Evolution is the change in gene frequencies over time. Accepting my premise is just knowing the textbook definition. I think what you are trying to describe is "novel fitness increasing mutations" - these won't be detectable for ages as it takes time to spread through a population. Single isolated events matter - All mutations start off in an individual, they then increase or decrease in frequency.
