Alexandra Vallarino Ricardo Acosta ENGL 101 16 November 2010 Promoting Conservation of Fauna and Flora Let’s take a look at our country. Panama is the tiny piece of land that joins North and South America. Our position in the globe gives us a climate and a type of land that holds a rich biodiversity of tropical species of both fauna and flora. Nowadays‚ ‘Panama is turning into a little Miami’‚ some people would say. There are many projects to build up the city; and in the recent years‚ the government
Premium Biodiversity Species
Australia’s unique flora and fauna Australia has over 1 million different native species. Australia’s unique variety of plants and wildlife has evolved as a result of our countries unique conditions. This is a result of Australia’s geographical isolation. From deserts to rainforests‚ mountains and plains; this environment has created unique animals suited to their environments. As a result: * Australia has 10% of the world’s biodiversity. * Out of 20‚000 species of vascular plants 4 in 5

Continental Drift is the principle that the continent landmasses have not remained in fixed positions‚ but have moved around the earth’s surface apparently independently. It is important in evolution because of the effects it has had on evolution and taxonomic diversity‚ brought about by the collision and moving apart of landmasses. The drifting apart of land masses brings about vicariance‚ where organisms are split up by the development of barriers‚ isolating descendent populations which then evolve

Continental drift has helped create the diversity we see present in modern day plants and animals. Through a process of speciation‚ the movement of the continents has had a generous role throughout evolution‚ effecting and distributing flora and fauna. The Earth’s continents were once one‚ a large supercontinent called Pangea that later separated into two smaller ones known as Gondwana and Laurasia. The separation and collision of continents has not only created some of the valleys and mountain ranges

University May 15‚ 2012 Alfred Wegener first proposed the theory of “continental drift” in 1915 after finding evidence on continents that had drifted apart‚ matched very closely when the continents were brought together. Wegener also stated that the fossils found in a particular place often indicated of a possibility that the climate from the region is totally different from today. All of his facts supported the theory of continental drift. Wegener first suggested that the continents fit together like
Premium Plate tectonics
who did much of the early work on continental drift? In the early 20th century‚ German scientist Alfred Wegener published a book explaining his theory that the continental landmasses‚ far from being immovable‚ were drifting across the Earth. What evidence did this scientist have to support his idea of continental drift? Wegener noticed that the continents seemed to fit together‚ not at the continuously changing shoreline‚ but at the edge to their continental shelves. He derived this hypothesis

Continental Drift and Plate Tectonics Theory (Part 1a) Introduction: The Beginning of the “Continental Drift Theory” In the middle of the eighteenth century‚ James Hutton proposed a theory‚ uniformitarianism; “the present is the key to the past”. It held that processes such as geologic forces- gradual and catastrophic-occurring in the present were the same that operated in the past. (Matt Rosenberg‚ 2004) This theory coincides with the theory of Continental Drift that was first proposed by Abraham

Theory of Continental Drift The seven continents used to be one giant continent named Pangea. They spread apart and became what the continents are today. The shapes of the continents line up‚ the fossils line up with how the continents‚ the rock formations on both sides of the Atlantic line up with the fossils and coastlines‚ and climatic evidence proves the Theory of Continental Drift. The first piece of evidence for Continental Drift is the shapes of the continents. All of the continents fit

Why is the flora and fauna of Australia so unique? Evolution is ultimately an unpredictable process. Although it can be predicted in the short term through knowledge of natural selection and inheritance‚ long term evolution is randomly altered by the interaction of highly variable factors. Such factors include the randomness of genetic diversity within a species and the process of natural selection acting upon this. Also significantly altering evolution is the unpredictable movement of tectonic plates

The environment is currently in a state of gravely precarious instability pushed to this edge by careless human activity. The impacts within the atmosphere are evident – temperature changes‚ increased storm activity‚ and melting
