Who's Who Among the Early Hominids?


Susman, Randall. 
"Who's Who Among the Early Hominids?"
Odyssey Adventures in

The records of early Hominins also known as the Ape Men and our 
ancestors date back to 7m.y.a and supports evidence of our close 
relationship with, and evolution from, the African ape.   
The fossil record of early hominids evolution show Primitive and Advanced. 
Primitive focuses on ape-like evolutions while Advanced focus on 
Human-Like evolutions. The definition of Hominins are members of a 
group of primates that includes modern humans and all of our ancestors. 
Homininds only refer to the living primates such as us.
Some examples of early hominins  
  • Sabelanthropus
  • Orrorin
  • Ardipithecus
They are hominins because they are dead now, if they are living they would be hominids.When we study fossils to classify what species they are in we are classifying the taxonomic. Taxonomic is having to do with the classifying of living things, so classifying go hominins.
When we are studying fossils of species we can lean about the positional behavior, 
meaning the way animals stand and move.
Also we can look at the wear patterns on the teeth and this will determine what the hominin ate. One of the most important parts is looking at the sexual dimorphism, this is looking at the difference of size and shape between males and females, it is important to when studying the fossil record to acknowledge if the fossil is of a male and female of the same species or of different species.
All of the early homos that lived in the past are the first members of our species. Most of the fossils of early homos were found in east and south Africa about 2 m.y.a.The period of the homos was an epoch period. Epoch is a period of time in history that is important/ noteworthy. 
The early homos such as
  • Homo Erectus (The Upright Man)
  • Homo Habillis (The well known Handy Man)
  • Homo Rudolfensis
These three to me are the most well known hominins of the Homo species. There are others such as the
  • Homo Georgicus
  • Homo Florensis
  • Homo Neanderthalensis
