  1. Evolution A look at the theory of evolution and Natural Selection

  2. How Did Life Begin? • Extra terrestrial origin • Life originated from other planets outside our solar system

  3. How Did Life Begin? • Creation • Life was put here by divine forces • Cannot be explained or tested by science or the scientific method

  4. How Did Life Begin? • Creation Chant – the Kumulipo • Life started with kahuli, a huge movement in au (a Big Bang in time-space) • Simple plants were 1st living things • Ancient Hawaiian science is based on observation and spiritual beliefs

  5. How Did Life Begin? • Origin from non-living matter • Presence of oxygen, nitrogen, hydrogen and carbon in the atmosphere • Random events cause these atoms to combine randomly to create first stable molecules of life

  6. Charles Darwin • Father of evolution • Collected and cataloged specimen of various organisms on his travels • Came up with the theory of Natural Selection • Published his findings in a book titled The Origin of the Species

  7. Charles Darwin • Suggests that the environment shapes the organisms • Those who cannot adapt to the environment will die • Those who can adapt are able to reproduce and create more of themselves

  8. Charles Darwin • Theory wasn’t well received by public • Blasphemous

  9. Darwin’s Findings • Darwin took detailed observations of the organisms he saw • Came up with a theory that explained how they came into being • Concluded that certain organisms had traits that made them better suited to the environment • They had an advantage

  10. Darwin’s Finches • Finches found on the Galapagos islands • All looked somewhat similar • Came up with an explanation

  11. Darwin’s Finches • An ancestral finch came to the island by accident • Some offspring were capable of certain things • They had the advantage

  12. Evidence of Evolution • DNA • All organisms on the planet has DNA made the exact same way • Similar structures • Similar skeletal structures shared among many organisms

  13. Evolution in Hawai‘i • Ideal place to study Natural Selection • From one ancestral bird, a HUGE population came into being! • The Hawaiian honey creeper is a classic example of Natural Selection

  14. Related Science Careers • Bird Scientists in Hawai‘i Nei • Study avian disease (to prevent bird flu, etc.) • Many work in outreach and conservation • Many work for USGS, Hawai‘i Endangered Bird Conservation, Audubon Society, Humane Society and universities
