Long before DNA unraveled the double helix of life, scientists were already tinkering with its inheritance. The idea that ...

"Regressive evolution," or the reduction of traits over time, is the result of either natural selection or genetic drift, according to a study on cavefish by researchers at New York University's ...

Evolution is a gradual change to the DNA of a species over many generations. It can occur by natural selection, when certain traits created by genetic mutations help an organism survive or reproduce.

that natural selection is not the only mechanism of evolution. And he grew exasperated with scientists who overlooked his point. Traits can evolve by genetic drift, for example, as no more than ...

But future research by geneticists provided the mechanism and additional evidence for evolution by natural selection Darwin chose the term "natural selection" to be in contrast with "artificial ...

it means that there are opposing forces at the heart of evolution. Complex structures and behaviour such as eyes and language are undoubtedly the product of natural selection. But when selection ...
