SPECIES AND SPECIATION

What is a species?Morphological Species ConceptPhylogenetic Species ConceptBiological Species Concept

Morphological Species ConceptUse physical similarities to classify species

Phylogenetic Species ConceptUse shared, unique genetic history to classify species

Biological Species ConceptUse ability to mate and produce offspring that can also mate and reproduce to classify species

How do species form?When a group of individuals

remains isolated from the rest of its species long enough to evolve different traits

How can some members of a species become separated from the main group?

Geographical IsolationPhysical barrier

Temporal IsolationReproduce at different times

Habitat/Spatial Isolation Occupy different habitats in the same area

Behavioral IsolationDifferent courtship displays

Resource Isolation Use different resources in the same area

Mechanical IsolationPhysically incompatible
