Do you believe that forks are evolved from spoons?
Forks were always forks.
They are much too complex in structure to have sprung from the evolutionary loins of the simple spoon.
Contrary to popular opinion, I believe that spoons evolved from forks as the hideously deformed and misbegotten offspring resulting from the illicit matings between forks and knives. It makes me cringe to think of it.
See the photos of the bizarre mating dance of the knife and fork below, which was captured by a very brave cinematographer, if you need further evidence of this.
