Speciation
The formation of one or more species from a single species
The formation of one or more species from a single species

Isolation
Occurs usually through geographical isolation, by distance or by an impassible barrier

Isolation
Genetic divergence
Can no longer interbreed and produce fertile offspring
Can no longer interbreed and produce fertile offspring
Genetic divergence
Migration
The movement of individuals into, out of or between populations and can change the numbers and types of alleles in a population
The movement of individuals into, out of or between populations and can change the numbers and types of alleles in a population
Migration
Mate choice
If parents are limited or selective in mate choice, a limited set of traits will be passed on to the next generation
If parents are limited or selective in mate choice, a limited set of traits will be passed on to the next generation
Mate choice
Mutation
Any change in genetic material from one generation to the next and can add a new allele to a population
Any change in genetic material from one generation to the next and can add a new allele to a population
Mutation
Genetic drift
The random change of allele frequency in a population
The random change of allele frequency in a population
Genetic drift
Convergent evolution
The process by which unrelated species become more similar as they adapt to the same environment
