Evolution or intelligent design?
Do you believe in the basic principles of evolution (i.e., natural selection with new traits occurring because of random DNA mutations) or a more Biblical reasoning of species? Do you believe in a more abstract view of intelligent design, (e.g., DNA mutations are not random but a supernatural influence)?
One argument intelligent design advocates use is "irreducible complexity." The idea is some traits are so complex, the would have no use but in their finished form, and the finished form is so complex, it could not arise from a DNA mutation. Some say that's a specious argument, as you might not comprehend the use of a trait in its unfinished form (e.g., the famous bacterial flagellar motor acted as a syringe before a motor).
If you believe in the principles of evolution, what do you suppose the purpose of intelligence was, before fully shaped? What do you think it looked like in its less finished form? What are the first forms of self awareness and do any other species exhibit them? Would it be logical that only one species experimented in the trait of intelligence? Has anyone try to track early forms of self awareness in other species?
