THE CONCEPT OF SPECIES What are species? Species are the basic taxonomic units of biological classification. This grouping of organisms of "like kind" into discrete and stable units has been traced at least from the time of Plato and Aristotle. The term derives from the Latin "specere" (to look at‚ to behold)‚ with the meaning of "kind‚“ "quality‚" "appearance‚" "shape‚" or "a peculiar sort.“ In the past‚ species were classified according to their shape. Carl Linnaeus (1707-1778)‚ the

Amphibians are becoming a vanishing species. There are a number of causes for them dieing. But the most recent and worst cause has been discovered. It is responsible for killing off our amphibians. They are dieing by the thousands. They were able to survive and hold on through past extinction spasms‚ surviving even when 95 percent of other animals died out. They even stayed alive when the dinosaurs disappeared. If amphibians could live longer than dinosaurs‚ then why are

On the Origin of Species chapter IV outlines Darwin’s proposal on how a new species is generated via natural selection over a long period of time. In Darwin’s theory of speciation‚ he proposes that all organisms within a species must express some degree of variation‚ which allow for organisms with the most advantageous variations to produce the most offspring (Darwin 10) This also means that the variations must be heritable from one generation to the next. In chapter IV Darwin uses the examples variants

I have chosen the Eridanus constellation. I chose this constellation because I did a project on this constellation in muggle school a few years back. Eridanus is a river constellation. It is in the southern hemisphere. It is Greek for the Po river located in Italy. This is questionable because in ancient times‚ Eridanus was thought to be the Nile river‚ since it was so special. It’s the 6th largest constellation we can see from Earth. The main star of this constellation is Archernar‚ also known as

Endangered Species Report The endangered animal I picked was the Ailuropoda melanoleuca. The common name is the Giant Panda. They are playful‚ poor breeders‚ and they are becoming extinct because of many things. The giant panda is a earthy animal and primarily spends its life roaming forests and eating bamboo. They climb trees and they also use trees or openings in rock for shelter. Giant pandas do not have permanent dens though. Because they do not have permanent dens

Based on the provided case study‚ “Stakeholder Management and the Endangered Wildlife Trust”‚ written by Gavin Price‚ I will address the following three questions: 1.

He also writes about the “problem of purpose” idea and how evolution and natural selection solve
