be less familiar to the authors than sociobiology, and there are some lapses in historical accuracy (e.g., population geneticists
will be surprised to read that "phenotypic plasticity in life history strategies ...
Perhaps, therefore, population geneticists
are the lucky ones in the evolutionary biology fold: at least, in Mendel, they know something that Darwin did not.
The researchers hope that this paper will serve as a template for other population geneticists
to conduct similar projects on human evolutionary history in the future.
According to a report in the New York Times, the estimate was made by a team of population geneticists
at the University of Utah led by Chad D.
It was a tide of rigorous mathematical thinking that brought the population geneticists
to supremacy over the old school of descriptive naturalists a generation ago, and it may be that the next wave will elevate the computer modelers, with their messages from the school of chaos theory.
Other population geneticists
have reached a similar conclusion by examining the genes in the parasite's mitochondria.
Mayr's embrace of genetic coadaptation and organismal integration, with peripatric speciation by genetic revolution its dearest offspring, is fundamental to his stormy relations with population geneticists
. It would be a mistake to think he entirely disparages mathematical theory: he drew on theoreticians' work in both the 1942 and especially the 1963 books, and has continued to do so since (e.g., 1988, pp.
Cholera does not seem to have reached Europe until the 1800s, too late to explain the high frequency of the mutant cftr gene, say population geneticists
For decades, the red wolf has been nearly indistinguishable genetically from either the gray wolf or the coyote, report two population geneticists
who have compared DNA "fingerprints" from captive red wolves with those from frozen blood samples and museum skins.
