Mass extinctions

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

megafaunal mass extinction took place. It’s still debated whether humans are to blame for this, since this megafaunal extinction happened after the arrival of humans or if climate change is entirely to blame. Fossil evidence has been of great help in finding what factors might’ve caused this extinction. This mass extinction that took place is related to the Anthropocene because if humans were the main cause, humans need to be more careful now because their actions may lead to more extinctions. The observations

The sixth mass extinction is the only one caused by another species. There are 200+ species a day dying off. Human’s waste of trash and littering is destroying ecosystems all over the globe. The sixth mass extinction is creeping up on humanity, and we can prevent it but we are turning a blind eye to this catastrophe. The sixth mass extinction is was caused by humans in various ways such as poaching. Poaching is huge in Europe and Africa, they hunt for tigers, then they use various parts of the tiger

The Cretaceous mass extinction is the most well-known case of meteorite impact on the earth, but it certainly is not the only one. It is merely the most well-known. Due to the impact, debris entered earth's atmosphere and caused the plant life of the time to die off due to the lack of sunlight to survive. This made food much more scarce for the species that were dominant at the time. The competition was simply too much for them, and as the plant life died out, so did the herbivores and then the carnivores

The mass extinction of the Dinosaurs has been a subject of interest and dispute for many scientists over the years. There are many different theories on what happened to them: did some planetary destruction happen, did they die out, were they wiped out, or was it the cause of something not of this planet. This question and this need to solve the mysteries of the world has continued to draw scientists in for the never-ending search for the answer. Scientists have worked tirelessly in an attempt

possibly agree or disagree with this theory. Yes, I do think that the extinction had to deal with some kind of mass cloud coming over ruining the living conditions, but this theory is too over the place for me to say that I completely agree with it. I believe that the ideas about how the fog cloud could have covered the entire earth, but if it were to do that I feel like it would have created a mass extinction. Not just a dinosaur extinction. Going back to evolution, if dinosaurs had such a strong adaptation

The sixth mass extinction is on the way and could be as massive as the extinction that wiped out the dinosaurs (Kolbert, 2014). Before learning more about the sixth mass extinction, you’ll have to first understand what biodiversity is and what will happen when you tamper with it. According to Anup Shah, author of Why is Biodiversity Important? Who Cares, biodiversity means the variety of life on Earth or in an ecosystem. Every species plays an important role in the ecosystem or in the world, no matter

We are currently in the midst of our sixth mass extinction. A bold statement, yes, but a true one nevertheless. There have been five previous mass extinctions, each having been triggered by an cataclysmic event, resulting in at least seventy-five percent of species going extinct. Though, this time around, the blame is being pointed elsewhere. Towards us. Are humans responsibly for the sixth mass extinction? Many seem to think so, including Harvard Biologist, E. O. Wilson, who has estimated around

The Cretaceous mass extinction had two theories on how and why it happened through the impact hypothesis. The first one was suggested that an asteroid collided with Earth 65 million years ago. Luis Alvarez and his son, Walter Alvarez found “high levels of the rare metal iridium” in the layers of the Earth during the periods of the Cretaceous and Tertiary located in Italy. Their proof is that it was the cause of extinction by an asteroid the size of 10 kilometers. The second impact hypothesis was

There are, however, several plausible causes for each extinction event that either by themselves, or with the help of other factors, triggered the mass extinctions of a numerous amount of life forms. One of the largest supposed causes of many mass extinctions are flood basalt events, which are the result of a giant volcanic eruption, or series of eruptions, that coat large stretches of land and the ocean
