Spirit Animal

During the era of space colonization, Earth sent an experimental colony to tour space until they found a plant similar to Earth that was uninhabited by an intelligent species. 700 years later, the humans happened upon a planet that they thought was uninhabited, but the aliens hid themselves among the dense forests and disguised themselves.
The aliens then noticed something peculiar about these humans, that some of them represented the characteristics of animals. The aliens, obsessed with the possibility of turning these humans into those animals, began human experimentation. Creating a whole cut off colony from the rest of their planet and species, the aliens kidnapped a number of humans and separated them into villages based on their animals.
Years have passed, but have these Aliens succeeded?
