Most human athletic abilities have some equivalent in the animal land . For example , the fast humans can reach top speeds that are n’t even half those of cheetah , antelope , and unnumberable other beast , andthat ’s hardly the only areawhere animals can crush our greatest athletes . But there ’s one major elision : throw .
Most species lack the basic anatomy needed to discombobulate a ball , spear , or other missile , but that still leaves our high priest cousin-german . Our closest living evolutionary relative , the chimpanzee , can befuddle no faster than 20 miles per 60 minutes , which is only a one-fifth of the top speeds pass on by some athletes , most notably pitchers in baseball . It was athlete such as those that research worker studied , as they found that college baseball players used their shoulder joint like slingshots , storing elastic energy in the surrounding ligament and tendon before release the ball . That power to stack away energy in the shoulder is what have man ’ supercharged give ability potential .
George Washington University investigator Neil Roach , who led the study , tell that this organic evolution dates back to early hominin mintage like Homo erectus , and this version would have made more complex , throwing - qualified hunting techniques possible . He explains the results of this ancient adjustment to BBC News :
“ achiever at hunt let our ancestor to become part - time carnivores , eating more small calorie - productive meat and fatness and dramatically improving the quality of their diet . This dietary change extend to seismal shifts in our ancestor ’ biology , allowing them to grow larger bodies , larger brains , and to have more baby , and it also did interesting thing to our societal structure . We start to see the ancestry of divisions of labor around that time , where some would be hunting , others would be gathering newfangled food . It probably also allowed us to move to new surround , such as area that did not have vegetation to support us before we had the ability to hound . ”
Harvard ’s Daniel Lieberman add :
“ That ’s not a by - production of evolution for something else , it ’s clearly an adaptation . There were shifts in our anatomy that enable us to throw accurately , so we require to understand better just what those early hunt challenges were . Human hunting is such an gripping problem and the fact that these features all appear by the clip Homo erectus evolve , suggests that hunt may have been a selective force for the ability for throwing . ”
