6. What does Kammerer do to experiment with adaptation?
He set up an aquarium for the midwife toads and the made it very hot. He put water and dry land into the aquarium and left the temperature very hot; forcing the toads to go into the water.
7. What happened in Kammerer’s experiment? How long did it take Kammerer to see interesting results? What would Darwinian evolution say about that?
