... evolution is not only a theory, it's also a fact. The key to understanding evolution is to recognize how it can be both:
As a fact: Evolution is simply genetic changes occurring through time in a group of individuals (a population, a species, and so on). Scientists know that these changes occur. They can see the changes, measure them; in many instances, figure out when they happened.
As a theory: Evolutionary theory seeks to explain what's responsible for the evolutionary process - in other words, what causes these changes. What scientists know today is that natural selection and genetic drift are two key forces driving these changes."

Excellent quote and I agree!
ReplyDeleteThanks Madilyn. I love this dummy book!
DeleteYes, the controversy of poor old Charles Darwin rages on. Hard to believe but true. 1/4 of all UK undergrads currently say they believe in creationism. Science may not be perfect (something the scientific community knows well), but it is absolutely the best we have. Without it, superstition and ignorance rule.
