There are many animals that are going extinct now than ever before. Dolly, the first successful clone of a sheep [mammal], was perfectly normal. She was a mother of six lambs, which were all bred the old-fashioned way.
A life-size model of a mammoth at the Royal BC Museum; some people would like to bring mammoths back to life Source A Fascinating Idea Bringing extinct animals back to life is a tantalizing idea for many people.
Although there are problems still to be solved, the process is gradually becoming more feasible. Whereas a few years ago scientists thought that recreating extinct species was an impossible task, some are now saying that it may be within the realm of possibility in the not-too-distant future, at least for some species.
In fact, some Japanese scientists predict that they will be able to clone a woolly mammoth within five years. How could resurrecting an extinct species that has long disappeared from the earth even be possible? The key is finding the DNA, or deoxyribonucleic acid, of the species.
DNA is the molecule that contains the genetic code of an organism. The embryo that develops from the egg is then placed in a surrogate mother to develop. The chemical is located in the nucleus of our cells. The chemical is also present in animals, plants, bacteria, and some viruses.
A lot of research is being done in relation to DNA and its activity, since this molecule is the key to life. The research is helping scientists understand how life works.
A gene is a segment of DNA that codes for a particular characteristic of an organism.
However, scientists are finding fragments of deoxyribonucleic acid in some ancient animals. These animals died in environments that partially preserved their bodies, such as very cold climates. A Columbian mammoth skeleton at the George C. The sperm inserts its nucleus into the egg. Once the egg nucleus and the sperm nucleus have combined during fertilization, the egg divides and produces an embryo.
Cloning is a process in which identical organisms are produced by a non-sexual process. In cloning, the researchers place all of the DNA needed to make the desired organism in an egg, so no sperm is required. The egg is triggered to divide artificially in order to make an embryo.
Somatic cell nuclear transfer is a common cloning method.Should we bring extinct species back from the dead? Why bring back extinct animals? A second option is cloning. Scientists would . cloning extinct animals Essays: Over , cloning extinct animals Essays, cloning extinct animals Term Papers, cloning extinct animals Research Paper, Book Reports.
ESSAYS, term and research papers available for UNLIMITED access. List of Cons of Cloning Extinct Animals. 1. Animal Exploitation It comes as no surprise that one of the greatest concerns of re-introducing an extinct species back into the modern world is that of animal cruelty, abuse and exploitation.
Why Revive Extinct Species? The Case for Reviving Extinct Species by Stewart Brand National Geographic News (Published March 11, ) Thanks to new developments in genetic technology, DNA may eventually bring extinct animals back to benjaminpohle.com species whose DNA is too old to be recovered, such as dinosaurs, are the ones to consider .
From an ecological perspective, cloning endangered and extinct animals is not practical. Cloning endangered species may lead to apathy regarding the issues of why species are becoming endangered in the first place (Salsberg, ). Aug 29, · Bringing back extinct animals and cloning are exciting ideas.
It will be interesting to see how the technology and the debates about its appropriateness progress! AUTHOR. Linda Crampton. 5 years ago from British Columbia, Canada.
Hi, Pamela. Yes, that is a worry about cloning. We may have laws about what can be done in our Reviews:
