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

production of GMOs‚ because of the fact that the genetically modified organisms can interact with the environment and cause the transfer of harmful genes which can lead to the elimination and extinction of all natural organisms. It may not be a well known fact but GMOs have greatly increased our quality of life. GMOs have mainly helped our agricultural industries by increasing the size and the quality

Extinction of Dinosaurs Ryan Humphries Biology 6th Period Two-hundred and thirty million years ago the first dinosaur-like creature roamed the earth. Within five million years it could be considered a dinosaur. They were soon at the top of the food chain. They populated every continent. Then 65 million years ago they vanished. The most powerful creatures ever to live on earth had become extinct. Dinosaurs were not the only victims of this "mass extinction." There were many other species

reasons as well as argument for necessity of conducting such campaign. First of all‚ the environmental degradation is widely recognized as a primary reason. In fact‚ the deforestation and environment pollution have put creatures on the verge of extinction. Domestic apes in Vietnam‚ which have die out due to shrinking of tropical trees‚ could be taken as a particularly salient example of this. Ignoring the impact of human on minimizing the habitat of animals is thereby a grave mistake. Additionally

pterosaurs‚ ammonites‚ and many families of brachiopods and sea sponges. Also‚ many shark species as well as most vegetation did not survive(“Dinosaur Extinction”). What could have possibly killed off the dominant animal group of the time? The answer to this question is still unclear but there are many hypotheses that attempt to explain this extinction event. To find out exactly how this happened‚ evidence must be gathered not only from fossils

Ever since the history of Earth has been studied using fossil records‚ extinctions have always been the object of fascination and interest‚ particularly the mass extinctions that occurred throughout Earth’s history. A mass extinction can be caused by disruptive global environmental changes‚ where large numbers of species have become extinct (Urry

Extinction is the end of an organism or group of taxa. Extinctions occur when a species becomes unfit for survival in its natural habitat usually to be replaced by another‚ better-suited species. An organism becomes ill-suited for survival because its environment is changed or because its relationship to other organisms is altered as stated from Credo Reference. The moment of extinction is generally considered to be the death of the last individual of that particular species. Mass extinctions‚ however

to some natural reasons or human’s insatiable hunger for money‚ particularly the endangered species of animals that require more attention to prevent them from being extinct in the near future. One of the major factors that are leading to the extinction of animals is deforestation. Mass deforestation by human has cost a lot to the habitat of animals. The animals are being forced to move away from their natural habitat as it is being destroyed by human. Major source of food for animals came from
