The Selfish Gene (1976), in which he notes that "all life evolves by the differential survival of replicating entities".

This is the law that all life evolves by the differential survival of replicating entities.

This is an example of coevolution because differential survival caused each organism to change in response to changes in the other.

Changes in allele frequency is mainly caused by natural selection, that is, by differential survival, and contribution to the next generation.

These individuals are then subjected to differential survival through the operation of a range of mortality factors that eliminate them either before or after reproduction.

Selection is the consistent differential survival and reproduction among genotypes.

In short, first the origin, second the differential survival and propagation.

Paleontologists are just beginning to study the causal structure of differential survival, and the jury will be out for some time.

It has been suggested this reflected developing strains in gender relations, but it may simply be a result of the differential survival of records.
