Evolution Review

A few deer wander out of their native woods into a completely new park where no deer had ever been before. They go on to create an entirely new population.

Yellow toucan birds seek out one another to make babies together and tend to avoid the green toucan birds.

During gestation (pregnancy), a developing male panda had a change in his genetic code. The result was that he was able to walk and do karate.

Five hundred years after the deer had established a flourishing population (a population that is doing really well) in the park, a few of them move back to their original woods and have babies with the deer there.

Bats are common in Texas, especially in rocky regions. Bats with longer hang claws have demonstrated higher fitness (more survival) because of their ability to cling to rock while resting.

A group of wolves from the Arizona were moved to the Colorado Rockies after a forest fire destroyed their habitat. They quickly became part of the local pack of wolves and had offspring.
