Nvironment and Evolution of human being

(PLEASE BE WRITTEN FROM SCRATCH!!!) And including the bibliography.

How environments effect the evolution of the structure of human being (or the relationship between environment and human evolution) in the past. As researches from geneticists and natural historians provided that there were series evolutions of human being in the past. Evidences such as fossils of early human skull and bone are being found and they proves that there were differences on the structure of human being in different periods, especially human skull. Some comparisons to eaarly human such as Lucy.

Also it well be nice to look up Adrienne Zihlmans article about paleosols to suggest and support the relationship between environment and human evolution.
