A study of terrestrial and marine climate proxies spanning the last 620,000 years in Africa's low latitudes--a timeframe and region important to the evolution of modern humans--finds that the key driver of moisture availability across Africa was likely warming and cooling of the Pacific Ocean paced by changes in solar radiation; this climate process may have in turn governed the distribution of plant and animal species and created favorable conditions for resource-rich regions from which modern humans may have emerged, according to the authors.
