New Scientific Model Suggests, Ancient Human Migration, Was Driven by Climate Change.
Business Insider reports that a new scientific model suggests that human migration over the last 2 million years was driven by changes in Earth's climate.
.
According to the model published in the journal 'Nature,' the Earth's shifting climate helped to shape the way that ancient humans lived.

The detailed simulation of the planet's climate history was modeled using South Korea's powerful supercomputer, Aleph.
.
The simulation stretches back to the Pleistocene epoch and looks at 41,000-year cyclical patterns in the planet's climate.
.
The model reportedly incorporates climatic changes that occur in response to minor variations in Earth's orbit.
Business Insider reports that it took over six months for Aleph to make the necessary calculations to create the most comprehensive climate model simulation to date.
The team of researchers mapped the locations of over 3,200 archaeological discoveries of ancient fossils and artifacts left by human ancestors.
.
Even though different groups of archaic humans preferred different climatic environments, their habitats all responded to climate shifts caused by astronomical changes in Earth's axis wobble, tilt, and orbital eccentricity with timescales ranging from 21,000 to 400,000 years.

The simulation suggests that modern-day human species may have emerged following a period of drought in southern Africa and Eurasia.
.
This dry period may have forced our ancient ancestors to adapt an estimated 300,000 years ago.
