Last Sunday I chanced upon a National Geographic feature about caterpillars, elephants and the emperor penguin from which I learned the following:
1. In the transformation of caterpillar to moth (or butterfly,) two different sets of DNA are operational. Once the caterpillar is ready for metamorphosis it's hormones activate the butterfly DNA. The caterpillar "dies" in the process while in the cocoon to give way to a different being.
2. Before it can even fly & feed the newly emerged butterfly must stretch its proboscis so that the two divided parts lock in like a zipper. It's crumpled wings must also stretch to allow oxygen to pass thru (since the butterfly doesn't have any lungs.)
3. The male emperor penguin takes care of the newly hatched egg,keeping it warm by balanceing the egg on it's toes and sitting on it for about 6 weeks. Meanwhile,the female goes to sea and hunts for fish which it will feed the chick when it hatches. The males huddle during cold days to keep their bodies and eggs warm and because they don't feed all this time they start to grow thinner. Just in time, the chicks hatch and the mother penguin has to be back by that time because the male might,in his hunger, go out and feed,leaving the chick to die from the cold. Once the females arrive they give out a call which only their partners recognize! When they finally reunite, the male passes the chick to the mother quickly so that she can feed it with regurgitated fish. The male then leaves to feed.
4. The elephant mother carries her baby for 22 months. The reason for this long period is that the brain of the baby elephant must be fully developed before it can come out.
5. Baby alligators must feed themselves once they hatch because like all other reptiles they don't rely on mother to feed them.
Whenever I watch fascinating things like these I can only believe that there is a God!
