Question

Do you think that most of the anatomical differences in the Homo fossil forms are due to variation within a species as opposed to speciation (different species)? Why?

Answer 1

Early human fossil forms have been identified more than 6000, from these fossils we can understand their growth, adaptation, male and female differentiation etc. Yes there are anatomical differences in the fossil forms due to variation within species. For example : the species homo erectus which had a longest temporal span differ from ancestral hominins. Human erectus has an increased body size means hight than their early hominins. And homo erectus have larger brain size than hominins. So there is differentiation occurs in same species. Due to their increased body weight and brain the energy sources also increases which led them in hunting. This behaviour helps in evolutionary change and transformation of early hominins to a homo erectus.
