  1. KEY CONCEPT New technology is furthering our understanding of evolution.

  2. Fossils provide a record of evolution. • Paleontology is the study of fossils or extinct organisms.

  3. Paleontology provides evidence to support evolution.

  4. Molecular and genetic evidence support fossil and anatomical evidence. • Two closely-related organisms will have similar DNA sequences.

  5. no longer function • carried along with functional DNA • can be clues to a common ancestor • Pseudogenes are sequences providing evidence of evolution.

  6. control the development of specific structures • found in many organisms • Protein comparisons, or molecular fingerprinting reveals similarities among cell types of different organisms. • Hox genes indicate a very distant common ancestor.

  7. Evolution unites all fields of biology. • Scientist from any fields contribute to the understanding of evolution. • The basic principles of evolution are used in many scientific fields.
