Ancient human species were able to adapt to mosaic landscapes and diverse food sources. This has been reported by the Institute of Basic Sciences.
genus Homo It has evolved over the last 3 million years and has experienced many cycles of climate change. It remains unclear how early human species adapted to climate extremes, ice ages, and changes in vegetation.
To find out exactly how humans evolved, the researchers compiled data from more than 3,000 reliable human fossils and archaeological sites representing six different human species. This is complemented by realistic climate and vegetation modeling covering the last 3 million years.
“This made it possible to find out which biomes favored extinct hominin species. H. ergaster, H. habilis, H. erectus, H. heidelbergensis and H. neanderthalensisas well as our direct ancestors – H. sapiensElke Zeller, one of the study’s authors, said.
It turns out that earlier African groups preferred to live in open environments such as pastures and dry brush piles. Hominids that migrated to Eurasia about 1.8 million years ago, for example H. erectusand then H. heidelbergensis and H. neanderthalensis (Neanderthals) over time developed adaptations to other biomes, including temperate and boreal forests.
“In order to survive in the forest, these groups developed better stone tools and likely learned new social skills,” the authors write. Finally, H. sapiens originated in Africa about 200,000 years ago and quickly became “universal”. Mobile, flexible, and competitive, modern humans’ close ancestors survived, unlike other species, in harsh environments such as deserts and tundra.
Further analysis revealed the accumulation of early humans’ residences in regions with increased biome diversity. “This means that our ancestors loved mosaic landscapes with a wide variety of plant and animal resources in their immediate environment,” the authors summarize.
