Continental drift theory and s effects evolution

Introduction Evolution itself is simply the process of change over time.

When it comes to mass extinction continental drift is the mega-killer, claims Australian palaeontologist Dr Malte Ebach. Dr Ebach will explain area cladistics, its applications and some surprising results at a media conference at 12 noon at the Melbourne Museum.

Their remains are found worldwide. Dr Ebach measured thirty different features on the heads of individual trilobites from what is now Africa, North American, South American, China, Europe and eastern Australia. He fed the data, along with the location where each trilobite was found, into a specially designed computer program.

Dr Ebach and Prof Humphries reported in the April edition of Journal of Biogeography that trilobites living in what is now the southern and central United States were much closer to eastern Australian trilobites than those from Africa or South America.

Dr Ebach says the technique will enable scientists to investigate the movement of continents, the surface area of coastlines and the biodiversity of ancient life. The results promise to be immensely important. He is one of sixteen young scientists presenting their discoveries to the media, public and students for the first time, at Fresh of the recurring attacks on evolution comes from those who find the notion of random change distasteful.

One of the more pernicious and persistent claims is Fred Hoyle's oft-quoted comment that accepting that evolution occurs by selection is like thinking that a would result if a hurricane went through a junkyard [Hoyle ]. The evolution of four, subaerially nourished, sandy beaches is described in detail.

The Evolutionary Theory of Aging and Life History Theory Early history[ edit ] Abraham Ortelius Ortelius[4] Theodor Christoph Lilienthal[5] Alexander von Humboldt and[5] Antonio Snider-Pellegrini Snider-Pellegriniand others had noted earlier that the shapes of continents on opposite sides of the Atlantic Ocean most notably, Africa and South America seem to fit together. In his Manual of GeologyDana wrote, "The continents and oceans had their general outline or form defined in earliest time.

• The sand subaerial center of mass moves alongshore in the direction of the seasonally reversing, wave radiation stress Sxy. Continental Drift was a revolutionary scientific theory developed in the years by Alfred Wegener (), a German meteorologist, climatologist, and geophysicist, that put forth the hypothesis that the continents had all originally been a part of one enormous landmass or supercontinent.

Theory of Continental Drift The continental drift hypothesis was developed in the early part of the 20th century, mostly by Alfred Wegener. Wegener said that continents move around on Earth’s surface and that they were once joined together as a single supercontinent.

Evolution: Evolution, theory in biology postulating that the various types of plants, animals, and other living things on Earth have their origin in other preexisting types and that the distinguishable differences are due to modifications in successive generations. It is one of the keystones of modern biological theory.

To a large extent, the early work in plate tectonics was provoked by startling new geophysical observations coming out of. the U.S.
