Second, mutation will generate variation in life history around the mean.

To be effective, though, the rules have a conditional character to them which means, of course, that they generate variation in behaviour in response to variable environments.

Then, mechanisms that provide selection, generate variation and establish self-replication, must be identified.

These fields should generate fifth forces and variation of the fundamental constants.

There are several variants of the lyrics; the dramatic and creative talents of the caller generate considerable variation.

The shift-tilt reverse Scheimpflug principle has been used for more than a decade, making Smallgantics a computer generated variation of an existing optical technique.

Hosts continue to evolve resistance to parasites and parasites continue to bypass resistant mechanisms, continuously generating genetic variation.

The DGC proposes that differences in representation generate variation in forms of reasoning without assuming a multiple system framework.

Sexual reproduction generates more variation (and thereby evolvability) relative to asexual reproduction (see evolution of sexual reproduction).
