Evidence of Evolution Biology

Why would scientists use the fossil records to help them determine the species of the unknown primate?

• To compare the evolution of its relatives.

• To see if the fossil has the same mass as a jaw of other primates.

• To determine if the fossil has the same number of teeth as a modern primate.

• To identify evolutionary relationships between the unknown and known fossils.

In biology, NATURAL SELECTION is

• organisms that are stronger will hunt and eat other animals

• organisms with more primitive adaptations tend to survive

• when you select a new pet, like a cat or dog

• organisms with better adaptations to their environment tend to survive and produce more offspring

Which of the following statements should Baltazar use to support his scientific explanation?

• I have shared my thoughts with other scientists, and they seem to agree with my explanation.

• Based on my knowledge and experience at the Natural History museum and the age of this bone, I would argue that it belonged to a flying dinosaur.

• After reviewing our results, comparing it to the research that has been conducted by other scientists, the evidence supports the possibility that the bone belonged to a flying dinosaur.

• In my observation, I noticed that the bone was hollow. I remember learning in college that birds have hollow bones, and considering the age of the bone I believe that the fossibelong to a flying dinosaur.
