LS 4.2

If an orangutan, a human, and a whale evolved from a common ancestor, what most likely can be concluded?

• They will live in similar areas

• They will be in the same biological classification

• They will share similar anatomical structures

• They will have a similar diet

Scientists compare the limbs of organisms to look for evidence of common ancestry. These limbs provide evidence of common ancestry because they -

• perform the same function

• are the same size

• have the same basic structure

• are parts of the same animal

The similarities among early stages of the embryos provide evidence that -

• these organisms evolved from a common ancestor

• the organisms all retained their gills and tails

• the organisms belong to the same species

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.

Which statement can be best supported by the pictures of the embryos.

• Chickens are more closely related to tortoises than rabbits are.

• Rabbits, chickens, tortoises, and fish are all equally related to each another.

• Fish do NOT share a common ancestor with other vertebrates.

• Fish and chicken are the least closely related.

What is a homologous structure?

• having a body part that has no known function

• similar structures in more than one organism because they evolved from a common ancestor

• a structure that evolved to help an organism survive in their environment

• similar structures that evolved independently in two living organisms to serve the same purpose

What evidence do similarities between fossil bones and modern organisms provide?

• species that face similar environmental pressure will develop similar traits.

• homologous structures are evidence that the two species are related or shared a common ancestor

• natural selection

• adaptive structures help organisms survive in their habitat

What is the advantage of having different shaped beaks?

• To look different from other species.

• To be able to eat the food readily available in the environment.

• To protect itself against predators.

• To protect itself against prey.

What has the study of fossils allowed scientists to do?

• study present ocean temperatures at different depths

• describe past environments and the history of life

• predict which organisms will become extinct in the future
