Human evolution is a fascinating scientific subject that explains how our species developed over millions of years.
A simplified educational timeline often discusses seven groups:
Dryopithecus
Ramapithecus
Australopithecus
Homo habilis
Homo erectus
Neanderthals
Homo sapiens

These groups help introduce important developments such as upright walking, changes in brain size, early toolmaking, migration and cultural development.
However, scientists do not consider these seven groups a fixed sequence of direct ancestors. Human evolution involved several branches, and some groups existed at overlapping times.
The Campus Review has published a guide explaining these groups and their importance in understanding human origins.
