Question

A. Based on this neighbor joining tree,would you argue that there is evidence that any of the “Unidentified” specimens, constitute a new species of Coryphopterus? Defend your answer.
B. At the time these data were published, there were 12 known species of Coryphopterus, but only 5 of these known species were included in the above dataset. With this new information, would you change your answer(s)? If so, why? If not, why not.

Explanation / Answer

A. Yes

The unidentified specimens could be different species. This is due to the fact that these unidentified species belong to different clades (not clustered into a single clade). SO, they are very likely to be different species.

The other reason is that there is a single clade containing only unidentified specimens. So, even if the unidentified specimens in each clade belong to their respective species, this clade would constitute a different species.

B. As mentioned earlier, the unidentified specimens could be new species.
