Exactly and the languages don't express that practice. We get design patterns / DI and maxims like composition over inheritance. Our languages still make it easier to inherit than to compose despite all that. Plus, my wider point was that in the real world, which is the inspiration for OOP, the taxonomy is artificial and placed onto an object. The taxonomy isn't an inherent part of the object (i.e Dog extends Canidae). The taxonomy is given to an object based on its composition separately i.e a dog is a dog because of some property x, y and z and just so happens that X, y are what makes Canid a Canid and X is what makes a carnivore a carnivore.
