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, reduced canine size, and increasing brain size.rities between the hominin species. Lumpers classification is based on anagenesis which refers to the formation of species without branching into evolutionary line. Lumper’s goal is to have as few groups of species as possible as they place many fossils in the same category. The lumpers use Multi …show more content…
The teeth and the jaw are much larger than humans. But their teeth are still more similar to human because their jaw is parabolic like human and the size of canine teeth is smaller than afarensis canine teeth. Africanus’s primitive features are short sub adulthood, and is three feet tall. Thus, Lumpers claims that Australopithecus Africanus are ancestral to Homo because they share derived features which are bipedalism, reduced pragmatism and non-projecting canine. Also, male Africanus and female Africanus are much more alike. However, Splitters do not consider Africanus ancestor to Homo because its canines were more pointed with larger roots than Homo’s are. Also, Africanus’s brain size only increased slightly which was 490 cm which very small relative to 1350 cm cranial capacity of Homo
