the study of the spatial distribution of organisms (biogeography). The goal of the chorological point of view is to know the character of regions and places through comprehension of the existence together and interrelations among different realms of reality and their varied manifestations, and to comprehend the earth surface as a whole in its ...
Chronology is the science of locating events in time. Methods of determining chronology are used in most disciplines of science, especially astronomy , geology , history , paleontology and archaeology .
The last common ancestor between humans and other apes possibly had a similar method of locomotion. 12-8 Ma The clade currently represented by humans and the genus Pan (chimpanzees and bonobos) splits from the ancestors of the gorillas between c. 12 to 8 Ma. [31] 8-6 Ma Sahelanthropus tchadensis
