Theory of Evolution

A grizzly bear survives because he is well-adapted to his environment. When he reproduces he passes on those traits to his offspring. this process is called

• Natural Selection

• Selective Breeding

• Random mutations

• Variations in a species

The Galapagos Islands, a small group of islands off the coast of Ecuador, is home to reptiles such as the giant tortoise and the iguana. The eastern islands are much older than the islands to the west.  Which statement about the origin of these reptiles is best supported by this information?

• The ancestor of each species came from different continents at different times.
• The common ancestors of the reptiles probably came from Equador.
• The common ancestor of each species evolved in Peru and came to the islands at the same time.

The picture shows the members of the Camelidae family. The physical features and the geographical origin of these animals provide evidence that - 

• they live in the same type of environment.
• have slowly evolved to become herbivores.
• have a common ancestor.
• exchanged DNA in the past.
