Evolution and Natural selection shapes organisms and diversity

Biological evolution = genetic change in populations of organisms across generations
May be random or directed by natural selection

Natural Selection = the process by which traits that enhance survival and reproduction are passed on more frequently to future generations than those that do not

Natural selection is the process by which traits that enhance survival and reproduction are passed on more frequently to future generations
In 1858, Darwin and Wallace both proposed natural selection as the mechanism of evolution

Adaptive Trait (Adaptation) = a trait that promotes reproductive success
A trait that reduces success is said to be maladaptive
