Reptiles

Reptiles are interesting creatures. They have some of the oldest families on the earth. One could say that they have more of a claim to this planet than us. We have more agency though.

There are tales of times when it was not so. Dinosaurs is a part of this. When the climate changed (possibly due to a pole shift) most of the reptiles left. The others died off, or were killed.

What sort of experiment is this planet actually for?

This planet can be seen as an experiment in the binary. It's the negotiation of two polar opposites, or at least two forces that chose to be polar opposites.
