Can we go over what she was talking about with evolution? Is it just that since mitochondria and chloroplasts have their own DNA they were likely prokaryotes before? What else should we know evolution-wise without the actual evolution unit?
She talked about fitness a bit, which might come up briefly in genetics (with different traits) but understanding this theory is likely the most important. Does this answer your question?
Yeah, I just do not understand the endosymbiotic theory… how can I understand it better?
