Anthropology 101?

Primates have evolved in arboreal habitats.

What selective pressures did such environments impose?

I don't know what this means.

    Selective pressure means the difficulties that primates face when trying to survive and reproduce in arboreal environments.

    For example, arboreal environments put pressure on an animal's ability to climb and to stay up in the trees because a fall would be dangerous. The ability to climb and the ability to stay above the ground without falling down to it would be selective pressures.

    In contrast, the ability to climb would not be a selective pressure to an aquatic animal or an animal living on the ground since their survival would not be affected if they cannot climb.

    Another selective pressure is the ability to find food in the trees, and catch it.

    Arboreal locomotion is the locomotion of animals in trees. In habitats in which trees are present, animals have evolved to move in them. Some animals may scale trees only occasionally, but others are exclusively arboreal. The habitats pose numerous mechanical challenges to animals moving through them and lead to a variety of anatomical, behavioral and ecological consequences as well as variations throughout different species. Brachiation is a form of arboreal locomotion in which primates swing from tree limb to tree limb using only their arms. Specialized locomotor behaviours, such as brachiating, are thought to have evolved from arboreal quadrupedalism. The transition to brachiation is regarded as a major shift during primate evolution.

    Hmm, well, if you don't know what "selective pressures" means, and if you can't even figure out how to look it up, then you're going to have a really hard time in the rest of Anthro 101. Why not ask your teacher for help before you fall even farther behind?
