Considering, for those of us who breathe oxygen, our mitochondria are actually invaders of an originally anaerobic cell. This event occurred many millions of years ago. However, it probably took place over eons of time. Many invaded cells suffered and died before the right combination of conditions occurred for the mating to be stable.
Everything wants to merge.

Every living thing has at least one parasite that lives inside or on it, and many, including humans, have far more. Leopard frogs may harbor a dozen species of parasites, including nematodes in their ears, filarial worms in their veins, and flukes in their kidneys, bladders, and intestines. One species of Mexican parrot carries 30 different species of mites on its feathers alone. Often the parasites themselves have parasites, and some of those parasites have parasites of their own.
Scientists have no idea of the exact number of species of parasites, but they do know one fact: Parasites make up the majority of species on Earth. Parasites can take the form of animals, including insects, flatworms, and crustaceans, as well as protozoa, fungi, plants, and viruses and bacteria. By one estimate, parasites may outnumber free-living species four to one. Indeed, the study of life is, for the most part, parasitology.
Great FIND Sammy...................THanks and yes is it interesting and TRUE!!
