Evolutionary History End of Unit Assessment

A descendant species is:

• a older population from which two or more newer species descended.

• a related organism from a previous generation

• everything that surrounds an organism

• a more recent species that evolved from an ancestor population.

An adaptive trait is:

• a trait that is a harmful mutation

• a trait that makes it more likely that an individual will survive in a specific environment

• a trait that always shows up randomly and makes an organism stronger

• an adoption

An ancestor is:

• a related organism from a previous generation

• a more recent species that evolved from an ancestor population

• a part of an organism

• Having died out completely and no longer alive anywhere on Earth

Why do cats and giraffes have similar body structures.

• These species are not related

• It was a coincidence, that can't happen

• They share a common ancestor

• They both had the same mother but it was a giraffe

ClownfIsh, Dolphins, and Sharks have similarities and differences in their body structures. What does the information about these structures tell you about the ancestors of these species?

• All three species share an ancestor population, but Sharks and Dolphins share a more recent ancestor population. This is why they share the live birth structure.

• We cannot make observations of ancestor populations from the past. It is impossible to explain ancestors with only the information about the body structures of different species.

• None share an ancestor population because different species cannot share an ancestor population. It is a coincidence that these species have some of the same body structures.

• Dolphins and Sharks share an ancestor population, but they must not share an ancestor with the Clown FIsh because Dolphins and Sharks give live birth, but Clown FIsh lay eggs.

Which of the following situations does NOT explain why one population of descendants look so different from another population of descendants?

• Descendant species adapted to their different environments
