BY8 Cladograms reveal evolutionary links

So originally, I thought evolution was when a creature evolves to adapt to an environment which holds different dangers that they are not used to so their body changes so they can handle the pressure in their environment. So, the thing I added to it was about how everything comes from one common descent, as in one singular being, and if I had to use a cladogram as an example, of one of the branches represented extinction and one of them represented creatures that are still developing.
