Across
- 1. Evidence/if species inherited many of the same genes from a common ancestor, then they should have similar body structures and develop in a similar way
- 3. change in species over time that contributes to their survival
- 4. ancestor/an ancestor that is shared by two animals in the past and have evolved into two species
- 7. anatomy/the study of similarities and differences in structures
- 8. record/all known fossils placed in a timeline
- 9. structures/a body parts that were passed from an ancestor that is no longer useful in the present day
Down
- 2. structures/parts of an organism that look similar but have a different ancestor from an organism
- 3. study of the growth and development of offspring from fertilization
- 5. structures/parts of an organism that are similar in origin and structure to another organism
- 6. tree diagram/diagram that shows evolutionary relationships
