Species: a group of organisms that are closely related and can mate to produce fertile offspring

Evolution: the process in which inherited characteristics within a population change over generations such that new species sometimes arise

Fossil: the trace or remains of an organism that lived long ago, most commonly preserved in sedimentary rock

fossil record: a historical sequence of life indicated by fossils found in layers of earths crust

1: Members of the same species can mate with one another to produce offspring

2: An adaptation helps an organism survive.

3: When populations change over time, evolution has occurred.

Understanding Key Ideas

4: A

5: Bones have moved, changed, and more making it seem that an organism's hand has shaped differently

6: To show how large and different the ancestors looked.

Critical Thinking

7: They are bigger

8: just count this wrong I'm not doing that

Interpreting Graphics

9: yeah this one too why not.

Selective breeding: the human practice of breeding animals or plants that have certain desired traits

Natural selection: the process by which individuals that are better adapted to their invironment survive and reproduce more successfully than less well adapted individuals do; a theory to explain the mechanism of evolution

2: Natural selection and selective breeding are somewhat alike, selective breeding for the strongest, fastest, and smartest. These are essential traits for Natural selection

3: D

4: A theory on how some animals seem alike, but different at the same time

6: Birth to continue a legacy, differentiating parents from offspring, Fight or die, and offspring surviving to somewhat have characteristics of their parents.

7: Not knowing HOW they inherited traits

8: 5 I guess

9: food, environment, and traits

10: To withstand heat and volcanoes somehow, if one exploded others would be near. And since an island doesn't have enough food they would be small and fight for survival.]
