Such environments were significantly preferred by early human beings, according to a brand-new research study published in the journal Science by a group of researchers from South Korea and Italy. According to the new Science study, adaptation played a key function in the geographic expansion of our genus Homo. When further looking into the favored landscape characteristics, the scientists found a substantial clustering of early human occupation sites in regions with increased biome variety. “What that suggests is that our human forefathers had a taste for mosaic landscapes, with a great range of plant and animal resources in close distance”, stated Prof. Axel Timmermann, co-author of the study and Director of the IBS Center for Climate Physics in South Korea. The outcomes indicate that environment diversity played a key role in human development.
To evaluate these essential hypotheses on human evolution and adaptation quantitively, the research team utilized a collection of more than 3 thousand well-dated human fossil specimens and archeological sites, representing six various human species, in mix with reasonable climate and plants model simulations, covering the past 3 million years. The scientists focused their analysis on biomes– geographic areas which are identified by comparable environments, plants, and animal neighborhoods (e.g., jungle, tundra, or savannah).
” For the archeological and anthropological sites and corresponding ages, we extracted the local biome types from our climate-driven greenery model. This exposed which biomes were preferred by the extinct hominin species H. ergaster, H. habilis, H. erectus, H. heidelbergensis, and H. neanderthalensis and by our direct forefathers — H. sapiens.”, stated Elke Zeller, a Ph.D. student from the IBS Center for Climate Physics at Pusan National University, South Korea, and lead author of the study.

Science 2020. According to their analysis, the researchers found that earlier African groups preferred to live in open environments, such as grassland and dry shrubland. “To endure as forest-dwellers, these groups established more innovative stone tools and likely also social skills”, said Prof. Pasquale Raia, from the Università di Napoli Federico II, Italy, co-author of the study.
When even more checking out the favored landscape characteristics, the scientists found a considerable clustering of early human profession sites in areas with increased biome diversity. “What that means is that our human forefathers had a preference for mosaic landscapes, with a great variety of plant and animal resources in close distance”, stated Prof. Axel Timmermann, co-author of the research study and Director of the IBS Center for Climate Physics in South Korea. The results indicate that community diversity played a crucial role in human development.
The authors showed this preference for mosaic landscapes for the very first time on continental scales and propose a new Diversity Selection Hypothesis: Homo species, and H. sapiens, in particular, were distinctively equipped to exploit heterogeneous biomes.
” Our analysis reveals the important value of landscape and plant diversity as a selective element for people and as a potential chauffeur for socio-cultural developments” includes Elke Zeller. Illuminating how vegetation shifts have shaped human nourishment, the new Science study offers an extraordinary view into human prehistory and survival techniques.
The environment and greenery model simulations, which cover the Earths history of the previous 3 million years, were conducted on one of South Koreas fastest science supercomputers called Aleph. “Supercomputing is now emerging as an essential tool in evolutionary biology and sociology,” said Axel Timmermann.

New research carried out by an international group, published in the journal Science, reveals that early human species can adjusting to a range of landscapes and food resources. This flexibility would have strengthened our forefathers strength versus historic climate changes.
Our genus Homo progressed over the previous 3 million years– a duration of increasing warm/cold environment changes. The secret of how early human types adapted to these heightened environment extremes, ice ages, and sweeping changes in landscapes and plants continues to baffle researchers.
Did our forefathers get used to local environmental changes gradually, or did they seek out more stable environments with diverse food resources? Was our human evolution influenced more by temporal modifications in climate, or by the spatial character of the environment?
