Gaia Theory and All Life is Connected

The concepts of an interconnected earth are intriguing and measurable. As a botanist and microbiologist I have studied symbiotic relations that range from parasitic to symbiotic. Many indigenous people have understood these concepts longer than modern scientists. The Lakota Sioux state: “Mitakuye Oyasin,”which means, “To all of my relations.” It is a prayer of oneness and harmony with all forms of life: people, animals, birds, plants, insects, and even rocks. It is a reminder that we all share a common kinship within the hoop of life. Our bodies are composites of bacteria, and within our cells are remnants of ancient bacterial cells that are now mitochondria. Dr. Lynn Marguelis a famous botanist, and suppoter of James Lovelock Theory of Gaia states: "The only individuals on the planet are bacteria."

Academic Goal: Compare and Contrast Meiosis and Mitosis

Today in Biology we are compared and contrasted sexual and asexual reproduction. (Essential Question 2) and also considered how bio-ethical questions are made. We also considered the immeasurable contributions to science and western medicine by Henrietta Lacks.

Standard V: Essential Questions

  1. What creates genetic variation in sexually reproducing organisms?
  2. Compare and contrast sexual and asexual reproduction.
  3. How do mutations positively and negatively affect a species?
  4. How are bio-ethical decisions made?

Bell Quiz: Access your text book practice test at biologygmh.com and take the Chapter Nine Practice Test.
