A fruit fly has no meaningful learned intelligence yet is more capable than any trained neural net. It’s just a small bundle of nerves laid out according to the model encoded in their DNA. It was trained through millions of years of genetic algorithms, and is fully encoded in the DNA, along with the entire ability to specify the entire physical structure of its body. Why is it surprising our brain has instinctual ability encoded in its structure stemming from our DNA, evolved over the history of life?
