Dude…Where’d this weed come from?

Globalization and other human activities such as domestication can influence population structure of the earth’s flora and fauna, having broad implications for biodiversity.  For example, Cannabis sativa (a.k.a. hemp/marijuana) has been used by humans for diverse purposes including medicine, spirituality, entertainment, and as a source of fiber for thousands of years.  Because of its broad utility, this plant has been subject to extensive cultivation, artificial selection, and global trade.  As a result, the origins and historical patterns of genetic diversity of marijuana ...

From VT News:

Evolution can be both stimulated and halted by an animal’s behavior, it just depends which trait you’re talking about, according to a groundbreaking study led by a Virginia Tech researcher.

The study, published Oct. 25 in the journal American Naturalist, shows behavior can be both a brake and a motor for evolution in a manner where slowing evolution in one trait actually requires accelerating evolution in another, according to Martha ...
