Why is a scientific theory?

Because it is based on a massive body of evidence that provides correct predictions of what we should find.


For example, humans have 46 chromosomes and the "great" apes (chimpanzees, gorillas, and orangutans) have 48. Why is this?

It was predicted that since we were the outlier, that we had a chromosome that fused. We started searching our genome and found teleomeres in the middle of chromosome #2. What does this mean? Well, since teleomeres are only found on the ends of chromosomes, this provided the evidence that our chromosomes had a head to head fusion.

Upon more research it was found that the genes on our Chromosome #2 (the fused one) directly correlated with the genes on two of the chromosomes of the "great" apes.


It has also been used to find specific fossils by predicting where the transitional species would be AND and what depth in the geological column. This is how we found a species of animal that was an ancestor of whales which lived both on land and in the water.


It's these kinds of correct, testable predictions that make evolution scientific theory.
