New Scientific Model Suggests, Ancient Human Migration, Was Driven by Climate Change.<br />Business Insider reports that a new scientific model <br />suggests that human migration over the last 2 million <br />years was driven by changes in Earth's climate. .<br />According to the model published in the journal <br />'Nature,' the Earth's shifting climate helped <br />to shape the way that ancient humans lived. .<br />According to the model published in the journal <br />'Nature,' the Earth's shifting climate helped <br />to shape the way that ancient humans lived. .<br />The detailed simulation of the planet's<br />climate history was modeled using <br />South Korea's powerful supercomputer, Aleph. .<br />The simulation stretches back to the <br />Pleistocene epoch and looks at 41,000-year <br />cyclical patterns in the planet's climate. .<br />The model reportedly incorporates <br />climatic changes that occur in response <br />to minor variations in Earth's orbit.<br />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.<br />The team of researchers mapped the locations of over 3,200 archaeological discoveries of ancient fossils and artifacts left by human ancestors. .<br />Even though different groups of archaic <br />humans preferred different climatic <br />environments, their habitats all responded <br />to climate shifts caused by astronomical <br />changes in Earth's axis wobble, tilt, and <br />orbital eccentricity with timescales <br />ranging from 21,000 to 400,000 years. , Axel Timmermann, climate physicist at Pusan National University in South Korea, via Business Insider.<br />The simulation suggests that modern-day human <br />species may have emerged following a period <br />of drought in southern Africa and Eurasia. .<br />This dry period may have forced <br />our ancient ancestors to adapt <br />an estimated 300,000 years ago.
