Try to trace the various components of human evolution (hint: brain size and function, skeletal structure, dietary preference, etc.)
The various components of human evolution are as follows:
S.No. | Name | Time period | Brain capacity | Height and structure | Features |
1. | Dryopithecus | 15 m.y.a. | - | Walked similar to chimpanzees or gorillas | • More ape like • Large canines, both arms and legs of same size |
2. | Ramapithecus | 14-8 m.y.a. | - | Comparatively erect posture (not complete) | • More man like • Smaller canines, larger molars |
3. | Australopithecus | 2 m.y.a. | 450 cc | Fully erect 1.05 m in height | • Probably lived in East African Grasslands. • Hunted with stone weapons. • Fed on fruits |
4. | Homo habilis | 2-1.5 m.y.a. | 650-800 cc | Erect posture 105 m in height. | • First human like being-hominid • Did not eat meat. • Developed tools |
5. | Homo erectus | 1.6 m-200,000 y. a. | 900 cc | Fully erect posture 1.5-1.7 m in height. | • Ate meat • Left African subcontinent and spread to other parts of the world. • Used hides to protect their body and buried their dead. |
6. | Homo sapiens | 400,000-40,000 y.a. | Neanderthals had the brain capacity of 1400 cc. | Fully erect posture 1.5-1.8m in height | • Developed into different races. • Cultivated crops and lived in settled civilisations. • Domesticated various animals for food and protection. |
7. | Homo sapiens sapiens | 40,000y.a.- present | 1200-1600 cc | Fully erect posture 1.5-1.8 m in height. | • The modern day man, living in civilisations. • Omnivorous. |
