WebScience Biology Q&A Library Step 1 - Below is a basic phylogenetic tree for how canids evolved. For a group to divide into two species, the gene pool must somehow be divided so that some members of the species can no longer reproduce with some others. This is called reproductive isolation. There are many ways this can happen. WebThis is known as "reproductive isolation." Does the isolation concept make the theory of evolution more viable? When a small population from a species becomes isolated, the …

Select one: a. gene flow O b. reproductive isolation c. gene pool expansion d. hybrid formation Imagine a hybrid zone between two sister species that occasionally interbreed. WebWith its gene pool isolated, a separate population can follow its own evolutionary course. In the formation of many species, the initial isolation of a population seems to have been a geographic barrier. This mode of evolving new species is called allopatric speciation. Many factors can isolate a population geographically. picture of first goggles
