scientific explanation of how the process of evolution takes place
Theory of Evolution
process which individuals with certain traits are more likely to survive and reproduce under a particular set of environmental conditions than those without traits
Natural Selection
process where one species splits into two or more different species
Speciation
Two Types of Isolation
Reproduction, Geographic
occurs when mutation and change by natural selection operate in the gene pools of geographically isolated populations
Reproduction Isolation
occurs when different groups of the same population of a species become physically isolated from one another for a long period of time
Geographic Isolation
