Summary- The main evolution events that have happened to beluga whales is turning from air breathers to water breathers. This change happened about the time of the rising water temperatures and levels. This forced the beluga whales to swim south for colder waters and to either adapt to the water levels or die. This was the main point of evolution that contributed to their overall success on planet arda after 5 million years.
The speciation event occurred due to the rising water levels and temperatures. This is what forced some of the beluga whales to stay in the increased temperature waters and turn into water breathers. This allows them to dive 100 ft deeper then they used to and allows them to find their prey that lives towards the bottoms of the ocean. As for the remaining air breathers, They migrated south to colder waters not only due to the temperature and water levels but also due to the new species of koala whales that had just migrated to the water where the belugas lived. This increased the survival of the air breathing beluga whales.
The species of water breathing beluga whales main adaption was more blubber and the ability to dive much deeper. They can dive much deeper to find their prey. This at first lead to a increase in the water breathing population. Also their ability to dive kept them away from the koala whales which had also been killing beluga whales. Eventually the prey and food sources of the water breathing whales ran out down in the depths of the ocean so they had to surface more for food. The increase blubber and first helped them a little from the koala whales but eventually the water breathing whales were completely wiped out.
The air breathing beluga whales which is the new and still surviving species has started to mate with toucans. This has occurred to the island of toucanopolis being engulfed with water because fo the rising water temperatures. This has forced for the toucans to live in the waters with the beluga whales. Over time the offspring of these two creatures have made the beluga whale population start to acquire wings. These wings are short and are not a source of flying all the time like regular birds. The main purpose these wings were acquired is due to the the climate down south where it is more cold, the prey of the whales is running short and they can use their wings to fly to where the fish are and swim back. The longest they can fly is 15 minutes.
