  1. 1. structures/a body parts that were passed from an ancestor that is no longer useful in the present day
  2. 3. anatomy/the study of similarities and differences in structures
  3. 4. structures/parts of an organism that are similar in origin and structure to another organism
  4. 5. change in species over time that contributes to their survival
  5. 8. tree diagram/diagram that shows evolutionary relationships
  6. 9. record/all known fossils placed in a timeline

  1. 2. study of the growth and development of offspring from fertilization
  2. 3. ancestor/an ancestor that is shared by two animals in the past and have evolved into two species
  3. 6. structures/parts of an organism that look similar but have a different ancestor from an organism
  4. 7. 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
