What is Science?

Did you know that December 7th is letter writing day and from December 4th to December 10th is hand washing awareness week. December 10th is human rights day, December 20th is Hanukkah, December 25 is Christmas, December 26 is Kwanzaa, December 27 is fruitcake day and December 31st is New Years eve. So Happy Holidays is actually more appropriate than Merry Christmas. Why limit the celebrations? And of coarse my Birthday is in December. My birth stone is turquoise and my flower is narcissus.
My education focus for today was science, evolution and DNA.  First off John A. Moore answered the question:
What is science?
Science is a way of knowing by, accumulating data from observations and experiments. Seeking relationships of data with other natural phenomenon. Excluding supernatural explanations and personal wishes. "Science is never complete and each new discovering produces new questions"
He also wrote the book, Science as a way of Knowing.
On evolution I learned that civilization is revving itself into a pathologically short attention span. I also learned the Charles Darwin wrote an autobiography (which I would like to read).  Darwin's friend Thomas H. Huxley said "Science is nothing but trained and organized common sense".
Homo sapiens (humans) ALL came from Africa, therefore there is more diversity in the African people than in anyone else. Animals are also a lot more diverse than humans. Also most people worldwide are lactose intolerant after infancy, which is normal. Some humans have evolved from dairy farmers and they have a genetic mutation that allows them to keep producing lactase as adults and therefore digest milk. I am not from a family of dairy farmers. I didn't expect to hear proof that most people shouldn't drink cow's milk from a lecture on evolution. 
Other human-like people traveled the world before humans did.
Samuel Clemens aka Mark Twain said in1883 "If the Eiffel tower were now representing the world's age the skin of paint on the pinnacle-knob at its summit would represent man's share of that age" and "Man was made at the end of the week's work, when God was tired".
 
DNA stands for Deoxyribonucleic acid.
