One fish species occurs by itself in several nearby lakes. The other occurs by itself in other lakes (Lakes N, O, P, Q, ... Y). However, they co-occur in lake Z, but do not interbreed (one breeds in the spring in the lake itself, and the other breeds in streams feeding the lake in the fall.)

b. Phylogenetic speciation

Explanation:

Autapomorphies are molecular or morphological traits found in a unique taxon. An autapomorphy is not found in outgroup and therefore these traits are used to classify a group into a category (i. e., species, genera, family, etc)
