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 Grants had documented natural selection in action. While beak size is clearly related to feeding strategies, it is also related to reproduction. Female finches tend to mate with males that ...

Q: Tell us about this "dangerous idea" of Darwin's. A: I think Darwin's idea of natural selection is the best idea anybody ever had, ahead of Newton, ahead of Einstein. What it does is it promises ...

Aa Aa Aa Natural selection, genetic drift, and gene flow are the mechanisms that cause changes in allele frequencies over time. When one or more of these forces are acting in a population ...

The phrase "survival of the fittest" functions principally in evolutionary theory to describe the biological concept of ...

By analyzing data from three generations of Americans, researchers found that natural selection is favoring certain health-related traits while selecting against traits linked to higher educational ...

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.

The time for speculating is over. We now know the roster of the debut Natural Selection Tour (NST) ski event. If you clicked on this article, you came for those names, so we’ll lead there. Keep ...

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 ...

The proportion of well-adapted organisms in a population can increase over the generations by the process of evolution by natural selection.
