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 Developed idea of Natural Selection 1831 began voyage on HMS Beagle 1831 began voyage on HMS Beagle employed as a naturalist employed as a naturalist Was the 3 rd Choice for the job Was the 3 rd Choice for the job voyage was to take 5 years with no pay voyage was to take 5 years with no pay

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

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

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

Charles Darwin: 4 Main Points of Book All organisms produce more offspring than can survive All organisms produce more offspring than can survive Variations exist in all populations of species Variations exist in all populations of species Some variations are better than others; more beneficial for survival Some variations are better than others; more beneficial for survival Overtime offspring of more successful organisms will make up the population of species 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 Book basically states that Natural Forces are primary reasons for a species evolving; not divine powers Evolution, therefore continually is happening Evolution, therefore continually is happening Variations acted upon by Natural Selection Forces (En, Dis, CF & Pred) 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)
