Att människoapor skulle vara 5-8 gånger starkare än människor är en myt som bygger på dålig forskning av John Bauman på 1920-talet.
Och, NEJ! Schimpanser väger inte 80-90 kilo som vissa självutnämda experter verkar tro..
Citat:
Consider that a large human can bench-press 250 pounds. If the "five to eight times" figure were true, that would make a large chimpanzee capable of bench-pressing 1 ton. It's just the sort of factoid the zoo staff might tell you to keep you from knocking on the glass.
Citat:
But the "five times" figure was refuted 20 years after Bauman's experiments. In 1943, Glen Finch of the Yale primate laboratory rigged an apparatus to test the arm strength of eight captive chimpanzees. An adult male chimp, he found, pulled about the same weight as an adult man. Once he'd corrected the measurement for their smaller body sizes, chimpanzees did turn out to be stronger than humans—but not by a factor of five or anything close to it.
Repeated tests in the 1960s confirmed this basic picture. A chimpanzee had, pound for pound, as much as twice the strength of a human when it came to pulling weights. The apes beat us in leg strength, too, despite our reliance on our legs for locomotion. A 2006 study found that bonobos can jump one-third higher than top-level human athletes, and bonobo legs generate as much force as humans nearly two times heavier.

Jag tänker speciellt på zoo-schimpanser i stil med
