| A | B |
| Most fossils are found in | SEDEMENTARY ROCK |
| (Because most organism do not become fossils) Fossil records are | INCOMPLETE (can't tell us about every organism that ever lived) |
| Characteristics that a person develops or aquires during their life such as muscles from working out are called | AQUIRED CHARACTERISTICS |
| Structures that are the similiar (same) in function (job) and structure (form and shape) are called | HOMOLOGOUS STRUCTURES |
| A structure such as the appendix that serves no purpose anymore is called a | VESTIGIAL STRUCTURE |
| The study of embryos and their development is called | EMBRYOLOGY |
| Embryology shows that fish and human embryos both have tails. This shows they had common.... | ANCESTORS, GIVING EVIDENCE FOR EVOLUTION. |
| Bat wings and human arms are similiar in structure and function (homologous). This | SUGGESTS THEY HAD COMMON ANCESTERS, GIVING EVIDENCE FOR EVOLUTION. |
