Based on the information about snapping shrimp populations separated by an isthmus, what can be inferred about their phylogenetic relationships?
Each pair of separated species are each other's closest relatives.
Learn about the morphospecies concept in biology, which uses different morphological characters to distinguish species. Explore how individual lineages differ in size, shape, or other characteristics, and the advantages and disadvantages of this concept.
