PDF-[EBOOK]-Evolution: What the Fossils Say and Why It Matters

Donald R Protheros Evolution is an entertaining and rigorous history of the transitional forms and series found in the fossil record Its engaging narrative of scientific discovery and wellgrounded analysis has led to the books widespread adoption in courses that teach the nature and value of fossil evidence for evolution Evolution tackles systematics and cladistics rock dating neoDarwinism and macroevolution It includes extensive coverage of the primordial soup invertebrate transitions the development of the backbone the reign of the dinosaurs and the transformation from early hominid to modern human The book also details the many alleged missing links in the fossil record including some of the most recent discoveries that flesh out the fossil timeline and the evolutionary processIn this second edition Prothero describes new transitional fossils from various periods vividly depicting such bizarre creatures as the Odontochelys or the turtle on the half shell fossil snakes with legs and the Frogamander a new example of amphibian transition Protheros discussion of intelligent design arguments includes more historical examples and careful examination of the experiments and observations that are exploited by creationists seeking to undermine sound science education With new perspectives Prothero reframes creationism as a case study in denialism and pseudoscience rather than a field with its own intellectual dynamism The first edition was hailed as an exemplary exploration of the fossil evidence for evolution and this second edition will be welcome in the libraries of scholars teachers and general readers who stand up for sound science in this posttruth era. Cornell Notes pg. 137. What is a Fossil?. Preserved remains or traces of plants, animals, and other organisms.. Types of Fossils:. mold fossils.  (an impression made in the rock- like a footprint in sand). Remains . of once living organisms.. Form from decay and are buried by sediment.. Sediment hardens into rock and preserves the shape of the organisms.. Fossils. Fossils . Remains. Molds. . Casts. . “Evidence for Evolution”. We will look at major evidence supporting theories of evolution:. Fossil Record . Comparative Anatomy . Biogeography . Biochemistry. Evidence Supporting Theories of Evolution . Organism DNA. 1a. Some of the strongest evidence for evolutionary relationships comes from studying the DNA of different organisms.. 1b. The fact that all organisms use the same DNA molecule to code for genetic information suggests that these organisms share a distant ancestor.. Fossils can tell us about our biological (life) past…. We’d have to build stronger refrigerators.. FOSSILS can tell us about our. B. IOLOGICAL PAST.. How can fossils help tell us Earth’s . GEOLOGIC. Evolution. Evolution. Evolution as an Idea…. Aristotle . Living things are . “Immutable”. Buffon (1707-1788). Observed anatomical features that seemed to serve no purpose and wondered why they existed.. Molds and Casts. Carbon Films. Preserved Remains. Trace Fossils. Petrified Fossils - . How do they form?. Mineral rich water soaks into cracks and crevices. Minerals “precipitate” and fill the spaces.

The theory of evolution by natural selection was proven by the following methods: . Fossil . Record. Biogeography. Anatomy. Embryology. DNA. Fossils are found within the layers of sedimentary rock. . 1. Blood . proteins in horses are chemically similar to blood proteins in monkeys.

Fossils have helped determine approximately when life first appeared, when plants and animals arrived on land, and when organisms became extinct.. CONDITIONS NEEDED FOR FOSSIL FORMATION. Whether or not a dead organism becomes a fossil depends upon how well it is protected from scavengers and agents of physical destruction, such as waves and currents.. Geologic Time and Evolution Earth Has a History Geologic materials record enormous changes. Earth is a complex, evolving system. Physical and biological systems continuously interact. Earth constantly changes and has done so through time. Fossils, Geologic Time, Absolute & Relative Dating, and Natural Resources Chapters 5 & 6 How Do Fossils Form? Fossils are found in sedimentary rocks like sandstone, limestone, and shale In Virginia, most fossils are
