Lamark: 1- Thought that all organisms had a natural urge to become perfect and as a result they could change their size or shape by using their bodies in new ways 2- Suggested that species are not fixed 3- Suggested that organisms could change by selectively using various parts of their bodies and could pass these acquired traits on to their offspring, enabling species to change over time (inheritance of acquired characteristics)
Darwin: 1- Variation 2- 3 distinctive patters of biodiversity: species very globally, locally, and over time 3- noticed that different yet ecologically similar species inhibited separated but ecologically similar habitats 4- noticed that some fossils of extinct animals were similar to living species
Both Darwin and Lamarck: Adaption, had no idea about DNA, believed that species are not fixed, believed species evolved, Principle of common descent (descent with modification, common ancestor), natural selection:There is natural heritable variation and there is variable fitness among individuals (survival of the fittest), survival of the fittest:reproducing and passing adaptions to the next generation
