He illustrates his stand with the examples of the theories surrounding the evolution of man by starting with the rather shocking theory that we all as humans originate from the continent of Africa
This topic is very important to biological and physical anthropology because it explains why we are all so different racially and genetically and seeks to explain with the help of many theories whether Darwin's theory is actually right in saying that as humans we have only recently evolved from apes. He compares the "originate in Africa thesis" with the "out of Africa thesis" where he is trying to explain the origin of our genetics and evolution.
The author uses the technique of taking up many hypotheses and theories and assessing their truth and in the end he gives his verdict in the favour of the theory given by Darwin, the Out of Africa hypothesis.
" This theory maintains that modern humans evolved in Africa and then spread around the world. Boiled down to its essence, the hypothesis states that modern humans are both relatively recent (100,000 to 200,000 years old) and African in origin. A major prediction of this hypothesis is that the earliest remains of modern humans will be found in Africa, dated to an appropriate time period."
The author goes on to discuss the " Multiregional hypothesis" which he argues depicts that we as modern humans evolved from different locations and hence our racial and genet ...
