From about 2 million BC to about 8,000 BC, there were periodic changes in the climate on earth. The climate fluctuations were alternating between ice ages and warmer periods (interglacials) with about one hundred thousand years between each.  During these interglacials, there was an abundance of rainfall near the equator, and temperate climates were experienced closer the poles. The interglacials gradually grew colder until most of the earth was covered in ice.  Then, the ice age would suddenly reach its end and a new interglacial would take its position, and so the cycle continued.

Climate change was important or early humans because it shaped the way we evolved into what we are today.

Return to History 8 Human Origins Concepts

Climate change was important or early humans because it shaped the way we evolved into what we are today. When the climate changes, we must either adapt to it, or die due to not being versatile enough to live in that environment. Every climate change causes humans to change also, because if they don't, they will most likely die. Climate change also drove early humans all across the globe. When early humans struggled to find food and water in Africa, they migrated into Europe and Asia, because the temperatures were lower there.
