Evolution can be defined as the change in the frequency of a phenotype in a population over many generations. Mutations can be inherited if they occur in DNA that is passed on to the next ...

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.

But there is another, more compelling reason for why life history evolution is important: adaptation by natural selection is based on variation in Darwinian fitness among individuals, and since ...

Evolution works thanks to a process called natural selection. Life-forms that have traits that make them better suited to a certain environment — whether icy tundra or deep-sea volcano — have ...

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 ...

It is one of the processes by which species change from generation to generation, and is a crucial element of the theory of evolution. A classic example of natural selection at work is the origin ...
