The primates that possess characterics like bipedalism, smaller canine size and bigger brain size are hominins. Humans are the modern Hominins and the fossils reveal that several species of hominins are extinct. Homo is a type of Hominin that lived around 1.9 m.y.a and it is the immediate predecessor of Homo sapiens. Paleontologists and archeologists have classify each time they discover new fossils that have primates and or derived characteristics. The two groups of anthropologists are lumpers and splitters and they organize species depending other their similarities and differences. Splitters focus on difference between the Hominin species, but the Lumpers focus on the similar hominids are primates that share characteristics such as "bipedalism,

Homo have non projecting canine, rounded jaw, reduced prognathism, and bigger brain size. Homo Habilis- is the earliest members of the genus of Homo. Homo erectus have lived contemporaneously with Homo habilis between 1.9-1.4 million years ago. Homoheidelbergensis have larger browridge, larger brain case and flatter face than early human species. They were the first human species who adapted to the cold climate and their short wide bodies reveals such adaptation. Also, homoheidelbergensis were the first human species who hunted animals and built shelters. Homo neanderthalensis is our closest human relative who are extinct. They middle face was large and their cheek bones were angles. Their big nose was an adaptation to the cold weather because their nose warmed the cold and also their bodies were shorter than us. But they had a brain size the same size as ours. Neanderthals made clothing, controlled fire, hunted animals and utilized complicated tools. Also, they planted food and made ornaments that were appears symbolic and they buried their dead bodies. Based on mentioned characteristics, lumpers classify neanderthalesis as human species rather than distinct species. Homo sapiens are the currently living human beings who have evolved from Africa and they are characterized by their lighter build skeleton than the earlier human species and also have very large brain. Splitter states that neanderthalesis were distinct species because they had angled cheeckbones and also they were shorter and stockier than
