Assume a large mountain range is formed, dividing multiple populations of different species. After a vicariant event such as the one described, how would sister taxa appear on a phylogenetic tree?

Species on either side of the mountain would be more closely related to each other than to species on the same side of the mountain.

The disruption of gene flow would simply result in subspecies being formed, and there would be no change in how the taxa are related.

Species on the same side of the mountain would be more closely related to each other than to species on the other side of the mountain.

It would be impossible to determine how the species are related.
