Question

which lists the correct sequence of events for evolution to occur through isolation?
o founding population arrives, biogeographic isolation occurs, genetic changes occur, reproductive isolation results
o genetic changes occur, founding population arrives, reproductive isolation results, biogeographic isolation occurs
o biogeographic isolation occurs, founding population arrives, genetic changes occur, reproductive isolation results
o founding population arrives, genetic changes occur, biogeographic isolation occurs, reproductive isolation results

Explanation:

For evolution to occur through isolation, first, a founding population arrives in a new area. Then, biogeographic isolation (geographic separation) occurs. Over time, genetic changes happen within this isolated population. Eventually, these genetic changes lead to reproductive isolation (unable to interbreed with the original population).

Answer:

Founding population arrives, biogeographic isolation occurs, genetic changes occur, reproductive isolation results.
