How many billion years would evolution of human brain take?
It takes billions of years *FROM THE FIRST LIVING CELLS* to the human brain. Meanwhile, other single-celled organisms (like E. coli) are also evolving. So why on earth do you think that the evolution of E. coli must occur first, and “then” another billions of years to “replicate and reproduce”, and “then” the evolution of neurons, and “then” the mutations to start wiring up individual neurons into a fully “perfectly completely formed brain.” And then you just add up all those billions of years as if evolution has to evolve one type of cell to completion before even *beginning* another? This is an absolutely *bizarre* concept of evolution! No wonder you think a “smart aleck” needs to defend it. —– @Chrisizkool —– >”How can a human brain be made if it needs to be almost perfect to function. ” That’s an argument against *embryological development*, not evolution! Think, man, think! If your argument were valid, then NO brain … human, chimp, sparrow, or goldfish … could be “made”
