These sideways-facing eyes allow an animal to see in front of and behind itself, an ability also known as panoramic vision. ... "Animals outside of leafy environments do not have to deal with clutter no matter how big or small they are, so there is never any X-ray advantage to forward-facing eyes for them," says Changizi.

2. Allman discussed in his book “the [adaptive] advantages and costs of front-facing eyes” for early primates (pp. 124-128). What are the potential advantages and costs? Also, how might the formation of front-facing eyes be related to some social behaviors of primates, such as altruism or cooperation?

In diurnal non-human primates, ... front-facing eyes have overlapping fields, so there would be no advantage in having eye-specific cortical segregation. Instead, a very large area of the right occipital responds to the left side of the visual field, while a large area of the left occipital responds to the right side of...

Most animals--fish, insects, reptiles, birds, rabbits, and horses, for example--live in non-cluttered environments like fields or plains and have eyes located on either side of their head. These sideways-facing eyes give an animal panoramic vision--the ability to see in front and behind itself.

These early prosimians are sometimes referred to as the first "euprimates" (literally, "true primates") because they had modern primate traits such as large brains, front-facing eyes with post-orbital bars, and grasping hands and feet with nails instead of claws.

Why? Primates have an increased emphasis on vision, so natural selection acted to position the eyes best for taking in the most visual stimuli. ... Nycticebus pygmaeus (Pygmy loris) This loris is descending a branch, taking advantage of the limb motion afforded by two bones in the primate forearm and lower leg.
