Why do ant carry 5 times there weight?

Hello Pnoyballer! Some things are what they are and we should let them that way because they are for the best. If a apple was 10 times the weight of a man, i think that the man will have the strenght to pick it up, because of evolution and adaptation functions during a very very long time. We all adapt, plants, animals, humans to our necesity

http://en.wikipedia.org/wiki/Square-cube_law Check the part on biomechanics. A larger creature has less muscular strength per unit mass. That is, ants can carry several times their body weight precisely because they're small. A human-sized ant wouldn't even be able to move.
