Cats have not and will not be domesticated.
You probably have heard of mitochondria (the powerhouse of the cell) and of chloroplasts (gives the leaves green pigment, used in photosynthesis). But did you also know that according to the endosymbiosis hypothesis, the mitochondria & chloroplast were once free-living cells. They were “swallowed” into other larger cells and became a subcomponent. Evidence for this includes the fact that both these structures have their own DNA and can self-replicate.
Mitochondria is the prisoner of the cell
Where there are wolves, there are ravens. Ravens follow wolves around a lot, mostly because they just seem to like them. They aren’t known to follow other predators and they prefer to eat with the wolves instead of alone. Source
ravens get easy food out of the relationship, and wolves get protection; the ravens fly above and alert the wolves to danger. ravens and wolves are also known to play with each other, esp. chasing games. they are both intelligent and playful animals who genuinely enjoy each other’s company. they also understand many of the other’s vocalizations.
