A newborn's brain is adding up to 700 new neural connections per second. This continues with little pruning through age 2. Then massive pruning for the next 4 years, Stabilizes for a while, and then focuses primarily on mild building and pruning through adulthood. This is most likely still going on in old people too. OK So. who knows what capabilities were inherent in those mega connections before pruning? How would we even find out?
