Species

Evolution is an issue that has been highly debated ever since the eighteen hundreds when the theory of evolution was proposed by Jean-Baptiste Lamarck and then elaborated upon by Charles Darwin in his book Darwin on the Origin of Species. Darwin used a variety of research to elaborate on the theory of Evolution and to provide evidence for the theory. Although some disagree, the theory is true, and there are many types of evidence to support the theory such as Fossils, Similar embryos, and…

The Endangered Species Act has been in law for about four decades and people gave mixed opinions about this. The Act included the right to take away land to persevere for animals use and that an animal cannot be excitant anymore. Palm Spring, California about thirty-one thousand acres of Agua Caliente Band of Cahuilla Indians were taken away to save the big horn sheep. The Tribe sued the government claiming,”An economic impact of hundreds of millions of dollars”. The Tribe was paining to make a…

Species And Why it Matters If They Become Extinct According to the famous definition by Ernst Mayr, a species is said to be “a group of interbreeding natural populations that are reproductively isolated from other such groups (Ridley)”. This quotation defines the biological species concept that is a largely accepted definition of a species. The human population is increasingly becoming a reckless civilization with no regard for the actions we follow therefore the concept of a species becoming…

An invasive species is an organism that is not native and has negative effects on an economy, environment and health of an individual. Moreover, an invasive species can be a plant, animal or other organisms that might create negative impacts to the society. Furthermore, the definition can further be enumerated as a species that is non-native to the ecosystem under consideration and whose introduction creates results that are inefficient to those surrounding it. The impacts that are often created…

a. (EARTH) does have a case to challenge the FWS and NMFS decision not to list the shad. The Endangered Species Act (ESA) was made to stop species that are on the road to extinction, and put them on the path of recovery. The big mouthed shad is one of those species, which relies on Maine rivers for its lifecycle. The FWS and NMFS have completed a status review and have decided, against contrary data, that the fish should not be listed. Much like the spotted owl case (NORTHERN SPOTTED OWL v.…

and Native Species Did you know that there are at least 212 non-native species in San Francisco alone. Many of you might not know what a non-native species is. Well, a non-native species is a a type of organism living outside its native distribution area which has been due to human activity, while a native species are organisms that normally live and thrive in a particular habitat or community. But there is one other type, a non-native invasive species. A non-native invasive species is a…

As an islanded nation Australia was comparatively free of invasive species that existed in other countries, until post-Colonial times increasing trade between Australia and foreign countries has caused an increase in the species entering the country. Invasive species are a threat to the environmental, social and economic health of Australia. Invasive feral animals such as pigs, goats, rabbits, cattle, buffalos, donkeys, camels and Horses cause degradation to natural habitats by selective or…

“On the Origin of Species” (fully titled “On the Origin of Species by Means of Natural selection, or the Preservation of Favored Races in the Struggle for Life”), was published by Charles Darwin in 1859. This book is modern foundation of evolutionary biology. Although the idea of evolution had been discussed widely prior to Darwin, there wasn’t a widely accepted mechanism by which evolution could occur. This mechanism is known as natural selection or the survival of the fittest. Interestingly…

In the paper, “Origin of Species”, author Ray Comfort presents opinions and non-supported assumptions to discredit the contributes of Charles Darwin to science literary. Charles Darwin’s contributions to science by his data, theories, and arguments for evolution by natural selection are exceptionally important in how scientist classify and explain evolution acting in nature. From variation in phenotype to the passing of favorable traits, to succeeding generations, to how life itself became,…

You would think deer species are pretty spectacular from the way they have adapted to the environment. Have you noticed their hind legs? They’re built for running and jumping. It allows the deer to make sharp turns, speed up between 37-50 miles per hour and not to mention, jump over 12 feet! They camouflage to the environment from season to season by shedding their fur coat. Deer can sense a predator from a great distance with their prominent cup-like ears, and eyes that are located on the sides…
