Fossils reveal that Eocene primates like Smilodectes were adapted for life in the trees. Their large, forward-looking eyes could focus simultaneously on the same point, giving them excellent depth perception. Stereoscopic vision, combined with an opposable thumb and a relatively large brain, enhanced their ability to live and feed treetops, beyond the reach of most terrestrial predators
