A. What kind of speciation do we normally associate with members from one population being geographically displaced to a new, smaller population? Geospiza scandens
B. What kind of speciation do we normally associate with members of a population that become ecologically, genetically or behaviorally distinct within that population such that they become reproductively isolated?
Explain into details the concept of speciation .
Describe the steps involved in allopatric speciation.

A pregnant female rat is transported by an ocean liner to a new continent. B. A meadow containing several species of grasses is exposed to a pesticide that promotes nondisjunction. C. In a very large lake containing several species of fish, the water level gradually falls over the course of several years. Eventually, the large lake becomes subdivided into smaller lakes, some of which are connected by narrow streams.arrow_forwardCan speciation occur without complete physical separation of populations?arrow_forward
