Evolution is the change over time in the proportion of individual organisms differing in one or more inherited traits. Evolution happens when there is a variation of inherited traits within a population. I think that from this, Evolution is a theory because it is not guaranteed to happen such as laws happen all the time. Theories are predictions on what will happen and laws are what will happen. Evolution will not always happen it is more a prediction.
No. It's a Scientific THEORY because it's backed up by experimentally observed facts of nature (scientific laws). A scientific theory and a layman's theory are two different things. The first means there's a lot of data collected to back it up, the second is more akin to a scientific hypothesis (an educated guess).
