(PhysOrg.com) -- The brains of all vertebrates display gender-related differences. In songbirds, for example, the size of the brain areas that control their singing behaviour could be linked to the size of their song repertoires. ...

Maize is a staple crop that came from humble beginnings. If you look at its wild ancestor, teosinte, the plant looks nearly unrecognizable. Human selection has persuaded the maize plant to grow in a way that produces higher ...
