What is known as the Endangered Species Act began in mid-1960. In order for the Fish and Wildlife Service to expand their efforts to protect endangered species‚ Congress enacted the Endangered Species Preservation Act of 1966. This Act did little more than allow a list of endangered species to be made. The Act did not prohibit the killing of endangered species or the destruction of their habitat. The lack of legal protection for the endangered species led the Fish and Wildlife Service

and assign each organism a universally accepted name. They do this by using a Dichotomous Key to classify organisms‚ the binary nomenclature‚ DNA‚ and RNA. In the taxonomic nomenclature naming system‚ there are different levels called a taxon (taxa plural) or taxonomic category. The different levels to the taxonomic nomenclature naming system are called: Domain‚ Kingdom‚ Phylum‚ Class‚ Order‚ Family‚ Genus‚ and Species. The first scientist to use the system was Carolus Linnaeus. His system

Millions of species inhabit Earth. How do scientists make sense of them all? First‚ scientists study the similarities and differences between organisms. The scientists study characteristics including obvious physical traits‚ such as hair or leaves‚ and molecular traits‚ such as DNA sequences. Then‚ scientists use the information to classify species into meaningful groups. The groups may also reveal which species are related and how they fit along the evolutionary tree. Scientists who specialize in

This report is based on the study of ‘Species Diversity and Ecosystem Stability’ of the New Amsterdam Secondary School’s Eastern Field. This study was carried out by yours truly‚ Cynthia Rutherford‚ from the 26th January‚ 2011 to 5th February‚ 2011. Even though the study was done over a short period of time‚ I do hope that it will be lots of benefit to you the readers and edify you of our environment. Thank you.

Although On the Origin of Species sparked many wondrous and compelling new thinking in science‚ it also caused unintentional ideas and debates. Some of these ideas were social and some were religious. Although Darwin knew his findings would cause some disruption and new ideas‚ he never planned for his findings to reignite one of the most world-renowned debates: the debate between religion and science. Darwin pronounced‚ "I see no good reason why the views given in this volume should shock the religious

Extinct Species: Dodo Bird Joseph Sulaiman Pd.2 The dodo (Raphus cucullatus) was a flightless bird endemic to the Indian Ocean island of Mauritius. Related to pigeons and doves‚ it stood about a meter (3.3 feet) tall‚ weighing about 20 kilograms (44 lb)‚ living on fruit‚ and nesting on the ground. The dodo has been extinct since the mid-to-late 17th century. It is commonly used as the archetype of an extinct species because its extinction occurred during recorded human history and was directly attributable

time. The evolution of our earth‚ and it species has been a very debated topic over time. There is a lot of evidence that supports evolution and you have found a lot of great evidence that proved this theory to be true. The proposal that species variation locally‚ globally and over time was your idea‚ and is agreed with widely today. Natural selection is one of your other theories that is known all over the world today. Both natural selection and species variation have helped develop the theory

Invasive species are living organisms that cause harm to a environment they are not native to. Invasive species are extremely important because they tend to cost society and nature a lot of damage.For example‚ invasive species can have an effect on half the species that are endangered in their native land .They can also contaminate the soil which can lead to the alteration of hydrology in streams‚ wetlands‚ lakes and rivers. The Black Rat (ship rat) is one of the worst known invasive species. They have

The Female of the Species is written by Joanna Murray-Smith‚ and directed by Kate Cherry. The plot is inspired by an incident in 200 when feminist author Germaine Greer was held captive in her own home by a mentally unstable student. The play manipulates dramatic elements‚ particularly tension‚ symbols‚ and mood to create dramatic meaning. ”Tension is the force which drives a drama. It is said to be the most important element‚ and no drama exists without some form of tension.” (Haseman et al‚
