Discuss the stages of human evolution in a chronological order

1. Hominidae (6-7 million years ago)

- Ape-like ancestors who walked upright on two legs
- Lived in forests and savannas
- Brain size: 400-500 cc
- Tools: Simple stone tools for cutting and scraping

2. Australopithecus afarensis (3.9-2.9 million years ago)

- Known as "Lucy"
- Bipedal with a smaller brain (450-550 cc)
- Lived in savannas and woodlands
- Used stone tools for hunting and gathering

3. Homo habilis (2.4-1.4 million years ago)

- More human-like with a larger brain (600-800 cc)
- Made more complex stone tools, including hand axes and choppers
- Lived in savannas and open grasslands

4. Homo erectus (1.9-0.1 million years ago)

- Moved out of Africa and spread into Asia and Europe
- Taller and more robust than earlier hominids
- Brain size: 800-1200 cc
- Used advanced stone tools and controlled fire

5. Homo neanderthalensis (c. 300,000-40,000 years ago)

- Heavily built with a large brain (1200-1700 cc)
- Lived in cold climates in Europe and Asia
- Produced sophisticated tools and art
- Coexisted with Homo sapiens

6. Homo sapiens (c. 300,000 years ago - present)

- Modern humans
- Highly intelligent with a complex brain (1300-1500 cc)
- Spread to all continents
- Developed advanced technology, including agriculture, metallurgy, and writing
