If you look at the traits for the common Haplorhine ancestor, we can say with near certainty that it was .

Altruistic behavior

You find a fossil primate, and you decide to call it apidium. It is 35mya, and it has the following traits: postorbital closure, forward facing eyes, nails on all fingers, fused frontal suture, and a 2.1.3.3. dental formula. Thinking about the chart, what is this species? (i.e. where would you place this species?)
