altered the way the human race thinks about how life had come about‚ and the changes millions of species around the world have made in the past to get to where they are today. The idea of simple organisms migrating‚ dying off‚ adapting‚ thriving and changing to fit their needs of survival was unheard of‚ or solely disregarded‚ for it was not supported by many or misunderstood. That is‚ until one man‚ Charles Darwin and his evolutionary theory of natural selection was presented for the world to take into

Selina Gunsauls Hasten Anthropology 1 17 March 2017 Natural Selection Explanation A species is a group of individuals that produces fertile offspring. A population is a group of the same organisms or species. The main source of genetic variation is meiosis. Within meiosis‚ fertilization occurs and creates variation. Within meiosis‚ although it is rare‚ mutations happen which can be also a source of variation. Gene flow‚ the movement of genes within multiple populations is another source of variation

Natural selection allows for success. Naturally‚ our human instinct is to survive and become successful. How we accomplish that success is questionable. Is success granted in how far a person has gone in their career? Or is success granted in achieving high morality? Playing by the rules will not provide an individual a sense of high morality or make them more successful than those who bend the rules. Playing by the rules is synonymous with having high integrity. As a high school student‚ I am

Biodiversity J.N.M Grade 10A HIS Ms. C.W Biodiversity is the biological variety or diversity of life on Earth (Anup). It is a connection between all organisms ("10 Surprising Threats to Biodiversity"); these organisms are all part of a “biologically diverse Earth.” Biodiversity enhances productivity in an ecosystem in which all species have an important role to play. Not only does it enhance productivity but also when it is conserved and healthy‚ it offers us many different

Biodiversity: Who Cares? Biodiversity is important for many reasons. One reason it is important is for biological reasons. If biodiversity is affected in a biological community it can cause species to overpopulate or become extinct. These changes can cause issues with the goods and services that an ecosystem provides to humanity. Species’ functional characteristics influence the ecosystem properties. Every species depends on each other. If one is wiped out then another species will lose their

over inadequate preservation of biodiversity. Biodiversity is the variety of plant and animal life in the world or in a particular habitat‚ a high level of which is usually considered to be important and desirable. According to Tim Flannery‚ between 1995 and 2008‚ the number of small mammals in Kakadu National Park declined by 75% and one third of the species that were recorded in 1995 can no longer be found. I find these statistics appalling and believe that biodiversity is a big contributor to our

How the plantation affect biodiversity? The positive impacts to biodiversity of plantation Trees used in plantations may have more conservation value than existing vegetation such as pasture‚ also it may improve downstream water quality and provide habitat for aquatic biota. Moreover‚ it will sequester carbon and hence contribute to mitigating or reducing climate change. The plantation may lead to reduced pressure on the harvest of rainforests elsewhere. Most importantly‚ Biopact (2008) explained

UNIQUE AND THREATENED BIODIVERSITY The patchwork of isolated islands‚ the tropical location of the country‚ and the once extensive areas of rainforest have resulted in high species diversity in some groups of organisms and a very high level of endemism. There are five major and at least five minor centers of endemism‚ ranging in size from Luzon‚ the largest island (103‚000 km²)‚ which‚ for example‚ has at least 31 endemic species of mammals‚ to tiny Camiguin Island (265 km²) speck of land north

Rachel Newell Walter Zeller International Relations November 18‚2013 Loss of Biodiversity David Ehrenfeld says in his book Biodiversity “The value of biological diversity tells us a great deal about why biological diversity is in trouble”(212). People tend to over look the importance of biodiversity. Without it we would lose a lot of the resources that we use for important and everyday things. One example is that a lot of medicines come from plants‚ and the more plants we have on the planet
