Many Species of the Mammoth - 1479 Words
There were many different species of the Mammoth. Examples include Mammuthus meridonalis (Southern Mammoth), Mammuthus primigenius (Woolly Mammoth), etc. (Brooks, 2008). Mammoths are best described as bigger, modern-day elephants covered in a thick coat of fur and are symbolic of the ice age. This is due to their large size, their vast population of the North and South Pole, and their ability to adapt to extremely cold temperatures (Douglas, 2013). Some ways these mammals managed to survive in their environments were that their coats consisted of long, dark guard hairs and fine under wool allowing them to stay warm; the thick insulating layer of fat that was found underneath their coats and that their cheek teeth were large and made up of compressed enamel plates that were great for grinding up the tough dry grasses that they fed on. It is estimated that the earliest an elephant-like animal lived was 58 million years ago. Mammoths first lived in Europe and Asia about 2.5 million ye ars ago and entered North America about 1.7 to 1.2 million years ago (Brooks, 2008). The last living Mammoth is approximated to be as recent as 3700 years ago. However, due to the rapidly changing environment and the increased human predation of these species, there was a significant drop off in the population of Mammoths 11,000 years ago (Douglas, 2013). Research on some of the social aspects of Mammoths showed that they often travelled in herds, where the adult Mammoths were very protective ofShow MoreRelatedThe Majestic Mammal631 Words à |à 3 Pagesto six years for a Woolly Mammoth Calf to wean from a mother (as cited in ââ¬Å"Columbian Mammoth Channel Island Mammothâ⬠). Mammoths were interesting creatures. They roamed the earth for thousands of years. They even survived one of the greatest ice ages in Earthââ¬â¢s history. There were many different kinds of mammoths that evolved, and eventually, went extinct. When one studies the genus of mammuthus, they might w ant to look at interesting facts, the different species, how they evolved with theirRead MoreWORK INTRODUCTION Theoretically, mammoths could be cloned by recovering, reconstructing or900 Words à |à 4 Pages WORK INTRODUCTION Theoretically, mammoths could be cloned by recovering, reconstructing or synthesizing viable mammoth DNA and injecting it into the egg cell of a modern elephant whose nuclear DNA has been removed; alternatively, mammoth genetic material could be introduced into an elephant genome in order to create a mammoth-elephant hybrid or chimera. The possibility of bringing extinct animals back to life has fascinated people for years. While something like Jurassic Park is unlikely, PleistoceneRead MoreThe Evolution Of Primates859 Words à |à 4 Pagesrelations were observed in Minoh, Osakaââ¬âa city in central Japan. As uncommony documented as interspecies relations can be, they are a known phenomenon, and itââ¬â¢s been observed as early as the Holocene epoch or even the Pliocene epoch by way of the extinct mammoth. Scientists at Lethbridge are referring to this as a behavioral trend, something that isnââ¬â¢t expected to last. There were lots of monkey-deer interactions reported in January 2017 on Yakushima Island, and other locals in Minoh have been said toRead MoreCharles Darwin s Theory Of Evolution And Natural Selection1535 Words à |à 7 Pageshis book On the Origin of Species, the method of being naturally selected for a better chance of survival in an environment. Evolution itself is the process by which organisms develop and adapt over generations. ââ¬Å"â⬠¦ it follows that any being, if it vary however slightly in any manner profitable to itself, under the complex and sometimes varying conditions of life, will have a better chance of surviving, and thus, be naturally selected.â⬠ââ¬â (Darwin, 1859) Darwin observed many pieces of evidence thatRead MoreThe Importance Of Chromosomes897 Words à |à 4 Pagesincompatibility between mouse oocyte and mammoth nucleus. Then again let us assume that we find an intact nucleus having a proper DNA inside it, there are still many obstacles to overcome. One being lack of enough knowledge and information about the number of chromosomes that mammoths possessed. Moreover, Y chromosome in a mammal is typically very small and repetitive, therefore, making it hard to sort it out. But, the solution can be sequencing only the female species. Also, determining the exact sequenceRead MoreCharles Darwin s Theory Of Inheritance Of Acquired Characteristics1197 Words à |à 5 Pagesvery debatable topic since the theory of evolution first evolved. By definition, evolution is ââ¬Å"the process by which different kinds of living organism are believed to have developed from earlier forms during the history of the earthâ⬠, but there are many different types of ââ¬Å"evolutionâ⬠such as coevolution, divergent, parallel and convergent ââ¬â all with different theories.

It is the moderation of characteristics that can alter an entire population over a long period of time and is the theory that explains the variation in each generation of an organism. Charles Darwinââ¬â¢s theory was natural selection, the survival of the fittest and the struggle for existence, which had a great impact on selective breeding. Organisms that were well-adaptedRead MoreThe Pleistocene epoch was a time period of almost 2 million years of repeating glaciation around700 Words à |à 3 PagesAlthough this was a time of mass extinction for species that could not adapt to the climate changes, many mammals and vertebrates that can be identified today were found during this time (Zimmermann, 2013). The Pleistocene epoch is an important foundation for understanding life that exists today, including carnivores, herbivores as well as the evolution of humans. Fossil preservation has always been the most accurate way to determine what species lived during a specific time period. Through correlationsRead MoreDid humans cause the mass extinction of megafauna during the Late Pleistocene period?1601 Words à |à 7 Pagesmammal extinctions occurred around the time of Clovis occupation, yet only two, the mammoth and the mastodon, have ever been associated with human sustenance, and even those only appear at 14 of 76 early Palaeoindian sites (Hyne 391, Waguespack 70). Granted, Martin attributed the limited kill site record to the swiftness of the extinction, but if this were a realistic explanation, why would there be 12 examples of mammoth kill sites, 2 mastodon kill sites, and 0 kill sites from the 31 remaining extinct
