A research team from Arizona State University discovered the oldest known evidence of human's own genus, i.e. Homo. The earliest homo was found at Ledi-Geraru in the lower Awash Valley in Ethiopia. After the disclosure, consideration swung to reproducing the earth of this old human progenitor to comprehend why there and why then.
What is the perfect method for understanding and finding where the ancient ancestors lived? There's a need for re-creating specific environments from millions of years ago for understanding the habitat of the ancestors, such as the earliest homo, in this case. According to Science Daily, animal fossils like proxy time machines are used by the paleoanthropologists for re-creating past environments.
In the event that animal fossils demonstrate perusing on tree leaves, similar to what giraffes and monkeys do, then the scientists realize that the earth was portrayed by woody trees and critical precipitation. In the event that the fossils propose eating on grass, as many antelopes do, then the situations would have been open and arid with grassy plains. In the case of the earliest homo genus, the environment was a grassy beginning, according to the study by the scientists.
Science News Line cited that scientists have found that it was the grassy environment and global cooling, which was responsible for setting the stage for the beginning of the earliest Homo. Scientists conducted a study on eastern African Plio Pleistocene from around 3.5 million years ago to 1.0 million ago after the discovery of Ledi Geraru jaw, for investigating these long-standing hypotheses.
The research study on the environment of earliest homo has been published in the journal Nature Ecology and Evolution. The study has been co-authored by ASU researchers Joshua Robinson, John Rowan, Christopher Campisano and Kaye Reed with University of South Florida researcher Jonathan Wynn. With the help of different habitat proxies, scientists are able for refining the previous ecosystem reconstructions in each basin so that they are able to identify the details for the grassland spreads.
