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 ...

Evolution is often depicted as a steady forward march from simple to complex forms. But new research shows that certain ferns ...

They have done nothing less than witness Darwin's theory of evolution unfold before their eyes. That would have stunned Darwin, who thought natural selection operated over vast periods of time and ...

In this scenario, the deleterious allele will remain at an intermediate equilibrium frequency that reflects the balance between gene flow and natural selection. The common conception of evolution ...

Over the years, the theory of evolution by natural selection has itself evolved, absorbing new findings about genes, DNA, population genetics and epigenetics, all of which weren't available in ...

We tend to think of evolution as a one-way process: simpler beings gradually advancing to become more sophisticated lifeforms ...

as determined by natural selection, within bacterial populations. While I consider myself an evolutionary biologist, over ...

As time goes by, the system will grow more diverse and complex, gaining the functions needed for survival, through a kind of ...

Imagine a photograph of your great-grandparents, grandparents and parents side by side. You’d see a resemblance, but each ...

A Perspective summarizes the risks of bypassing natural selection when using assisted reproductive technologies (ART) in ...

In our Centre for Evolution and Cancer, researchers apply Darwin’s principle of natural selection within ecosystems to ...

Natural selection, as introduced by Charles Darwin in the Origin of Species (1859), has always been a topic of great conceptual and empirical interest. This book puts Darwin's theory of evolution in ...
