This video outlines five different speciation processes that lead to new species.
It answers the question: how do new species arise?
Five different speciation processes or mechanisms are presented:
(1) Allopatric speciation.
(1) Peripatric speciation.
(1) Sympatric speciation.
(1) Parapatric speciation.
(1) Hybrid speciation.
Examples from nature and the lab for each process are discussed. These examples include Drawin's finches, snapping shrimp, sticklebacks, Drosophila, little greenbulls, hawthorn flies, cichlids, and dolphins.
