Study Notes
Human Evolution
- Human evolution began over 6 million years ago and involved a series of stages and changes from the oldest ancestors to present-day humans.
- This process is known as hominization, which transformed the species to differ from all others on Earth.
Early Stages
- A population of Northwest African primates split into two groups, with one staying in the trees and the other migrating to the plains.
- The migrating group learned to stand on their forelegs, freeing their hind legs to eventually become hands.
- These primates, known as Australopithecus, started collecting fruits, hunting, and adapting to their environment.
Homo Habilis
- Australopithecus evolved into Homo habilis due to factors like climate change.
- Homo habilis created instruments for survival, walked upright, and manufactured stone utensils.
- Their brain was twice as large as that of Australopithecus.
Homo Erectus
- Homo erectus was the first to leave Africa and migrate to Asia.
- They had more capacity than Homo habilis, creating more complex stone instruments and covering their bodies with animal skins.
- They walked upright, discovered fire, and developed social coexistence, gathering in groups to survive.
Homo Sapiens
- Homo sapiens, also known as Modern Man, spread throughout the land, leaving behind instruments of stone, bone, and ivory.
- They developed painting, sculpture, and had a well-developed brain, allowing them to create, invent, and learn.
- They improved communication with others, using speech and more.
Present-Day Humans
- The last evolutionary stage resulted in physically modern humans, who developed their thinking and improved their abilities.
- Humans evolved from apes to become the most extraordinary and intelligent beings on the planet.
Human Evolution
- Human evolution started over 6 million years ago and involved multiple stages of transformation from ancient ancestors to present-day humans.
Early Stages
- A population of Northwest African primates divided into two groups, with one remaining in trees and the other migrating to plains.
- The migrating group adopted upright posture on all fours, freeing their hind legs to eventually become hands.
- They became Australopithecus, adapting to their environment by collecting fruits, hunting, and gathering.
Homo Habilis
- Australopithecus evolved into Homo habilis due to factors like climate change.
- Homo habilis developed instruments for survival, manufacturing stone utensils, and walked upright.
- Their brain size doubled compared to Australopithecus.
Homo Erectus
- Homo erectus was the first to migrate from Africa to Asia.
- They had a larger brain capacity than Homo habilis, creating more complex stone instruments.
- They walked upright, discovered fire, developed social coexistence, and wore animal skins for protection.
Homo Sapiens
- Homo sapiens, or Modern Man, spread across the land, leaving behind instruments of stone, bone, and ivory.
- They developed painting, sculpture, and had a highly developed brain, enabling creativity, invention, and learning.
- They improved communication with others, using speech and more.
Present-Day Humans
- The final evolutionary stage resulted in physically modern humans, who developed their thinking and abilities.
- Humans evolved from apes to become the most intelligent and extraordinary beings on Earth.
