1
Speciation
Origin of a new species.
2
Biological Species Concept
Defines "specie" as a population who's members can produce fertile offspring with each other, but cannot do the same with members from a another species.
3
Ecological Species Concept
Defines "specie" depending on the resources a population typically uses.
4
Morphological Species Concept
Defines "specie" depending on their structural features. Defines the difference between species.
5
Phylogenetic Species Concept
Defines "specie" depending on genetic history, such as genetic markers.
6
Prezygotic Barriers
Impediments that hinder cross breeding between different species.
7
Habitat Isolation
Possible mates do not meet due to living in different habitats.
8
Behavioral Isolation
Possible mates can't communicate due to different mating signs.
9
Temporal Isolation
Possible mates cannot mate due to different mating time periods.
10
Mechanical Isolation
Possible mates cannot mate due to different structurally built reproductive organs.
11
Gametic Isolation
Possible mates cannot mate due to lack of fusion of gametes.
12
Geographical Isolation
Possible mates never meet due to specific biomes.
