1 Evolution: The Origin of the Species To realize the significance of Charles Darwin’s original thoughts and ideas

2 Charles Darwin: Facts Developed idea of Natural Selection 1831 began voyage on HMS Beagle employed as a naturalist voyage was to take 5 years with no pay

3 Charles Darwin: Actions Studied and collected thousands of life- forms during 5 year journey most famous for his observations on the Galapagos Islands studied and observed 14 different kinds of finches on the islands found one dominant type on each island; each one was different

4 Charles Darwin: The Finches 14 different versions of finches existed on Galapagos Islands Usually only 1-2 types of finch located on an island major difference between finches was beak size; shape beaks were deciding tool in success failure of birds to survive beaks were primary tool for food

5 Charles Darwin: Post G.I. Studied findings on finches and other life-forms for 20 years from his studies wrote book entitled The Origin of the Species in 1859. Was not well received; went against religious beliefs Was not well received; went against religious beliefs revolutionized modern scientific thought

6 Charles Darwin: 4 Main Points of Book All organisms produce more offspring than can survive Variations exist in all populations of species Some variations are better than others; more beneficial for survival (which we call adaptations) Overtime offspring of more successful organisms will make up the population of species

7 Charles Darwin: The Outcome Book basically states that Natural Forces are primary reasons for a species evolving; not divine powers Evolution, therefore continually is happening Variations acted upon by Natural Selection Forces (En, Dis, CF & Pred) Variations are caused by numerous factors most likely of which are mutations in an organisms DNA, that then are passed on (modern genetics) Variations are caused by numerous factors most likely of which are mutations in an organisms DNA, that then are passed on (modern genetics)
