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 ...

Natural selection is a process by which a species changes over time in response to changes in the environment, or competition between organisms, in order for the species to survive. The members of ...

Darwin viewed evolution by natural selection as a very gradual mechanism of change within populations, and postulated that new species could be the product of this very same process, but over even ...

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 ...

In fact, the process of natural selection feeds on randomness. It feeds on accident and contingency, and exploits that in ways that couldn't be predicted. It's still an inexorable process.

The early part of the twentieth century saw evolutionary theory embattled by disagreements over Darwin's emphasis on natural selection. The then-newly rediscovered work of Gregor Mendel in the ...

From Paleocene epoch predators to beloved companions, cats have embarked on an incredible evolutionary journey. Their initial ...

The tendency of human beings to live in settlements and cultivate fields can also be traced to this natural selection process. One way to look for genes that have recently been changed by natural ...
