BIOL 1020H Lecture Notes - Lecture 6: Microevolution, Continental Drift, Convergent Evolution
Document Summary
Charles darwin & alfred r. wallace challenged the traditional view of life on earth and ushered in a new era of biology. On the origin of species focuses attention on diversity of organisms. Darwin noted that current species must be descendants of ancestral species. Evolution as defined by darwin can be understood as descent with modification. Scala naturae and classification of species (great chain of being) Aristotle viewed species as fixed and arranged them on a scala naturae from lowest to highest. The old testament holds that species were individually designed by god and therefore were perfect. Carolus linnaeus interpreted organismal adaptations as evidence that the creator had designed each species for a specific purpose. Linnaeus was the founder of taxonomy classification of organisms. Developed the binomial format for naming organisms (homo sapiens) Fossils are remains from the past found in sedimentary rock, which appears in layers or strata. Paleontology is the study of fossils: developed by georges cuvier.
