If you're claiming that humans are born with more data than the six gigabits of data encoded in DNA, then how do you think the extra data is passed to the next generation?
Can we do better than evolution? Probably; evolution is a fairly brute force search approach and we are pretty clever monkeys. After all, we have made multiple orders of magnitude improvements in the state of the art of computations per watt in just a few decades. Can we do MUCH better than evolution at finding efficient intelligences? Maybe, maybe not.
