Consider the cladogram. according to the cladogram, which organisms have roundworms as a common ancestor?

The correct answer is Mollusks, Echinoderms, Chordates, and Annelids. This is basically how evolution works, at a certain point in the past, there was a transitional organism that eventually developed into roundworms and the other part of his species that was exposed to other things evolved into other transitional organisms who evolved eventually into these 4 groups.

True to the fact it is actually false
