Ok, we all know normal body temperature is around 98 degrees. Then how come when it's 98 degrees outside, it feels uncomfortably hot. It seems like it should feel just right.

My understanding is... Chaos varies hairiness across a species, and it also varies the weather. An ice age kills the less hairy, and the more hairy multiply. The word "Evolving" means unrolling, like petals or a map. I don't see any analogy. Perhaps over long timescales one could argue for the unfolding of inevitable characteristics (like eyes arising in both insects and mammls) but the evidence does not suggest any pre-destined (rolled-up) ideas. Maybe the word could be replaced with something less confusing?

I understand that no scientist should claim to have all the answers. To think so would be arrogant, at the least. Nonetheless, do Evolutionists assume there must have been some begining to all, (wheather or not this "begining" had life)?

If evolutionists do not believe in an ultimate begining, they must believe in an "eternal-before", correct? If evolutionists do believe in an ultimate begining, then what is the source of that begining, (be it alive or not)? If evolutionists are undecided in this topic, then science would demand they had an open mind to any possibilities, Would it not?

My apologies for the multiple questions. I have just been inquiring more and more about science and its theories. I know about the many books, but it will take me time to read them all!!

Thank you. I appreciate any and all answers.
