The brutal attack last month by a pet chimpanzee on a Connecticut woman was a stark reminder that chimps are up to four times stronger than humans.
One reason, a new study suggests, is that we pay a price for our fine motor skills.
Humans may lack the strength of chimps — our closest relatives on thetree of evolution — because our nervous systems exert more control over our muscles, says evolutionary biologist Alan Walker, a professor at Penn State University. 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.
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. Spinal gray matter contains large numbers of motor neurons — nerves cells that connect to muscle fibers and regulate muscle movement.

Why would less fine motor skill necessarily mean less strength? It's possible there's a tradeoff but the theory isn't convincing. I think it's possible to have both more motor skill and more strength.
Brainpower
Although the average adult human brain weighs about 1.4 kilograms, only 2 percent of total body weight, it demands 20 percent of our resting metabolic rate (RMR)—the total amount of energy our bodies expend in one very lazy day of no activity. RMR varies from person to person depending on age, gender, size and health. If we assume an average resting metabolic rate of 1,300 calories, then the brain consumes 260 of those calories just to keep things in order. That's 10.8 calories every hour or 0.18 calories each minute. (For comparison's sake, see Harvard's table of calories burned during different activities). With a little math, we can convert that number into a measure of power:
—Resting metabolic rate: 1300 kilocalories, or kcal, the kind used in nutrition
—1,300 kcal over 24 hours = 54.16 kcal per hour = 15.04 gram calories per second
—15.04 gram calories/sec = 62.93 joules/sec = about 63 watts
—20 percent of 63 watts = 12.6 watts
So a typical adult human brain runs on around 12 watts—a fifth of the power required by a standard 60 watt lightbulb. Compared with most other organs, the brain is greedy; pitted against man-made electronics, it is astoundingly efficient. IBM's Watson, the supercomputer that defeated Jeopardy! champions, depends on ninety IBM Power 750 servers, each of which requires around one thousand watts.
