Mass Extinction In Evolution

Mass Extinction.

Source: https://worldatlas.com

Mass extinction has impacted our earth's evolution tremendously. From as far back as 500 million years ago during the Cambrian period, to as close to us now 65 million years ago during the Cretaceous-Tertiary extinction event, and all 3 events in between have affected the animals and plants surrounding our planet gigantically. Mass extinction is when there is a rapid decrease of animals and plant species on earth due to the earth's natural disasters, some of the earth’s disasters can even lead to the evolution of a new era. For example: the Cretaceous Paleogene extinction. The Cretaceous Paleogene had a combination of volcanic activity, asteroid impact, and climate change to take 76% of dinosaur …show more content…

76% of species were lost during this era. Scientists are still questioning whether the late Devonian extinction is a single event or if it lasted for thousands of years. Trilobites which had nearly survived the Ordovician Silurian event were nearly killed during this era. What caused trilobites to nearly go extinct is: Because of all the giant plants covering the planet their roots gave nutrients to the ocean. Lands of water had algal blooms then carried on to kill animals. The volcanic ash killed spiders and scorpions on earth for this time. Another animal related to amphibian called elpistostegalians became extinct in a fast amount of time. Later on, vertebrates only appeared around 10 million years later, such as we evolved from called the ichthyostegalians. Without ichthyostegalians evolving to eventually becoming us, we would not be alive without out this …show more content…

We are living in currently in the Holocene era. As we observe the planet around us many of us noticed plants and animals are endangered at an amazingly fast rate. The result of the mass extinction is fortunately not going to be Metroid or volcanic activity. Unfortunately, the cause is most likely to be climate change due to all the humans activities currently happening, for example, all the fossil fuels we are burning like coal, oil, and gas. All these extra fumes build up in the air building up greenhouse gases, therefore the earth's surface temperature begins to rise. Causes like burning fossil fuels have triggered climate change, soon it is obvious we will have our sixth mass

Were Dinosaurs Warm Blooded

1240 Words | 5 Pages

The dinosaur extinction theory – a large asteroid impact and a giant volcanic eruption at the end of cretaceous – also supports that dinosaurs were cold blooded, when the dust due to the meteorite covered the earth, then the sun light could not penetrate the smoke and dust, thus sunlight did not enter the earth for many years, this lead to the drop in temperature on the land, as dinosaurs were cold blooded they could not raise their body temperature without sunlight and hence were

Analysis Of The Sixth Extinction By Elizabeth Kolbert

498 Words | 2 Pages

From the beginning of The Sixth Extinction by Elizabeth Kolbert we can see a very different style of writing from what we previously encountered in Encounters with the Archdruid. The Story is told in a more colorful and up beat way. As we begin the book the author talks about humans and their destructive nature on the planet. I really enjoyed how Kolbert depicted as if she was telling the history of any other creatures. When she describes how man is pollution of the planet she did in a way that to me painted the picture of an animal that was destructive in nature, as If the best thing for earth and all of its inhabitants would be the removal of this plague.

How Does Lee Use Social Inequality In To Kill A Mockingbird

610 Words | 3 Pages

People are More than a Color People in the world today are often found not to get along, because of different backgrounds of ethnicity. Many people will say they dislike someone because of their personality just to hide that on the inside they really disapprove of their color. Those who conform to such idiotic thoughts based on race are the people that prevent this country from progressing due to their unwillingness to critically think wholeheartedly about significant racial issues, but choose to rely on past false perceptions without understanding the complexities of racial issues.. The story To Kill a Mockingbird by Harper Lee conveys how social inequality, good and evil, and moral education contribute to racial stereotypes.

Why Is The Brush Tail Possums Considered Microevolution?

713 Words | 3 Pages

Environmental change plays an important role in evolution. When an environmental change occurs, it can be a physical or chemical change. It can also be a gradual process such as the formation of mountains, or it can be a rapid and unexpected change, such as a natural disaster. When changes in organism’s environments occur, they must adapt to their new environment, this can cause ample amounts of selective stress and pressure on organisms, causing some species to eventually die out, while other organisms strive and evolve to be better adapted to this change.

Ancient Mass Extinction Of Earth's Creatures Summary

1132 Words | 5 Pages

Sallan and Andrew Galimberti, the co-author of the study, looked at the fossil records of over one-thousand species of vertebrates that were alive during the ninety-six million year period before and after the mass extinction. For sixty million years the size of the vertebrates steadily increased in size reaching up to sizes matching a school bus. However, the vertebrate species that survived the mass extinction during the thirty-six million year period following the mass extinction were much smaller compared to the size of the vertebrates before the extinction. In fact, most of the surviving species observed by the team were measured to be less than forty centimeters in length. Information about this adaptation was published earlier in The Science Magazine, which stated that this change is unrelated to the climate and oxygen levels at the time.

Dbq Essay On Population Growth

Population growth has continued to grow and people have continued to use up the earth’s resources. Climate change is an issue caused by humans and their disregard for the planet. Humans have used up so much of the earth’s resources that it poses a threat to all things living. Animals are becoming extinct and their habitats are being lost. Humans need to expand and build more places to live because there is not enough space for everyone due to population growth.

Summary: The Most Widely Accepted Extinction Theory

182 Words | 1 Pages

The most widely- accepted extinction theory is that a meteorite hit Earth and caused the dinosaurs to go extinct (“First Dinosaur Encyclopedia” 114,115). Without evidence of a crater, the theory couldn’t have been established (“Thomas Sumner: What Killed the…”). Luckily, Geologists discovered remains of a huge crater in Mexico during the 1990s (“First Dinosaur Encyclopedia” 114,115). In fact, there was another way scientists could prove their theory about the extinction was correct. It involves the K-T boundary.

Arguments Against Gene Manipulation

523 Words | 3 Pages

The guest speaker at the Bovay Lecture this year was Ronald Sandler, and he covered the topic of genetic manipulation in order to save various species of animals. Entire species are disappearing at an alarming rate: up to several thousand per year, which is several orders of magnitude larger than historical trends. Species all across the globe have become more susceptible to extinction, particularly those that must live in very specific habitats such as the Artic, freshwater lakes, deserts, and islands to name a few. Most of the extinctions today result from non-local causes, such as the global climate change. By contrast, in the past a significant portion of species extinction could be attributed to local causes, such as a community clearing a forest to make farmland.

Despite animals bring a superior capability to adjust what happens over plants do, they might also die. When the animals and plants die, the public loses two sources of food, plant nourishment and animal nourishment. They might additionally lose their homes.

The Importance Of Saving The World

The extinction rate is one hundred to a thousand times greater than it was before the human species evolved on the planet. Currently, Earth is in its sixth mass extinction, with one sixth of all species going extinct. If all of these species go extinct, humans will also be greatly harmed (Worrall). Humans can not continue without the great interconnected biodiversity we currently have, because all animals on the planet are inter-connected in their habits and way of life. If we begin to destroy minor food chains from small-scale animals going extinct, greater and greater
