Natural selection is the process by which some organisms in a population survive and reproduce, while others do not, based on their bodies and behaviour. It is one of the processes by which ...

The smaller-beaked birds couldn't do this, so they died of starvation ... The Grants had documented natural selection in action. While beak size is clearly related to feeding strategies, it ...

Natural selection, genetic drift and gene flow do not act in isolation, so we must consider how the interplay among these mechanisms influences evolutionary trajectories in natural populations.

Q: What do you think is the most widely misunderstood aspect of natural selection? A: I think the mistake that many people make about natural selection is thinking that since it's inexorable ...

Darwin visited four continents on the ship HMS Beagle. Darwin’s theory of evolution by natural selection challenged the idea that God made all the animals and plants that live on Earth.

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 ...

To constitute natural selection, the difference in survival and/or reproduction cannot be due to chance, and it must have the potential consequence of altering the proportions of the different ...
