A species may be reproductively isolated through which of the following causes?
The correct options are
A ecology
B anatomy
C behaviour
D all of the above
Speciation is the formation of new and distinct species in the course of evolution. Speciation involves the splitting of a single evolutionary lineage into two or more genetically independent ones.
In eukaryotic species there are two important processes that occur during speciation: the splitting up of one gene pool into two or more separated gene pools (genetic separation) and the diversification of one phenotypic form into many (phenotypic differentiation/ behavioral differentiation). Geographical isolation / ecological separation also add up to the process of speciation whereas genetic differences bring about anatomical and behavioral changes. All such separations bring about reproductive isolation which leads to different species in due course of time.
