Even though amoeba, paramecium, and spirogyra are quite different, they are all often classified in the same group, Protista because this group holds various types of eukaryotic organisms that are heterotrophic and unicellular.
This type of classification is not based on evolutionary and genetic similarities, but only on the properties of being unicellular, so there are many vastly different organisms in this group.
Evolution is what you might call, traits that is inherited over generation to the next. An evolution is when there is a change within the genepool and it beneficial to survival. Take a giraffe for example. Back then, they had short necks and it had eat from plants on the ground. Though from generations later when they learnt that food grows on trees and stretched there necks to reach for, they now can eat from trees without a problem. Hope this helps you better understand what evolution is.
