natural selection is a mechanical process with no foresight, which can only blindly favor short-term gain.
Breast milk is the perfect food, formed by natural selection to have everything the developing child—and its microbiota—needs.
In natural selection you have to wait for generations to go by for the improvement.
Our brains can foresee that if we let natural selection take its course then it could be disastrous in the long run.
“natural selection has duped us with an emotion that encourages group thinking,” Pagel writes.
Which, of course, is not equivalent to showing that all instincts must have been developed by natural selection alone.
Darwin and the Darwinians would have said—natural selection.
The course of a true theory is very different, as may be well seen by the progress of opinion on the subject of natural selection.
So much, then, as a statement of the theory of natural selection.
In the course of events and natural selection they had increased to eleven.
natural selection n.
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 characters in increasing numbers to succeeding generations while those less adapted tend to be eliminated.
natural selection |
The process by which organisms that are better suited to their environment than others produce more offspring. As a result of natural selection, the proportion of organisms in a species with characteristics that are adaptive to a given environment increases with each generation. Therefore, natural selection modifies the originally random variation of genetic traits in a species so that alleles that are beneficial for survival predominate, while alleles that are not beneficial decrease. Originally proposed by Charles Darwin, natural selection forms the basis of the process of evolution. See Notes at adaptation, evolution. Compare artificial selection.
A process fundamental to evolution as described by Charles Darwin. By natural selection, any characteristic of an individual that allows it to survive to produce more offspring will eventually appear in every individual of the species, simply because those members will have more offspring.
Note: The expression survival of the fittest was used to describe this process in the nineteenth century but is not favored by modern scientists.
