People complain of back and feet problems constantly, and the
American Association for the Advancement of Science has announced that his may
be because of evolution. They said that humans are the only mammals that have
these problems; scoliosis, an abnormally curved spine, is only seen in humans.
Archeologists have said that skeletons dating from 1.5- 3 million years ago
also show evidence of back problems. Walking upright and the need to carry
heavy loads are associated with humans’ unique back problems. Jeremy DeSilva,
anthropologist at Boston University, said “Likewise, the human foot’s structure
has evolved in a way that also causes problems.” He believes that the arch in
people’s feet is what causes many foot problems, but that people have them to
assist in running and absorb energy when walking. This proves that evolution is
not immune from imperfections.
