|Owing to this struggle for life, any variation, however slight and from whatever cause proceeding, if it be in any degree profitable to an individual of any species, in its infinitely complex relations to other organic beings and to external nature, will tend to the preservation of that individual, and will generally be inherited by its offspring. The offspring, also, will thus have a better chance of surviving.
– Charles Darwin (1809-1882)
|Let us understand what our own selfish genes are up to, because we may then at least have the chance to upset their designs.
– Richard Dawkins (1941 -)
