Which condition is unlikely to lead to allopatric speciation?
A) A lava flow separating a formerly contiguous forest into isolated patches
B) The Rocky Mountains separating eastern from western North America
C) Sea level rise eliminating a land bridge between North and South America
D) A glacier receding, joining habitat that was formerly separated
E) River erosion creating a canyon separating two sides of a plain

Question

A glacier receding and joining habitat that was formerly separated would not lead to allopatric speciation as the populations were not isolated from each other for a significant period of time. The other options involve physical barriers that could lead to geographical isolation and potentially allopatric speciation.
