Natural selection will only cause evolution if there is enough genetic variation in a population. Before the discovery of Mendelian genetics, one common hypothesis was blending inheritance. But with blending inheritance, genetic variance would be rapidly lost, making evolution by natural selection implausible.
1. The answer is Genotypic. Evolution refers to the genetic change in a population over the time. 2. The answer is No. Jumping Jack Flash's speed is a result of diet and exercise, not by a genetic trait. 3. Natural Selection is the process in which an organism is well adapted to the environment.
