Summary
Everything on earth is at least slightly different in their genetic makeup. Evolution happens when that genetic makeup in species changes over time. An increase in biodiversity in the world happens when a species drifts apart and branches off into two separate species. But there will never be two species on earth with the exact same genes besides twins and clones. Even then we are all different in little ways. Some people read a little too much into this though.

I used tables, graphs, spreadsheets, etc. to display and analyze data in worksheets. We looked at charts to see what species are closer to each other and may have come from a common ancestor. This helps us see how everything came from a few of a certain animal or plant and branched off and evolved.

Everything changes over time whether it's mutation or anything else. When things get separated they change over time in different ways because of their surroundings. It is and almost infinitely small chance that two things will be genetically the same unless they are twins. It is impossible in quantum physics to have two of the same thing in our universe. Everything in the universe just like life on earth came from one thing. The universe and everything came from a big mass that exploded as the big bang and turned into what we know now. All life on earth came from one or two bacteria that over time changed, spread and evolved into everything we know today.
