Birds Evolved Wings to Keep Them Grounded?
According to this news item from United Press International, Ken Dial, a vertebrate biologist from the University of Montana, has proposed (in a paper published in the journal Nature) that primitive birds first evolved wings to help them stay close to the ground. Dr. Dial developed his hypothesis after studying the movements of young partridges.
