What Are the Major Milestones in Human Evolution?

[Campus reveiw]

Human evolution developed over millions of years. Scientists study fossils, stone tools, archaeological discoveries, and DNA to understand how human ancestors changed and adapted.



Important milestones include:

The development of walking on two legs

Changes in brain size and body structure

Early stone tool production

Expansion into new geographical regions

The emergence of modern Homo sapiens

Development of symbolic expression and complex cultures

Educational timelines often introduce groups such as Australopithecus, Homo habilis, Homo erectus, Neanderthals, and Homo sapiens.

However, human evolution was a branching process, with several related species existing at different times and sometimes overlapping.
