Document Summary
Orchid from madagascar with long floral tube pollinated by night-flying moth with exceptionally long proboscis: darwin predicted the existence of the moth, discovered a century later, example of co-adaptation. Fitness relative genetic contribution of individuals to next generation as a result of differences in viability and fertility darwinian fitness. Selective advantage some individuals better adapted to the environment and thus have higher fitness. Adaptation any trait that contributes to fitness by making organism better able to survive or reproduce in a given environment (noun) or the evolutionary process that leads to the origin and maintenance of such traits (verb) Domesticated plant and animals; selection experiments in genetics selected by humans for a purpose or goal. No purpose or goal; simply a blind mechanistic process with no foresight selection by abiotic and biotic environments. Evolution by pollution: evolution of industrial melanism in the peppered moth, evolution of heavy-metal tolerance in grass species.
