For centuries‚ two possibilities have been the subject of much debate. Either the beginning of the universe just happened by coincidence‚ or an intelligent being is responsible for its creation. Scientists agree that in order for the universe to be coincidental‚ it would have to be infinite in age. During the

The Origin of Theatre By Sheldon Fairfoot “It is unlikely that anyone will ever know just how theatre emerged” (Grose & Kenworthy‚ 1985: 3). Though there is little certain evidence‚ strong indications‚ scattered throughout our history‚ point to theatre finding its origins in the ancient rituals of shamanism.

Archaeology 103 12/10/12 The Origins of Agriculture As the last Ice Age came to an end‚ the environment presented its self in a new manner. The temperature was becoming warmer‚ promoting more plant life‚ resulting in a better quality of life. Many scholars argue why farming was invented. Palaeopathological studies‚ or studies of diseases in ancient man and fossil animals‚ have shown that in populations where cereal farming was practiced the health had diminished. Also because of intensive cereal

Out of all the species that have ever existed since the beginning of time‚ 98% of them are extinct (Facts). There are an estimated 5-10 million species that exist currently and only 1.5 million have been identified (Sherry‚ 2). Scientists classify species into six different groups: plants‚ animals‚ insects‚ algae‚ fungi‚ and microorganisms (Today’s Situation). In the tropical rainforest alone‚ most species are disappearing at the rate of 1% a year (Sherry‚ 6). If the current trend continues‚ at least

PROTECTION OF NATIVE SPECIES There are numerous ways that non-native or exotic species can have a negative impact on our environment and the diversity of life on our planet. The statistics are very alarming and more attention should be paid to the problem and finding a solution to the problem before the cost is more than we can bear. When compared with other threats to Biodiversity‚ the introduction of exotic species ranks second with habit destruction ranking first for being the cause of extinction

Invasive Species The invasion of non-native species is one of the United Nation’s top five environmental concerns; however the term invasive species is one which many people do not fully understand. It is a term used in the media‚ by governments and ecologists‚ to indicate to the public that a new species has entered an area‚ and usually very little is said afterwards‚ however many people do not realise the severity and long term effects of invasive species in their area and worldwide.

LOSES OF BIODIVERSITY Some species that are more vulnerable to extinction than others include species at the top of food chains‚ such as large carnivores. Endemic local species which is a species found in only one geographical area with a very limited distribution‚ species with chronically small populations‚ migratory species‚ species with exceptionally complex life cycles and specialist species with very narrow requirements are also the examples species that are more vulnerable to extinction

Hydrilla: An Invasive Species Hydrilla verticillata‚ otherwise known as Hydrilla is an aggressive water weed and is said to be one of the world’s worst invasive aquatic plants. Hydrilla in temperate places around the globe and somehow made its way to the United States. Hydrilla has a special advantage; it grows under lower light conditions than nearly any other species‚ it only needs about 1% of sunlight. This advantage allows hydrilla to grow underneath other plants and survive greater depths;

Delgrosso 1 Biology and Society 12/02/13 In the present day there exists two species of elephants. These two species have many relatives that have come before them and died out. Several of these species are Paleomastodon‚ Deinotherium‚ Gompotherium‚ Primelephas which is a direct ancestor to the modern day elephant‚ Stegadon‚ American mastodon‚ and wooly mammoth. All of these species are considered Proboscidea which are mammals that have trunks “proboscidea encompasses the trunked mammals”

the late century‚ extinction becomes common topic in our daily discussion and debates. An average of 27‚000 species is currently extinct each year and there is a possibility of 22% of extinction in the overall species if action is not taken. Animal extinction is due to human immorality and irresponsible behavior just for their own benefits. Since the year 1600‚ a total of 83 mammals species are known to have become extinct. Wildlife population depleted the trade in live animals‚ damaged habitats
