Climatic evolution in australia

Tweet Australia is an island continent with a distinctive and unique flora unlike that found on any other land mass. The evolution of its plants was a result of Australia's long isolation from the other continents. The story starts in the cretaceous period Ma when the flora of the world began localising, particularly in the southern continents Australia, Antarctica, India, South America and Africa due to the splitting of Gondwana.

Gaining Access to Diverse Foods The first known stone tools date to around 2.

Making and using stone tools also conferred versatility in how hominin toolmakers interacted with and adjusted to their surroundings. Simple toolmaking by stone-on-stone fracturing of rock conferred a selective advantage in that these hominin toolmakers possessed sharp flakes for cutting and hammerstones that were useful in pounding and crushing foods.

Basic stone tools thus greatly enhanced the functions of teeth in a way that allowed access to an enormous variety of foods. These foods included meat from large animals, which was sliced from carcasses using sharp edges of flakes. Bones were broken open using stones to access the marrow inside.

Other tools could be used to grind plants or to sharpen sticks to dig for tubers.

Tool use would have made it easier for hominins to obtain food from a variety of different sources. Tool use would have widened the diet of hominins. Meat, in particular, is a food that was obtainable in equivalent ways, with similar nutritional value, in virtually any type of habitat that early humans encountered.

Although making simple toolmaking may have developed originally in one type of environment, the carrying of stone tools over considerable distances — and becoming reliant on stone technology — may have arisen due to the benefits of altering the diet as environments changed. The oldest known stone technology — called Oldowan toolmaking — involved carrying rock over several kilometers and is found associated with a variety of ancient habitats.

Redistributing stone and other resources, such as parts of animal carcasses, by transporting them may have helped hominins cope with variable habitats. The Expanding World of Early Homo As predicted by the variability selection hypothesis, hominins were not found solely in one kind of habitat, but rather in a variety.

The Pliocene climatic and environmental evolution of southeastern Australia: evidence from the marine and terrestrial realm Author links open overlay panel S.J Gallagher a D.R Greenwood b D Taylor a A.J Smith a M.W Wallace a G.R Holdgate a. The climatic evolution of the Indian and Australian continents from the Late Permian to Jurassic is simulated using a version of the National Center for Atmospheric Research Community Climate Model (CCM). The purpose is to evaluate the effects of changing model boundary conditions on climate for the time of the supercontinent Pangea. The climatic record is deduced from palaeobotany and some other relevant studies. The record from southeastern Australia is the most comprehensive and is presented for comparison with other parts.

A major signal of the ability to tolerate different environments was the dispersal of the genus early Homo beyond Africa into Asian environments. Early evidence of the diversity of Homo erectus environments in Asia includes the following sites: Dmanisi, Republic of Georgia, 1.

This site has grasslands surrounded by mountains with forests. Hominins had access to lava as a raw material for tools. This site, located near an ancient lake, had a mixture of habitats with grasslands, bushlands and forests.

Nihewan Basin, China, 1. The Nihewan sites were also near a lake. Hominin toolmakers experienced many changes in vegetation over time, with habitats ranging from forests to grasslands.The Pliocene climatic and environmental evolution of southeastern Australia: evidence from the marine and terrestrial realm Author links open overlay panel S.J Gallagher a D.R Greenwood b D Taylor a A.J Smith a M.W Wallace a G.R Holdgate a.
