Document Summary
Herbivores consumes around 18% of terrestrial plants, and less than 50% in aquatic systems. Herbivore effects: greatest on algae, and smallest on woody plants. Parasites: a predatory organism that feeds off another but don"t kill it. Host (prey of a parasite) evolved defense against parasites. Some live with their host most of their lives. Human dna and anatomy are identical to chimpanzee, similar to puffer fish. Most body parts are also present in cows, frog . At cellular level, most raits shared with fungus, plants, etc. Charles darwin (1809-1882) wrote on the origin species on 1858: species evolve from other species. Geographic distribution: species change by favored traits (theory of natural selection) His book was controversial against the bible. By 1870"s most scientists believed in evolution. However by 1920, it people don"t believe that natural selection was main cause of evolution. Modern genetic began with gregor mendel in 1865 but was ignored until 1900.
