One thing I didn’t see mentioned in this article, that I thought was one of the major motivators for realizing that mitochondria originally came from outside the body, is that mitochondria have their own DNA independent of the cell’s nuclear DNA. But I wasn’t aware that any other animal organelles do (chloroplasts in plants do, and those are also assumed to have originally been an independent bacteria).

A fascinating glimpse of a lost world.
