PART 1: Lamarkism





Even though Lamarck theory was proved to be wrong, he did understand and taught us that environment had a large impact on evolution. and example of his theory would be let's say if i were to a loose a toe, that my offspring would inherit the no toe and my child would be born without a toe and that was we adapt to the environment. he beleived that new species were being created by spontaneous generation which is the belief that living things arose from non-living matter.



PART 2: Darwin's Theory


-he evaluated how different species evolved and related to one another by finding and veiwing fossils as well as assessing the land mass these species lived on.
-Galapagos Islands was home to 13 very similar species of finches. He made a conclusion that these birds had evolved from a single finch that had arrived on these islands.
-He was able to assess the location of fossils and mountains from experiencing earthquakes which moved the land mass.
-became interested in artifical selection: changing of traits in a desirale way.
-Started his study in natural selection and studying competition between species which lead to adaption to an environment therefore traits changing which causes evolution.

EXAMPLE: A finches beak changing from a small beak for eating insects and finding them in small places to a big parrotlike beak for eating fruit.
