Investigating the signatures of natural selection can help elucidate the evolutionary adaptations that have allowed humans to withstand some of our most complex and challenging selective agents.

Natural selection implies that if organisms are surviving, they are adapted. But as the environment changes, we may find that what was once an adaptation may no longer be useful. Although it’s ...

Although the study of natural selection in humans is still in an early stage, the new data, building on decades of earlier work, are beginning to reveal some of the landscape of selection in our ...

Evolution is driven by a process called natural selection. And there's no better ... Which is fortunate for me, because she has certain adaptations that I wouldn't like to be deployed.

The proportion of well-adapted organisms in a population can increase over the generations by the process of evolution by natural selection.

Experts have been studying remote mountain communities and found they have certain genetic advantages which prove that ...

this is the essence of adaptation. “On the other hand ... the often overlooked flip-side of natural selection. Some variations are disadvantageous and will be culled. In fact, it is this ...

I am an evolutionary ecologist interested in contemporary natural selection and microevolution in wild animals ... so my lab is currently particularly interested in maternal effects and other social ...

Natural selection at its most powerful winnowed ... with bigger beaks. So the adaptation to a changed environment led to a larger-beaked finch population in the following generation.

I like to argue that adaptation is the engine that drives Mother Nature. In biology, adaptation is broken down into three different aspects. The first of the tri-aspects is that natural selection ...

These discoveries challenge the traditional thinking about natural selection, and imply that ... This could also help to speed up the process of adaptation, and may explain why species sometimes ...

How could something so complex, they argue, have developed through random mutations and natural selection, even over millions of years? If evolution occurs through gradations, the critics say ...
