Some Kemetnui moved east around 2800 BC why and what impact did they have? A new explanation is climate change. Anthropologist Anders Erikkson of Cambridge University in England says the first few hardy humans who left Africa to the East might've gone earlier but couldn't until climate change made it possible!
New paleoclimate research indicates that modern humans left Africa approximately 60,000 years ago due to a change in climate from wet to dry. The climate in northeast Africa during the migration of people from Africa to Eurasia between 70,000 and 55,000 years ago remains unknown. Recent studies reveal that around 70,000 years ago, the climate in the Horn of Africa transitioned from a wet period known as the 'Green Sahara' to an even drier condition than what exists in the region today.
These climate shifts, triggered by the wobble of Earth’s axis, created green corridors between Africa and Eurasia that set the stage for migratory waves of Homo sapiens. John Stewart of Bournemouth University thinks that shifting climate likely moved people around the landscape of what is now Europe and Asia, isolating some populations and caused humans to move in unprecedented numbers.
Ancient human predecessors were closely connected to their surroundings, influencing their living conditions and locations. When faced with environmental changes like drying rivers or diminishing local grasslands and animal populations, how did early humans react? While bones, stone tools, and artifacts offer insights into their appearance and behavior throughout history, uncovering evidence of the habitats they inhabited can be even more challenging. This is particularly true due to the significant alterations caused by changing climates over time.
