Evolution Is Based on Evidence

No doubt you have heard of evolution. It's a hotly debated topic right now, and there are some strongly opposing viewpoints on whether it is real or not. Evolution is the idea that all species on Earth are descendants of ancestors that were different from themselves.

This definition is not what comes under fire; rather it's the validity of evolution itself. Evolution is a scientific theory, and when people hear the word 'theory,' they tend to think of an 'idea' or 'generalization.' Basically, something that's not concrete or scientifically founded.

But a scientific theory is very different because it is a thoroughly tested and overwhelmingly accepted explanation of natural phenomena. Because evolution is a scientific theory, it is just as valid as Newton's theory of gravity and Einstein's theory of relativity. You sure don't hear those being questioned!
