The angiosperm radiation hypothesis proposes that: certain primate traits were responses to the acquisition of fruit during the Cenozoic . In Europe and Africa tropical forests became woodlands and grasslands, while in Asia decreased rainfall resulted in reduced forests and decreased fruit availability.

The visual predation hypothesis proposes that most primates' visual traits evolved to adapt to preying on small animals and insects. Critics of this idea have argued that because insectivory is uncommon among extant primates it is unlikely to have been a major influence on early primate evolution. The visual predation hypothesis acknowledges that some arboreal species (such as squirrels) do not possess these key primate features, so instead it focuses on stereoscopic vision and grasping as means of catching insects. which takes up an evolutionarily intermediate position in between basal angiosperms and eudicots .
