Permian–Triassic extinction event

most to see resurrected. Astonishingly, scientists have actually finagled a way to potentially make this poll useful. Biological scientists have discovered a method to conceivably resurrect extinct animals from their evolutionary graves. Termed de-extinction or species revival, this concept has evoked a substantial amount of social, ethical, and legal friction. Although the…

to Extinction Dinosaurs have captured the whole world’s attention and curiosity. How did they come to be extinct? What factors led to this downfall? Are they completely extinct? All these questions additional to several others have aroused among many scientists. Although the extinction of the dinosaurs was the smallest one it seems to be the most discussed (Meyer, 2016, personal communication). So what was the cause of the end of these grand creatures? In the article “The ‘Great Extinction’…

The excerpt Crash Course (Nancy Honovich) describes what asteroids are and everything about them to how often they occur and how close they have to be to be too close for comfort. At the beginning of the story, it tells about what asteroids are and their history. They even said that a comet called the Shoemaker-Levy 9 sped towards Jupiter at sixty kilometers a second. That is really fast! It also told about how sixty-five million years ago, it is thought that one measly asteroid could have…

(2001), and Barnosky et al. (2011) talked about the impact of mass extinction on the biological history of earth. Benton (1995) talked about how mass extinction drives diversification in the biological community, Erwin (2001) discussed on how species recovery occurs after mass extinction and Barnosky et al. (2011) talked about the possibility of future mass extinction based on the comparison between the present and past extinction data. According to Benton (1995), the massive…

To begin with, 65 million years ago was the start of the Paleocene epoch that was the establishment of the tertiary period on earth. Due to the extinction of the dinosaurs during the previous period, there was a heap amount of mammals accumulating and evolving from their original size and aspects. Many forms of animals existed big, small, and of many different sizes; rapidly increasing in numbers by reproduction. In this epoch, carnivores were very large in numbers. For example, a bird that was…

The K-T or the Cretaceous-Tertiary extinction, was a mass extinction over unknown origin that took out an estimated 60-75 percent of all the species on earth 66 million years ago, most famously the dinosaurs. It was the end of the Cretaceous period and the Mesozoic Era and created the beginning of the Cenozoic Era that is still happening today. Geologically speaking this extinction happened in a very short amount of time. Although the most well known species to go extincted during this time was…

AMERICANA SO IMPORTANT? Before I give the importance to these amazing creatures I would like you to know first what this creatures are. These creatures have existed for more than 300 million years. Meaning they have survived at least one massive extinction event and numerous catastrophes. Scientists have identified approximately 4,500 species of these creatures and 30 are classified as pests. And guess where Periplaneta Americana is identified? These creatures are hard to kill and they are…

For 16 years, scientists wondered just what had happened with corals in the Florida Keys. In this time period, over half of the corals had perished. They later discovered that the greatest decline was in elkhorn coral. Finally, research showed that the massive coral disappearances were caused by a disease by the name of white pox. The scientists have solved the elkhorn coral mystery using the scientific method - by making observations, conducting experiments, and drawing conclusions. Initially,…

history there have been five Mass Extinctions, a global event where at least 75% of the life on Earth dies. In most of these events the only life form to survive are bacteria, or other small organisms that can hide from the destructive force that wipes out everything else. The Cretaceous-Tertiary (K/T) is the most recent and most famous Mass Extinction, taking place 65 million years ago. The K/T is the event in which the dinosaurs died in. The cause of this event is debated, however it is widely…

THEIR ARE MANY MANY THEORIES ON WHY THE DINOSAURS BECAME EXTINCT THE CAUSE OF THIS MASS EXTINCTION VARIES WIDELY. Some of those theories are that Years ago an asteroid crashed onto Earth’s surface. Mountains formed within minutes. In America, a tsunami hit covering plants and animals, under piles of rubble. Debrie was scattered, The planet was broken down and it stayed that way for years. But the most clear explanation to why the dinosaurs rapidly died out with the Mose scientific evedence is…
