Mechanisms for Evolution

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.

• Genetic Drift
• Natural Selection
• Non-random mating
• Mutation

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

• Genetic Drift
• Non-random mating
• Gene flow
• Mutation

During gestation (pregnancy), a developing male pig 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 in the park, a few of them venture 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 because of their ability to cling to rock while resting.

• Adaptation
• Non-random mating
• Gene Flow
• Mutation

Wolves from the Arizona mesa were transferred to the Colorado Rockies after a forest fire destroyed their habitat. They quickly became part of the local pack and had offspring.

7 Wild Mustangs were taken from the prairies of Iowa after a Texan Rancher purchased them and provided them with their own pasture. Those 7 Mustangs eventually became 122.

Logan was born with unique abilities for quick healing and awesome claws that stick out of his fingers.

The chimpanzees have developed an ability to use simple tools, thanks to their opposable thumb. This has allowed them to thrive in their habitat.
