BUZAN, SOUTH KOREA – In a controversial new study, researchers led by climate physicist and oceanographer Axel Timmerman of Busan National University evaluated data from known fossil and archaeological sites of hominids in light of a computer simulation of possible climatic and local conditions. Africa, Asia, and Europe over two million years, according to a Science News report. The study suggests that Homo erectus, Homo heidelbergensis and Homo sapiens were able to adapt to a diverse range of temperatures, rainfall levels and plant growth while migrating from Africa and unfamiliar environments. The climate model shows that these migrations coincide with the warmer climate changes that occur every 20,000 to 100,000 years due to variations in the Earth’s orbit and the inclination of its axis. Travel, Timmerman said, stimulates brain growth and cultural innovation. In this scenario, he added, H. heidelbergensis may have given rise to the Denisovans in Eurasia about 430,000 years ago, while recurring ice ages in Europe led to the evolution of Neanderthals between 400,000 and 300,000 years ago. Timmerman also suggests that H. sapiens appeared in the harsh conditions of South Africa between 310,000 and 200,000 years ago, then modern humans were able to adapt to the hot and dry climate found in Northeast Africa and the Arabian Peninsula.
