Seven species of snapping shrimp are found on either side of the Isthmus of Panama. What data provides good evidence that this is speciation by vicariance?

a. That populations on opposite sides of the Isthmus are reproductively incompatible. Choice

b., The DNA of each current species is most similar to that of a species found on the opposite side of the current Isthmus. Choice

c., The rate of evolution can be calculated because the populations have been separated for about 3 million years. Choice

d., That it takes about 3 million years for accumulation of enough mutations to result in new species of snapping shrimp.

The correct option is A.

Vicariance speciation refers to the type of speciation in which populations of the same species are separated from one another by means of geographical barriers to the extent that the species can no longer exchange genetic material, that is, they do not come together for reproduction purpose.
