Natural Wonders & Evolution: grizzly bear hibernation (Evolution)

DAVID: How did this evolve by chance. There is no way a bear could try going to sleep for months and survive without preparation by a designer:

QUOTE: "Grizzly bears spend many months in hibernation, but their muscles do not suffer from the lack of movement."

DAVID: Non-essential amino acids are an interesting observation. They must have been designed just for this very special process and therefore are required to be in these bears. There are 20 essential amino acids that are left-handed and must be present for life to exist. It is not known if these special proteins exist anywhere else. The grizzly DNA requires this behavior to happen each year. Bears did not just decide to require this process. Note my bold: "Nature perfected a way". Pure Darwin illogical thinking. How about a designer!

Thank you for yet another fascinating “wonder”. Of course the argument applies to all creatures that hibernate, and to all creatures that adapt successfully to difficult conditions. And of course these adaptations do not develop by chance, and of course the bear didn’t “decide to require this process.” The conditions required this process, and we know that countless species have died out when they are unable to cope with new conditions. “Nature perfected a way” suggests to me that there is a mechanism at work (possibly designed by your God) which enables SOME species to survive while others go extinct. It is what Shapiro calls “natural genetic engineering” carried out by intelligent cells. It’s just a theory, but it removes the need for your God to preprogramme or dabble every single adaptation in every single species that survives (while 90% or so die out), in anticipation of every environmental change, whether local or global, for 3.X thousand million years, all for the purpose of designing one species. Either the cells work out a solution, or the organism dies – hence the long, long history of changing life forms. So much simpler and so much more logical than your theory. Ockham would rejoice.
