Woolly Mammoth Research Paper

Faith & Surovell offer hopes for further testing for biological and spatial histories of individual species and their migrations in relation to climate, ecology, and human permeation. They state this will uncover which if not all of the three main mechanisms: climate change, overkill, and extraterrestrial impact, caused the North American mammal extinctions in the late Pleistocene (Faith and Surovell, 2009).

In the The Case for De-Extinction: Why We Should Bring Back the Woolly Mammoth the author talks about how to bring these extinct animals back by using DNA and how it will not only benefit us but the upcoming generations. Unlike the author in the The Case Against De-Extinction: It’s a Fascinating but Dumb Idea he says “as National Geographic photographer Joel Sartore has emphasized to me, zoos are already overwhelmed trying to breed endangered species for reintroduction and thus facing triage conundrums about which species to save and which to let go.” (Ehrlich n.pag.) So as I stated in the claim if we can`t bring back the extinct animals we should at least protect the ones that are about to go extinct and learn from our

“Opponents of bringing back extinct species think that it may make people less concerned about future environmental destruction” People would not half to worry about environment distractions if they bring back the Wooly Mammoth because it would make its environment healthy again. “De-extinction could offer insights into evolution and natural resources that are currently unavailable to us.” Even humans could get something out of bringing back the Wooly Mammoth such as resources that we don’t have right now that could help us in the

Did the Mammoth and Mastodon come from a distant or common ancestor? I will be explaining whether the Mastodon and Mammoth came from distant or common ancestors. Also, I will be explaining why they migrated to North America. I will be trying to explain this by using DNA evidence to determine if they came from distant or common ancestors.

These factors were: 1) food scarcity, ultimately the result of a changing climate and 2) increased human contact and hunting. This deadly combination led to their disappearance. The mammoth population was already low by time that they were hunted by humans some experts argue that even if every human on the planet at the time killed a mammoth once every three years, the woolly mammoth would have become extinct (National Geographic). So, while climate change dealt the mammoth a crippling blow, it may have been human hunters who landed the killer blow in sealing their fate as an extinct

This lead to many different tests being performed throughout the years to conclusively discover how several particular classes of mammoths actually evolved and what drove the changes within. The arguments of mammoth evolution discussed in this paper are not completely factual, for there is not enough evidence behind studies to confirm these tests and experiments as completely factual; rather everything that will be discussed will be based on scientific theory. Due to this, do not

FROM THIS REASONING our "out-of-Tibet hypothesis" was born. The Pleistocene was the heyday of so-called megafauna, mammals weighing 100 pounds or more, many larger than their modern relatives They included the woolly rhinos, giant sloths, and saber-toothed cats, all now extinct. We envision ancestral megafauna using high-altitude Tibet, with its cold habitat and thin air, as a "training ground" where they evolved anatomies and behaviors that later served them well in an Ice Age climate farther north. A burning question is whether, besides the woolly rhinos, Tibet could have also been a cradle for other such

The most recognised school of thought was that climate change, occurring rapidly during the end of the most recent ice age, caused alterations in the environment that the Mammoths were unable to adapt to. We can look at various types of proxy evidence to support how climate change led to Mammoth’s extinction. Firstly, by looking at frozen carcasses of Siberian Mammoths we are able, in some cases, to investigate what its diet used to consist of. For example, when the intestines were still preserved in a frozen carcass, it was possible to identify its last meal, telling us about the vegetation in the mammal’s surroundings before it died. This helps us in the understanding of how the species became extinct, as mammoths were herbivores, feeding on grasslands, and changes in climatic conditions caused changes in vegetation or loss of habitat.

The more recent of these ice ages, encompassing the Marinoan & Varangian glacial maxima (about 560 to 650 million years ago), has been proposed as a snowball Earth event with continuous sea ice reaching nearly to the equator. This is significantly more severe than the ice age during the Phanerozoic. Because this ice age terminated only slightly before the rapid diversification of life during the Cambrian explosion, it has been proposed that this ice age (or at least its end) created conditions favorable to evolution. The earlier Sturtian glacial maxima (~730 million years) may also have been a snowball Earth event though this is unproven. The changes that lead to the initiation of snowball Earth events are not well known, but it has been argued that they necessarily lead to their own end. The widespread sea ice prevents the deposition of fresh carbonates in ocean sediment. Since such carbonates are part of the natural process for recycling carbon dioxide, short-circuiting this process allows carbon dioxide to accumulate in the atmosphere. This increases the greenhouse effect and eventually leads to higher temperatures and the retreat of sea

Not long ago, recently actually, a by-chance discovery was made in permafrost. First mistaken for a deer carcass, half submerged, was the small and fragile body of a 10,000 year old baby woolly rhino. It was estimated that it was about 18 months when it passed away, and then spent the next 9,998 years (and some change) frozen in the Sakha Republic.

‘’Did humankind prevent the start of an ice age during the Holocene? Discuss arguments for and against the Early Anthropogenic Hypothesis.’’ The Holocene Epoch is the timescale given to the last 11,700 years of earth’s history, beginning at the end of the last ice age. (BD Smith et al, 2013)

Additionally, the author suggests other elements that may be involved in extinction of dinosaurs. For example, the climate might had become worse. Consequently, the food shortage appeared, on which the dinosaurs relied. Or, sea and oceans had dried that made adverse situation for dinosaurs existence.

Throughout the long history of the Earth, the global climate has fluctuated drastically, ranging from tropical to glacial. In the mid-18th century, the Industrial Revolution began, and humanity began a bilateral campaign: one waged with the goal of achieving a prosperous, industrialized future, and another, inadvertently waged against the environment. The purpose of this literature review is to examine the influence of anthropological global warming on the overall climate and to investigate the impact of humanity compared to natural circumstances. Although there is a small, but vocal dissenting minority, an overwhelming majority of researchers agree that

In the last 100 years, Earth’s average temperature has risen by 1.4°F. The rising global temperatures have caused changes in weather and climate. Global warming refers to the ongoing rise in the average temperature near Earth’s surface. This is causing a climate change, which refers to any significant change (major change in temperature, precipitation, or wind patterns) in the measures of climate lasting for an extended period of time (several decades or longer). Due to this, it is projected that the temperature will rise from 2 to 11.5°F in the next hundred years (US EPA, 2014). The “drivers,” which are the principal causes making this occur, are very controversial. It is debated whether a change in temperature is due to the work of

Rapid climate change also ends up on the suspect list of possible dinosaur extinction events. During the latter part of the Cretaceous Period continents broke up causing volcanoes to erupt and fill the sky with gas and ash resulting in a drastic climate change (“Dinosaurs Climate Change and Biodiversity”). The shifting of continents changed the Earth’s landscape, altering weather patterns and overall climate (“Dinosaur Extinction Theories”). Also, over a long period of time, climate gradually changed. Ocean habits changed, temperatures grew much more extreme causing scorching summers and frigid winters (Norell, Dingus, and Gaffney). Radical temperature changes like these led to a green-house effect, making life for the dinosaurs a lot
