Document Summary
Biological evolution - changes that take place in the genetic and physical characteristics of a population or group of organisms over time. Adaptive significance - the effectiveness of behaviour in aiding organisms to adapt to changing environmental conditions. Ultimate causes - evolutionary conditions that have slowly shaped the behaviour of a species over generations. Proximate causes - immediate environmental events and conditions that affect behaviour. Culture - the sum of socially transmitted knowledge, customs, and behaviour patterns common to a particular group of people. Artificial selection - a procedure in which particular animals are deliberately mated to produce offspring that possess especially desirable characteristics. Natural selection - the consequence of the fact that, because there are physical and behavioural differences among organisms, they reproduce differentially. Within a given population, the survivors will produce more offspring than the other animals. Reproductive success - the number of viable offspring produced compared to other members of the same species.
