Foresight is an interesting word to bring about into a discussion of evolution and evolutionary biology. Any living being with a brain, can be divided into its body and its mind. One is a physical entity and the other is non-physical and exists only if the physical entity it thrives on is living. (I could say that the mind/thought is a parasite of the brain

) Anyway, it is the mind which can even attempt foresight -- to see ahead requires thinking, planning and memory. The basic thesis from evolution of the body is that it doesn't have foresight, hence the weird structures and older baggage in the architecture of the bodies of all beings.
