Document Summary

Darwin was interested of the stem of the orchid and inferred that this was an adaptation and on the base was nectar. Darwin predicted the existence of the moth as the main pollinator to this orchid. Relative genetic contribution of individuals to next generation as a result of differences in viability and fertility. Some individuals better adapted to the environment and thus have higher fitness. Any trait that contributes to fitness by making an organism better able to survive or reproduce in a given environment (noun) The evolutionary process that leads to the origin and maintenance of such traits (verb) Domesticated plant and animals; selection experiments in genetics. Has a purpose or goal plant breeder will decide to increase yield of a particular crop. No purpose or goal; simply a blind mechanistic process with no foresight. Look at the variance instead of the mean.
