extinction is the end of an organism or of a group of organisms (taxon)‚ normally a species. Ordovician-Silurian extinction‚ global extinction event occurring during the Hirnantian Age (445.6 million to 443.7 million years ago) of the Ordovician Period and the subsequent Rhuddanian Age (443.7 million to 439 million years ago) of the Silurian Period that eliminated an estimated 85 percent of all Ordovician species. This extinction interval ranks second in severity to the one that occurred at the

Extinction Extinction is the termination of evolutionary lineage. The most common extinction event is the loss of a species. There are many reasons why a species might die out. Human intervention (either directly or indirectly) has become the leading cause of species extinction (possibly for the last fifteen thousand years). Species and Populations An important distinction must be made between true extinction and extirpation. Extirpation is the loss of a population‚ or loss of a species

BIOL2110- Vertebrate Zoology Word count: 1056 Dinosaur extinction: An analysis of events and theories that possibly led to the dinosaurs’ demise. 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

The exact reason for the Pleistocene extinction is still not known‚ this data implies that top-down forces and humans are the reason the extinction happened. This data is important because during the Anthropocene humans continue to put animals at risk for another extinction. The authors used data from the Pleistocene and recent data to show that high rates of predation and humans could have lead to the extinction. Both carnivores and humans caused the extinction‚ because both were competing for prey

Over fishing is a serious problem that the world faces today. With sea food consumption at an all time high and the oceans resources being fished almost to extinction. We have to look towards the future of maintaining our oceans resources. "Only 10 percent of all large fish-both open ocean species including tuna‚ swordfish‚ marlin and the large ground fish such as cod‚ halibut‚ skates and flounder-are left in the sea"(National Geographic‚ pg. 1) To help maintain and preserve our oceans resources

ones to get called to receive an organ. For a lot of those people‚ they die waiting on that list. If more people would become donors‚ there would be a lot more organs available for the ones in need. There have been many ideas on how to solve this problem. Rather it being an organ donor to receive an organ‚ some sort of point system‚ or financial incentives. (Calne‚ 2010) Offering financial incentives to potential organ donors‚ would solve the organ donation shortage in America. Organ transplantation
