Evolution: The Origin of the Species To realize the significance of Charles Darwin’s original thoughts and ideas 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 Charles Darwin: Actions Studied and collected thousands of lifeforms 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 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 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 revolutionized modern scientific thought 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 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)
