Presentation Transcript

  1. Review-What is the difference between pure science and technology? New technology is furthering our understanding of evolution.

  2. 7. Biochemistry-Molecular and genetic evidence support fossil and anatomical evidence called molecular clocks • Two closely-related organisms will have similar DNA and RNA sequences. • Genes and proteins with matching sequences.

  3. 8. Physiological Adaptations • Changes in an organisms metabolic processes that help survival Bacterial resistance to disease Pesticide resistance in plants

  4. Chromosome comparisons

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

  6. Breeding behaviors • Month of year • Calls

  7. control the development of specific structures, cell differentiation in embryonic stages or larval stages • Ex. Eye spots of marine worm • Protein comparisons, or molecular fingerprinting reveals similarities among cell types of different organisms. • Homeobox or Hox genes indicate a very distant common ancestor.

  8. 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.
