For Natural Selection we have terms and definitions in 12 topics. The topics are Anthromorphemics, Anthropology, Biodiversity, Canine, Climate, Evolution, Fish, Fossils, Global History, Mind, Science and Science And Religion.

The process whereby members of a species who have more surviving offspring than others pass their traits on to the next generation, whereas the less favored do not do so to the same degree.

The process whereby members of a species who have more surviving offspring than others pass their traits on to the next generation, whereas the less favored do not do so to the same degree.
See more Anthropology Terms ...

The process by which genetic traits are passed on to each successive generation. Over time, natural selection helps species become better adapted to their environment. Also known as survival of the fittest, natural selection is the driving force behind the process of evolution.
See more Biodiversity Terms ...

The process in nature by which, according to Darwin's theory of evolution, only the organisms best adapted to their environment tend to survive and transmit their genetic characteristics in increasing numbers to succeeding generations while those less adapted tend to be eliminated.
See more Canine Terms ...

The process of survival of the fittest by which organisms that adapt to their environment survive while those that do not adapt disappear.
See more Climate Terms ...

The differential survival and reproduction of classes of organisms that differ from one another in on or more usually heritable characteristics. Through this process, the forms of organisms in a population that are best adapted to their local environment increase in frequency relative to less well-adapted forms over a number of generations. This difference in survival and reproduction is not due to chance.
See more Evolution Terms ...

Differential survival and reproduction among members of a population or species in nature; due to variation in the possession of adaptive genetic traits.
See more Fish Terms ...

The differential survival and reproduction of classes of organisms that differ from one another in on or more usually heritable characteristics. Through this process, the forms of organisms in a population that are best adapted to their local environment increase in frequency relative to less well-adapted forms over a number of generations. This difference in survival and reproduction is not due to chance.
See more Fossils Terms ...

The biological process by which variations that enhance a population's ability to survive in a particular environment become dominant in a species over very long periods and lead to the evolution of a new species. (p. 6)
See more Global History Terms ...

Charles Darwin's theory of biological evolution, based on the survival and replication of the fittest and most adaptable genes, through competition over limited natural resources.
See more Mind Terms ...

Theory that explains genetic changes occurring in a species over a long period of time
See more Science Terms ...

Variations within a population that confer a slight competitive advantage for certain individuals over others resulting in differential survival rates. Darwin argued that through natural selection new species come to existence. p.154
