Ice Age Extinctions Of The Megafauna

Many of the larger animals such as mammoths and bison travel in herds, and that, along with their large size, protects them from predators. However, when the predator is Mother Nature, there is virtually no defense. For modern day elephants, drought is the biggest concern. It can take twenty percent of a herd every year, but the e...

Million Years Ago 5 Million Years
1,586 wordsHuman evolution is the biological and cultural development of humans. A human is any member of the species Homo sapiens, meaning wise man. Since at least the Upper Paleolithic era, some 40, 000 years ago, every human society has devised a creation myth to explain how humans came to be. Creation myths are based on cultural beliefs that have been adopted as a legitimate explanation by a society as to where we came from. The science of paleo anthropology, which also tries to create a narrative abou...

Therapeutic Cloning Reproductive Cloning
942 wordsIn his 1930 s futuristic novel, Brave New World, Aldous Huxley predicted a society where the human race was created in a laboratory and carried to term in incubators. At the time it was regarded as being ludicrously impossible. The idea of cloning in the eighties required multiple reproductions of specialized cells. Even then, the possibility of cloning was unachievable. Recently, scientists cloned a lamb, simply by replicating the cell in the skin tissue. It is now happening in all parts of the...

Endangered Species Atlantic Coast
1,438 words(Charadrius Melodus) Introduction The piping plover, a bird now going extinct, was once very bountiful. When an animal is going extinct, it could mean a lot of things. The Piping Plover is an endangered species. An endangered species is a name for a plant or animal that is slowly dying out. This bird is experiencing population drops, so it is called endangered.

Biotechnologist would like to receive an inch of allowance from the government to start the cloning process here in the United States. The fear, however, that cloning may become too advanced is a relevant response. Cloning is the copying of genes, or DNA, of one organism to be used in the creation of an identical one. It is similar to genetic engineering, which is the manipulation of the genes. HOW IS CLONING DONE Cloning...

Biology Of The Galapagos Giant Tortoises
1,601 wordsThe giant tortoise is probably the best known of all Galapagos animals and even gave the archipelago its name; 'Galapagos' means tortoise in Spanish and may derive from the word for saddle, referring to the distinctive saddle-like shell of some of the tortoises.

Million Years Ago Permian Extinction
1,401 wordsAnthropology Is human extinction possible? Why does this happen? What causes a species to be extinct? Can human race prevent it? To answer these questions we must first define what extinction means, what types are there and why do they occur. As extinction is a continual product of natural selection, since the dawn of competition spawned by the first meiosis event, natural selection has altered all life on earth, precariously engaging in life experiments some that work and some that dont. Those ...

The farther we take a geological question, the more other sciences come into action. If one brings up the question of geology, the first thought appears is rocks. But rocks are found to be not just stones. These rocks are stories. To figure out the Earth, rocks are where to start. If one takes a closer look at them, she or he may...

In the last five years, the science of cloning, has come to realization. What is a clone? A clone is a duplicate much like a photocopy is a duplicate, or copy, of a document (Kolate, 238). A good example of copies that occur in nature are identical twins, which are duplicates of each other. On a daily basis, molecular geneticists and other scientists use cloning techniques to r...

Millions Of Years Square Miles
1,316 wordsTigers are descended from civet-like animals called niacin that lived during the age of the dinosaurs about 60 million years ago (Dang, 1994). These small mammals, with long bodies and short flexible limbs, evolved over millions of years into several hundred different species, including cats, bears, dogs and weasels. About 37 cat species exist today (Dang, 1994). Tigers evolved in eastern Asia, but it is not exact. Sabre-tooth tigers are not the ancestors of todays tigers. In fact, sabre-tooth t...
