They have learned to survive and evolve in the face of intense global and geographic changes. Amnh.org states: “Like all amphibians, frogs are cold-blooded, meaning their body temperature changes with the temperature of their environment. When temperatures drop, some frogs dig burrows underground or in the mud at the bottom of ponds. They hibernate in these burrows until spring, completely motionless and barely breathing. Without a survival mechanism, these animals would be there and, as I said before, it would have dire consequences. Being able to adapt and survive is an important part of the evolution of species. In front of my pongs, a few meters from the pond, we saw tiny holes that would soon be covered with earth. We also drained the pond during the winter so it wouldn't be frozen all winter. At the bottom, we always saw small burrows dug in the mud. It's amazing that frogs learned to do this to stay alive during the cold
