Two species look very similar during the earliest stages of development. As they grow and change, they look similar for a very long time until they finally reach a stage where they develop structures unique to each species. We know these species are related due to _________ evidence.

• embryological

• structural

• fossil

• DNA

In a cladogram, the more recent species are at the top. The common ancestor of all the species is at the bottom. This means, as you go from top to bottom on a cladogram, you go further back in________.

• embryology

• DNA

• the fridge

Penguins and Polar Bears both live in cold parts of the planet. They both need to stay warm to survive. To accomplish this, Penguins have thick feathers and Polar Bears have fur. Polar Bear fur and Penguin feathers are different structures with the same function. They are...
