Direct dating of fossils
Modern humans have very large brains, which vary in size from population to population and between males and females, but the average size is approximately 1300 cubic centimeters.
Anatomically, modern humans can generally be characterized by the lighter build of their skeletons compared to earlier humans.
It is rumored that in 1994 paleontologist Robert Bakker formally declared the skull of Edward Drinker Cope as the “lectotype”, a specimen essentially serving as the type specimen.
When Cope, himself a great paleontologist, died in 1897, he willed his remains to science, and they are held by the University of Pennsylvania.
Its name, which means ‘handy man’, was given in 1964 because this species was thought to represent the first maker of stone tools.
Currently, the oldest stone tools are dated slightly older than the oldest evidence of the genus A team led by scientists Louis and Mary Leakey uncovered the fossilized remains of a unique early human between 19 at Olduvai Gorge in Tanzania.
Paleoanthropologists are constantly in the field, excavating new areas, using groundbreaking technology, and continually filling in some of the gaps about our understanding of human but their tooth enamel was still thick and their jaws were still strong, indicating their teeth were still adapted chewing some hard foods (possibly only seasonally when their preferred foods became less available).
