My brain has wrapped around how the physical body of an organism adapts to its environment. I can imagine how it might be programmed to eat and do things within that environment... But, what truly astonishes me is the part where an organism just knows how to do the most impossible things. For humans, myths and legends and stories that are handed down through the generations in hunter gatherer communities, is thought to be the way we 'remember' how to feed, cloth, and live with other humans. But, to have that all on board without communication from the parents.... There are finches - like zebra finches - that learn how to sing (the males) from their fathers. But, even that is amazing.
