Quote: Selection is "widely ignored"

Tue, 2007-08-28 12:00 -- John Hawks

From p. xviii-xix of the preface of Selection, by Graham Bell (Chapman and Hall, New York, 1997):

One might expect, for example, that in Britain, the cradle of evolutionary biology, natural selection might be accorded an honored and conspicuous position. But in the published curricula of the programs that students follow preparatory to the university, it is no more prominent than aquaculture....

The treatment of selection in textbooks usually follows more or less the same course. There is an introductory section on genetics, sometimes even outlining the chemical structure of DNA, followed by an account of Hardy-Weinberg equilibrium, a page or two of population genetics, and of course the history of the peppered moth. The whole is illustrated by a picture of Darwin, looking stern, as well he might. This is a caricature, of course, but by no means an unrecognizable one. Thousands of students have left courses on evolution with the vague impression that selection is something to do with the Hardy-Weinberg law, and study for the examination by trying to remember which it is that adenine pairs with.

Neandertals

For years, I've worked on their bones. Now I'm working on their genes. Read more about the science studying these ancient people.

Denisova

From a finger bone of an ancient human came the record of a completely unexpected population. My lab is working on the science of the Denisova genome.

Acceleration

The advent of agriculture caused natural selection to speed up greatly in humans. We're uncovering some of the ways that populations have rapidly changed during the last 10,000 years.

Malapa

Just outside Johannesburg, the Malapa site is producing some of the most exciting finds in human evolution. This site is the headquarters of the Malapa Soft Tissue Project.
