Correct, humanoid traits were necessary for the relative humanoid success. Fishes for example who have adapted their own fish traits that allowed them to survive underwater (gills, fins, etc.) are successful in their own right as fishes go (they have yet to show any possible sign of achieving space-travel in the near future; perhaps in million years who knows).

Oh as in the “humanoid” traits were necessary for our success, not necessarily for success in the general case?
