Studies have suggested that genes under strong sexual selection tend to evolve rapidly, particularly those associated with ...

Scientists discovered humans descended from two ancient populations, not one. These groups split 1.5 million years ago.

Let us tell you that the theory of evolution by natural selection was first formulated in Darwin's book "On the Origin of Species" in 1859. It is explained that organisms change over time as a ...

As conditions change, so does life. It evolves. Evolution is driven by a process called natural selection. And there's no better place to see how it works than in the forests of Madagascar.

THE author at the outset of this work tells us he “believes that the process of organic evolution has taken place, but he does not believe that natural selection has been the means by which that ...

Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes ...

They weren't at all certain that natural populations contained enough genetic variation for natural selection to create ... Simpson argued that the evolution of mammals, as seen in their ...

"Our history is far richer and more complex than we imagined," said human evolutionary geneticist Aylwyn Scally.

How are humans contributing to negative selection? It's a part of evolution that can also drive some species to extinction; models of negative selection help us understand biodiversity.

Natural selection is a mechanism of evolution—not evolution itself. "Natural" refers to how traits are passed on without intentional outside interference. (In contrast, "artificial selection" is ...

While Silicon Valley dreams of sleek, uniform progress, India opts for a patchwork quilt stitched together with hope, ...
