Document Summary
Late devonian period (1) led to 83% of marine species lost (2) happened because of global cooling and loss of oxygen in the ocean: 3. Darwin finches: he observed many different species of finches on various islands, speculated they could have descended from a single pair of mainland finch and as they expanded they acquired. 14 different features based on the environment: interactions shape the organisms, darwin and origin of species, 1836: returned to england, 1838: read work by rev. Dar(cid:449)i(cid:374)(cid:859)s (cid:449)ork: 1859: on origin of species by means of natural selection, darwin gets all the credit, wallace might have pushed him to publish his work after so long, dar(cid:449)i(cid:374)(cid:859)s e(cid:454)pla(cid:374)ator(cid:455) model of e(cid:448)olutio(cid:374) (cid:271)(cid:455) natural. Selection: uses a flow chart observation, observation 1: organisms have great potential fertility, which permits exponential growth of. Important take away: random process due to mutation being run by nonrandom things like natural selection, variation is random (causes bc of , mutation, sexual reproduction.
