Multiple Choice
The concept of evolution by way of natural selection is a central tenet in biology that has been tested in numerous ways by many scientists but is not yet considered a law. Evolution by way of natural selection is most likely which type of concept?
a hypothesis that can be accepted as true based on repeated experimentation with similar results
a likelihood based on the chance that a particular event will or will not occur
a statement of fact that is generally accepted to be true and universal because it has always been observed to be true
