Presumably their muscle is alot more efficient than ours. A key difference between human and chimpanzee aggression is that humans are found to have a greater inclination than other primates for proactive aggression – meaning aggression that is more thought-out or planned.

Is it an unwanted side effect of intelligence - that our bodies become less important and therefore are able to deteriorate whilst we remain viable? Our fine motor control prevents great feats of strength, but allows us to perform delicate and uniquely human tasks, Walker writes in the April issue of the journal Current Anthropology. Smithsonian Institution. Please refresh the page and try again. Therefore chimps are only stronger if calculate the weight they can lift as a proportion of their body weight. Wellcome Trust. While there are slightly stronger humans, the chimp still has the advantage of durability, attack speed, natural weapons, and sheer primal ferocity. The feet are adapted for grasping, the big toe being opposable. Chimpanzees weigh only 135 pounds max and humans are bigger than them. NY 10036.

Most of you have probably heard that chimps are 5-7 times stronger than humans. Research suggests the difference in strength between the two lies in the muscle performance. The hands have long fingers with short thumbs and flat fingernails.

Other, more impressive figures often pop up when chimp attacks happen. There was a problem. But why? Some hypothesize that this differential reflects underlying differences in muscle mechanics. I'm sure orangutans are stronger than chimpanzees, but they're much slower and less fierce. Rose Eveleth is a writer for Smart News and a producer/designer/ science writer/ animator based in Brooklyn. Walker's hypothesis stems partly from a finding by primatologist Ann MacLarnon, who showed that relative to body mass, chimps have much less gray matter in their spinal cords than humans have.

This composite photograph - an homage to iconic, if outdated, "Evolution of Man" imagery - depicts the measurement of oxygen consumption during walking in quadrupedal and bipedal chimpanzees and in humans. If we see in the animal kingdom, its the size and weight that is the main determinant for strength. Since chimps have fewer motor neurons, each neuron triggers a higher number of muscle fibers and using a muscle becomes more of an all-or-nothing proposition.
