U7_Evolution Notes

Life on Earth developed from non-living matter spontaneously.

Life on Earth has remained unchanged since its beginning.

Life on Earth developed from preexisting life over time.

Life on Earth is a result of individual creation events for each species.

By changing their genetic makeup in a single generation.

By moving to different environments to avoid adaptation.

By physically adapting to their environment over many generations.

By remaining static to preserve their original form.

Genetic analysis (DNA)

Because they look similar and evolved to do the same job, but evolved independently.

Because they have the same pattern of bones inside the wings.

Because they were inherited from a common ancestor.

Because they are vestigial structures that have reduced in size.

Whales have always been aquatic animals without the need for legs.

Whales have a vestigial pelvis as a result of convergent evolution.

Whales have a vestigial pelvis because they evolved from a common ancestor with legs.

Whales have a vestigial pelvis because they are starting to evolve legs.
