In biology and ecology‚ extinction is the end of an organism or of a group of organisms (taxon)‚ normally a species. The moment of extinction is generally considered to be the death of the last individual of the species‚ although the capacity to breed and recover may have been lost before this point. Because a species’ potential range may be very large‚ determining this moment is difficult‚ and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa‚ where a species

Plants Extinctions causes and effects on human Nowadays ‚ animal extinction is a broad issue‚ one that involves the habitats and environments where other species live and interact with one another . Only a minority of people are concerned with extinction in today痴 society‚ while others might argue that it is a small problem because we are beyond the point of evolution and thus don’t really need to rely on other animals at all. According to statistics of scientific research‚extinction is

Ever forget the existence of human animals and the environment so that most of us have succumbed to the demands of modernization and progress. Humans have killed the flora and fauna around us to make way for development. Implications

Extinction is the ceasing of a species to exist on this Earth. A species officially becomes extinct when all of the species no longer exists. A species is to become certainly extinct when there is an extremely small number of it and it is unable to reproduce to create more of itself. Therefore‚ we say a species is in for certain extinction if it cannot reproduce itself. Extinctions occur at a great pace and species that we did not even know existed become extinct all the time. Scientists say that

Over the past 200 years‚ humans have made significant changes to natural environments all over the globe‚ and most of these changes have negatively affected wildlife‚ forcing unprecedented numbers of species toward extinction. However‚ extinction is a natural biological process that has been a part of species’ evolution since the beginning of time. Fossil records have shown that‚ even before humans were a part of the world’s biota‚ natural factors such as overspecialization ‚ competition‚ sudden

Brink of Extinction In Malaysia today the survival of wildlife have taken second place to human activity. All major wildlife species are now threatened with extinction. Does saving these endangered species and taking necessary actions for those who are on the brink of extinction means anything to you? Most of us are not aware that our Malayan Tiger‚ Clouded Leopard (Roy Goh 2011)‚ Pygmy Elephant‚ Sumatran Rhino‚ Orang-Utan and Turtles are in the under-extinction animals category

numbers of endangered species are still increase rapidly. However‚ there were still numbers of selfish people that did not even concern about the animal species that disappeared. Animal extinction can be defined as animal species no longer stay in the earth as it already disappeared. The factors that lead to animal extinction are irresponsible human’s hands that destroyed animal’s habitat by deforestation‚ illegal wildlife trades and climate change. Deforestation is the main causes that lead animal species

De-Extinction is one of the hottest topics in the science world currently and it tops the lists of conservation and genetic scientists alike for next big project. Though this could be a great way to learn of past species and finally see them for ourselves‚ at what cost is a species revived? The idea of bringing back an extinct species‚ such as some type of dinosaur‚ comes with many questions that most find to be debatable. Conflicts arise from every aspect of this “new” animal including how it is

Extinction and Evolution Ecology helps us understand the importance of mass extinction in evolution‚ and it also helps us understand some of the causes of extinction. Ecological niche is one of the most important concepts to understand. An animal or plant lives in a certain place is active at a particular times‚ and eats certain things; all these factors describe its ecological niche. Our environment is parted into millions of ecological niches‚ each that represents a probable home for life
