When we get into this field, the extensive and complex biological engineering begins to make me take a step back at the big WOW! factor. Many believe that the biological programming which helps birds to navigate, and plants to photosynthesis can be learnt in all detail if they can learn more on these matters. I'm no scientist, but the fact that such complex programing (biological programming from the start) can be installed in living things makes me wonder if there could be some higher all seeing entity that fashions things so. Some guiding force. I just can't imagine these things coming about by accident and if such things evolve... Well surely evolving from some unseen and undiscovered guiding force or mighty entity.
