Question

Who was the first person living in earth

Answer 1

Answer :

There is no first person who we can point to by name or look at the fossilized bones of and say "Eureka! that person is the first human." Van Arsdale is saying that scientists look at a whole population of people over several generations that share the same characteristics and when they see those characteristics, like hands that can hold tools, or bodies that allow us to walk on two feet instead of using our arms and hands to help us walk, they can start to see a new species.
