Massive supernova explosion could have made humans walk upright, study says | The Independent
Cosmic particles from these supernovae bombarded Earth's surface at such excessive stages that they triggered worldwide woodland fires, researchers from the university of Kansas endorse. This brought about the creation of huge swathes of savannahs in places that could previously have been forested. Early hominins in northeast Africa needed to learn to walk on two legs to move these huge regions, consistent with the examine, posted in the journal of Geology.
