Patterns of Evolution Humans alter our environment to suit our needs rather than adapt to our environment based on environmental stressors. Due to this fact‚ we are unlikely to be affected by the pressures of natural selection. We will not likely be affected by further evolution. In convergent evolution‚ unrelated species living in the similar environments become more and more alike in appearance as they adapt to the same kind of environment. Dolphins and sharks are examples of convergent

Questions: What are the current condition of endangered species in Canada? What are the major factors that cause species endangerment? What are the actions the Canadian government had been taken to save them? Introduction Canada is one of the biggest places on earth with extensive wilderness protected areas that are providing home for more than 70‚000 wildlife species. Among the rest‚ 488 species are categorized by COSEWIC (Committee on the Status of Endangered Wildlife in Canada) as extinct

PART 1: Question 1 Describe the differences between divergent evolution‚ convergent evolution and parallel evolution and provide an example for each type of evolution. Divergent evolution occurs when change from a common ancestral species increases as time passes‚ leading to a speciation event; that is‚ the evolution of two new species. Convergent evolution on the other hand differs from divergent evolution because it is the development of similar features separately in unrelated groups of organisms

Primary Post “The surrogate species approach is the most cost effective means for establishing national and global conservation priorities.” Conservationists are challenged with the problem of protecting a range of species at minimal costs. As such conservationists have to prioritize to help those in most need of assistance or trouble (Myers et al. 2000). Therefore‚ many conservationists have adopted the surrogate species approach as a shortcut to aid with the conservation priority decision (Caro

The Evolution of Language The study of language is very intriguing once you start looking a little farther into it. I read through many books and sources to help make the history of language a little more clear and found many interesting ideas. I found that something as simple as the way you use your hand could shape the brain‚ language‚ and human culture (The Hand). I also found many sources on human evolution; and digging a bit deeper into this area showed me many thoughts and

things come to mind such as climate change‚ water pollution‚ species loss‚ or deforestation. Yet so many other problems get overlooked because they are unrecognizable or do not get as much media coverage. One of these issues is the threat of invasive species. Some people will walk past them every day without even realizing it. After all why would anyone question something that looks just like another plant‚ insect‚ or animal. Invasive species are not as in your face as pollution or deforestation‚ but

Species Extinction - Modern Species Paper Endangered Species Act joins a couple of unmistakable environmental laws in the US. It was set apart into law by Past President Nixon‚ whose key target was to keep various endangered species from being ended using whatever strategies imperative. Since it is set to guarantee certain animals that are nearing end on our planet‚ it will make people who harm or execute them a criminal. While the law has been outstandingly viable in the rebuilding of a couple

Exotic plant invasions are causing profound changes to ecosystems around the world. However‚ it is difficult to generalise about their effects on ecosystem properties‚ since these vary according to the traits of the invading species‚ and the properties of the invaded vegetation and habitat. Yet‚ knowing the inherent functional traits of an exotic invasive plant could improve understanding of its invasion success and impact‚ since plant traits affect ecosystem properties such as through fall distribution
