Australopithecus
Lived 4.5 million years ago, first Hominid. Central Africa (modern day Ethiopia.) Lived in forests, mainly in trees. Start of evolutionary chain. -
Period: 200,000 BCE to 8000 BCE
Paleolithic Age
Old Stone Age. Lasted from around 2.5 million years ago to around 10,000 years ago. We lived in groups 20 to 30, we were nomadic, and we were hunters and gatherers. This age died off because we settled down -
199,999 BCE
Invention of Fire
While when fire was first used is debated, early evidence suggests around 200,000 to 400,000 years ago. Fire allowed human expansion and virtually human life. -
199,998 BCE
Homo Habilis
Lived 2.5 million years ago, still in central Africa. They were the first tool makers, those tools were simple and made out of stone. They had larger brains than their Australopithecus ancestor. -
199,997 BCE
Hand Stone Axe
The hand stone axe was developed approximately 2 million years ago. This tool allowed our early ancestors to complete tasks more efficiently. -
199,800 BCE
Homo Erectus
The Homo Erectus lived approximately 1.8 million years ago. This ancestor of ours was the first species to stand erect, bipedal. This was also the first group of our ancestors to leave central Africa. -
199,700 BCE
Homo Sapiens
They lived approximately 200,000 years ago. They replaced all other hominids. There were two groups: Neanderthals and Homo Sapien Sapiens. The former was more brute, but less intelligent. The latter were smarter, built for long distance running, and used language and collective learning to surivive. They expanded on tools that were previously made, and made them smarter. -
120,000 BCE
Climate Change
One of the reasons for migration was natural climate shifts and changes. When climate changed, early humans had to adapt or find an area more suitable for their needs. Many did the latter, which led to migration from Africa -
113,000 BCE
Last Ice Age
The Last Ice Age was a major migration factor that occurred between 115,000 – 11,700 years ago. This Ice Age kept many people locked out of much of the northern hemisphere. -
75,000 BCE
Mount Toba Catastrophe
This catastrophe led to the near extinction of the human race. This even forced the humans to adapt to the new environment, and spread out to further collect resources. -
20,000 BCE
Bering Land Bridge
The Bering Land Bridge (connecting modern day Alaska and Russia) Is the most widely accepted answer to how people migrated to the Americans. This land bridge allowed for people to easily move to the America’s, and resulted in populations in the America’s. -
15,000 BCE
Domestication of Dogs
Domestication of dogs was important for human expansion and evolution because it allowed for us to better hunt our food. -
10,000 BCE
Founding of Agriculture.
Agricultural development led from the fertile lands that were available, and the invention of many new tools. Agriculture allowed humans to settle down, and gave humans access to more food and more energy. Ultimately, as Khan Academy puts it, led to further complexity of the human condition. -
9000 BCE
Founding of Jericho
Jericho, Palestine was the first known city established in the entire world. This city showed that people were starting to settle down, focus on agriculture, the emergence of a social hierarchy, over abundance of food, and more. The city of Jericho was walled in, showing that battle took place for resources. -
9000 BCE
Creation of Social Hierarchy
During the founding of Jericho, we saw the risings of the first social hierarchy. Power dominated from those with more abundance of supplies. Ultimately, this stemmed from the overabundance of resources that came with discontinuing nomadic lifestyles.
