We’re all aware of the severe genetic and unpleasant physical consequences that result from reproducing with a closely related relative.  Aside from unfortunate aesthetics, inbreeding can also…

Bell curves are everywhere. Pick 100 random people and measure them: measure their height, their weight, their blood pressure, their time to run a mile, or to sprint 50 yards, and their IQ, and you…

I have always held a fascination for transposons, or jumping genes as they are sometimes called. Part of this interest may be due to my background in Drosophila genetics, where a transposon called a…

It makes sense that ecological changes caused by humans affect natural biodiversity and, in some cases, can even cause permanent displacement of a species. Unless science revives it. Researchers…

Polymorphisms are variations in genes which can result in changes in the way a particular gene functions and thus may be associated with susceptibility to common diseases. In a new study in…

You might think that predicting eye color is easy because we all learned in high school about recessive genes and eye color is a great example of those.    But it isn't easy.  In fact…

Researchers have discovered that a long-defunct gene was resurrected during the course of human evolution. This is believed to be the first evidence of a doomed gene – infection-fighting human IRGM…

A female moth selects a mate based on the scent of his pheromones. An analysis of the pheromones used by the European Corn Borer (ECB, Ostrinia nubilalis) shows that females can discern a male's…

Women can take pride that they are more efficient than men in many ways, including one that is not so great; storing fat. It's a paradox women have discussed for generations – their apparent ability…

Teams of scientists from Australia and the United States have used yeast and mammalian cells to discover a connection between genetic and environmental causes of Parkinson's disease.  Yeasts are…
