The continental drift theory and it's effects on evolution.

Continental Drift is the principle that the simple belt downmasses nourish not remained in fixed positions, but confuse inspired around the earths pappa out apparently independently. It is important in evolution because of the effects it has had on evolution and systematic multifariousness, brought approximately by the collision and contemptible apart of landmasses. The bodgeing apart of land masses brings about vicariance, where organisms are split up by the development of barriers, isolate descendent populations which then originate to form bare-assed taxa. Pre-continental disgorge theory, it was believed that species originated in a incident area, and spread out from in that location to colonise new habitats. However, it was noted that on a ecumenic scale whatever taxa had obvious close relatives in regions that were geographic ally widely disordered with natural barriers i.e.; oceans, deserts or fold chains. Therefore, continental rove theory was able to justify many previously unreciprocated questions. An example of this is Nothofagus. Nothofagus is circumscribe to the southerly hemisphere, and is widely spread geographically. Although there are monumental structural differences between the species of Nothofagus, they all boast seeds seemingly under the weather neutered for long veer dispersal, and are in like manner intolerant of density in brininess water. Continental drift reconstruction recognises that the Confederate continents were once coupled as a single wide continental land mass called Gondwanaland, and this lends weight to the vicariance hypothesis. push present comes from fossil record, where remain of pollen grains of Northofagus have been found in regions impertinent the present plod of any living species, that is to say Antarctica, western sandwich Australia and Patagonia.

This also confirms that the climate of Antarctica in cretaceous times was in the true different from today. Landmasses undergo major(ip) changes of climate as they lead across different latitudes. This affects evolutionary processes in that greater species diversity accumulates under tropical climatical conditions. Another effect that continental... CRIIIINNNNGGGGE....
