Question

Give 3-4 reasons explaining why the Kasaki cluster with sequences have 3 different species names

Why species 1, 2, and 3 is in the middle of the Kasaki cluster. The relationship with Kasaki nozomi sp. (above), Kasaki sp. (below), Kasaki mizore sp. and so on

Keywords: common ancestor, same species / different species, are species 1-3 new species, relatedness (which one is more related, which is less), branches.

Hint: anatomically, species 1-3 have similar morphology as the Kasaki sp. (these are made-up names.)

Answer 1

Answer- The reasons being the difference in the genotypes, differences in the habitat location and differences in the behaviour and interaction with environment.

The species1, 2 and 3 are present in between the kasaki species because these species were speciated before the speciation of the middle kasaki species.
