Evolution A look at the theory of evolution and Natural Selection How Did Life Begin? Extra terrestrial origin Life originated from other planets outside our solar system How Did Life Begin? Creation Life was put here by divine forces Cannot be explained or tested by science or the scientific method 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 How Did Life Begin? Origin from nonliving 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 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 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 Charles Darwin Theory wasn’t well received by public Blasphemous 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 Darwin’s Finches Finches found on the Galapagos islands All looked somewhat similar Came up with an explanation Darwin’s Finches An ancestral finch came to the island by accident Some offspring were capable of certain things They had the advantage DNA Evidence of Evolution All organisms on the planet has DNA made the exact same way Similar structures Similar skeletal structures shared among many organisms 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 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 Bibliography www.scihi.hawaii.edu http://en.wikipedia.org/wiki/Image:Charles_Darwin_1880.jpg, Access Date: Dec. 5, 2006 http://www.geolsoc.org.uk/photos/finches.jpg, Access Date: Dec. 5, 2006 http://hometown.aol.com/darwinpage/finches1a.gif, Access Date: Dec. 5, 2006 http://www.micro.utexas.edu/courses/levin/bio304/evolution/honeycreepers.gif, Access Date: Dec. 5, 2006 http://evolution.berkeley.edu/evolibrary/images/history/finches.gif, Access Date: Dec. 5, 2006 http://www.pa.msu.edu/people/horvatin/Images/Planets/mars/Mars.jpg, Access Date: Dec. 5, 2006 http://www.yourdictionary.com/images/ahd/jpg/A4atom.jpg, Access Date: Dec. 5, 2006 http://imagesource.allposters.com:80/images/pic/PTGPOD/515727~Sunlight-Coming-ThroughRedwoods-CA-Posters.jpg, Access Date: Dec. 5, 2006 http://www.destination360.com/europe/france/images/s/france-notre-dame-cathedral.jpg, Access Date: Dec. 5, 2006 http://www.newman.edu.hk/ecampus/wk/bioweb/ALBio/AlCh11/AlCh11Web/images/11.5.3b.jpg, Access Date: Dec. 6, 2006
