Help me i dont understand
Evolution can be biological as well as cultural, essentially it implies to gradual change in biological organisms (biological evolution) or change in food habits, outfits/life-style, ideas (cultural evolution).
Revolution is essentially revolt or rebellion and it is drastic, that is completely antagonistic to slow evolution.
Revolution could be the outcome of oppression, it may or may not happen. In contrast, evolution is
a constant phenomenon in biological system that responds to changing environment, severe environmental stress can have a profound impact on evolution, however, it is a constant process that is mostly gradual.
Hope this helps.
