Evolution And Evolution Of Primates - 1171 Words

There is a circumstance that has beset the understanding of evolution over time that there is no general theory involving primate evolution. Most of the theories are just mere speculation. Over the years, primates like gorillas, chimpanzees, and baboons all happened to have their turn in evolution. It was previously presumed that the taxon of interest happened to have the exact similar physiology and ecology as the analog taxon (Rafferty, 2010).The majority of the first primate species theories have been utilized because they solely share one fundamental characteristic with the hominines with the chimpanzees as the phylogenetic cousins. This paper addresses the different ecological conditions that handled the evolution of primates.

There was much speculation regarding the K/T boundary being caused by a meteorite. The impact of this event was believed to have led to extended volcanic activity periods that in turn further polluted the atmosphere. The impact of the K-T boundary happened to be attributed to the extinction of dinosaurs that might have been as a result of new diseases. The impact affected all living things including primates. The impact is believed to have drastically slowed primate evolution (Clyde, 2010). The Eocene era was the one that followed Paleocene period. There was mild climate during this time despite North America and Europe breaking the land. There was increased forest vegetation, sunny conditions and rainfall that started being observed at the poles. This period comprised the omomyids and the adapids primate groups. There happened to have differences and some similarities. Both happened to possess features linked with living the modern primates like grasping feet and hands that had nails rather than claws. They both had a postorbital bar that was complete (Soligo, 2007). They also had differences. The adapids happened to be huge, with a 1kg body mass. They had small orbits, implying diurnal lifestyles. These species ate fruits and leaves because
