Body plan evolution not as simple as once believed

The role of Hox genes in changing the layout of different body parts during evolution has been challenged by a study led by researchers out of the University of Pittsburgh's Department of Biological Sciences.

Grazing animals drove domestication of grain crops

Many familiar grains today, like quinoa, amaranth, millets, hemp and buckwheat, have traits that indicate that they co-evolved for dispersion by large grazing mammals. During the Pleistocene, massive herds directed the ecology ...

Lunar and solar eclipses make animals do strange things

For most animals, the structure of their day—and indeed their year—depends on the light-dark cycle. These regular and rhythmic cycles in the length of days tell animals when they should be foraging, when they should be ...

Neutral evolution shapes lifespan and aging

Different African killifish species vary extensively in their lifespans—from just a few months to several years. Scientists from the Max Planck Institute for Biology of Ageing in Cologne investigated how different lifespans ...
