Ants

In response to Justine - full post here

Just for the record, I would like to point out an exaggeration. Ants can, at most, lift approximately fifty times their weight. The reason why human cannot do this can be explain as such: Mass increases as a cube of length, while muscle mass increases as the a square of length. This means that if a person were to grow 10 times taller, they would be 1,000 times heavier but only 100 times stronger. As such, more of the individual's muscles must work on holding up the heavier mass. Creature A, weighing 1 ounce, would have an easier time lifting 2 ounces (twice its weight), than a 100 pound creature would have lifting 200 lbs. Despite the proportion of 2:1 in both of these cases, the latter still has to lift less weight, as one hundred pounds is 1600 times heavier than one ounce.
