[7] Humans have the proportionately smallest male canine teeth among all anthropoids and exhibit relatively little sexual dimorphism in canine tooth size.
Not only do the back molars have double the area that the molars of modern humans possess, but the premolars and the first and second molars were found to be four times larger than the teeth found in humans. [12] This has been interpreted as researchers as evidence for the hominids chewing predominantly with their back teeth. [13]

"At this time we see a flurry of evolution in the forerunners of mammals, such as Dimetrodon, an animal the size of a mountain lion that looked something like a big lizard with a giant sail on its ...

Eye movements are either conjunctive (in the same direction), version eye movements, usually described by their type: saccades or smooth pursuit (also nystagmus and vestibulo-ocular ...
The muscles connected to the ears of a human do not develop enough to have the same mobility allowed to monkeys. Arrows show the vestigial structure called Darwin's tubercle. In the context of human evolution, vestigiality involves those traits occurring in humans that have lost all or most of their original function through evolution. Although ...
