Learning to fly is easy, if you are a bird. But why is it that birds learn so easily how to fly? It is well known that birds learn through practice, and that they gradually refine their innate…

A research team has found experimental evidence that supports a controversial theory of genetic conflict in the reproduction of those animals that support their developing offspring through a…

A new report from researchers at the University of Colorado and Stanford University speculates how unique, lineage-specific gene copy number expansions and contractions in humans may underlie traits…

The abundant diversity of characteristics within species likely helped fuel the proliferation and evolution of an odd-looking creature that emerged from an unprecedented explosion of life on Earth…

Early man was on a constant quest for food. The demands of nourishment and conserving as much energy as possible may even have changed the course of evolution. While no one has an authoritative…
