Question

Which of the seven primate groupings (Strepsirhini, Haplorhini, Catarrhini, Platyrrhini, Tarsiiformes, Cercopithecoidea, and Hominoidea) do you expect to have the least “human-like” characteristics? Which do you expect to have the most “human-like” characteristics? Be sure to explain your answers from a taxonomic perspective.

Answer 1

Answer :

Least human like is STRESIRRHINI.

Most human like is HOMINOIDEA.

In evolution of primates first came Haplorhini and strepsirrhini. Of that strepsirrhini diverted earlier.

So strepsirrhini have least human like characteristics.

Next in the evolution comes platyrhhini, catarrhini, and tarsiiformes. Of this tarssiformes branches out from human evolution.

Then came cercopithecoidea and hominoidea.

Hominoidea is the most nearer node to humans.

So most human like characteristics is for hominoidea.
