What does a reduced snout in the primates tell us about their activity patterns and lifestyle? How does this differ from the cat, which in the wild, is a predator.

Primates are vision-orientated and are distinguished from other mammals. The reduction of the snout in primates is a correlate of the diminution of the sense of smell, or olfaction. To a great extent, visual acuity and manual dexterity have replaced the sensitive, inquiring nose found in so many nonprimate mammals. Furthermore the evolution of enhanced motion detection also accured indicating that the primates went from nocturnal to diural lifestyle. From catching insects to onmivory. Therefore the differece from cats.
