A history of my animus dreaming,waking

In a recent episode of the TV series Star Trek: The Next Generation, Captain Jean-Luc Picard and the crew of the starship Enterprise land surreptitiously on a distant planet. When they are discovered by the humanoid inhabitants, who have webbed feet and toes and a raised ridge on their foreheads, the human invaders explain that their mission is to assist planetary cultures like theirs when they are ready to begin space travel.
