Sabotab

Hello everyone, im not a scientist, not even close, but i had to find a forum of which i could post my question. Im not here to second guess Darwin's theories, yet i do find it disturbing: The famous evolution picture (monkey to man) has a couple species in between, where are they? what happened to them? Now its only the monkey and the man, also, if the whole theory is true, how come monkeys stopped evolving into the "in between" species? Im grateful for any feedback. Have a good one.
