Last common ancestors are hypothetical organisms, its near impossible to know which organism was the last common ancestor. evolution is like stairs with millions of steps, steps represent each organism, you can't exatcly point to the organism where one species ended because its a very slow process. steps are just way too similar to each other. its very complicated so you can ask if there's anything you didnt understand
