Through natural selection, different types of eyes have emerged in evolutionary history -- and the human eye isn't even the best one, from some standpoints. Because blood vessels run across the ...

Our eyes evolved through natural selection—but human ingenuity can perform wonders. With the aid of a retinal implant in his left eye, Peter Böhm can recover some of the sight he lost to the ...

The early part of the twentieth century saw evolutionary theory embattled by disagreements over Darwin's emphasis on natural selection ... of substantial change through rapid "quantum evolution ...

Eyes are so intricate, they say, that it stretches credibility to suggest they evolved through the selection and accumulation of random mutations. Those intermediate forms have now been found.

Today, with access to heretofore unprecedented data sets for the study of human genetic variation, researchers can exploit the genetic signatures of natural selection using novel analytical methods.
