Should we be able to clone extinct animals? The question isn’t can we, it’s should we. No, we shouldn’t. The questions we should consider are “Where were their habitats,” “What caused their extinction,” “When did they become extinct?” Chances are, many of you don’t know the answer to most, if not all, of these questions. So, “Where did these extinct animals live?” According to the article “Should We Be Trying to Bring Extinct Species Back to Life” even if a species was brought back from extinction, it wouldn’t have a place to live.There is a significant chance that the habitat the animal lived in is long gone and maybe even the cause of the extinction in the first place. Animals can be cloned, but what about their habitats? It is nearly impossible …show more content…
So if there is no form of nourishment, what are the animals going to eat? This would be a hindrance to the food chain. Not only that, but cloning animals is not a sufficient use of our time. The article, “First Extinct-Animal Clone Created” states that an extinct animal, a Pyrenean ibex, a subspecies of the Spanish ibex, had been brought back to life using cloning for the first time and died minutes after birth. This just goes to show that using technology can result in so many different errors and will just result in a waste of time and money. Now, while we can’t say the exact price of cloning animals as the price depends on many different factors, the price is anywhere around tens of millions of dollars just to clone a few toads according to the article, “The Cost of Resurrecting Extinct Species Could be Devastating.” If these animals that are being cloned are going to die within days of their birth, they aren’t really being resurrected. Their just being put out in the world to once again become
Beginning with the creation of the world, hunting has been over thousands of years for a number of reasons. Nowadays, hunting is considered one of the most interesting outdoor activities that have many advantages. However, hunting is a very controversial topic, for some might consider it very harmful and dangerous for the environment. Although this point of view is adopted by a part of the society, one can counter it with a numerous reasons. Hunting provides several benefits for those who partake in it and for the environment as well.
Humans have driven many animals extinct, but should we bring them back is the question. Geneticists, biologists, conservationists and ethicists gathered to discuss the controversies. Some people say in doing this we are playing God, while others say we did by killing them. Other scientist say that it may be beneficial because it will add biodiversity, and medicinal properties back to the ecosystem. It is only possible to bring species back from around 10 thousand years ago. Recently scientists have vastly improved the cloning process. We can now coax adult animal cells into any type of cell, including eggs and sperm, then manipulating them into full-fledged embryos, which has led to the ideas and developments of reviving many other species including mammoths, frogs and
The background of this article gives information that is necessary to understand the experiment. The shape of the pelvic girdle is an appropriate predictor of both phylogeny and movement in terrestrial vertebrates. However, in marine vertebrates, the gravitational forces typically applied to terrestrial pelvic girdles are not there and therefore have little impact on the shape of the girdle. Pelvic girdles of fish are generally not attached to the vertebrae and primarily are used as a place for muscles to attach and supporting of the fins. The authors discuss how in many cases the pelvic girdle could be removed and not result in any complications. However, there are some marine vertebrates that are capable of bottom walking on the ocean floor with their fins. In batoids, the pelvic fins are used for walking, which is when pelvic fins move in an alternating fashion, or punting, when both pelvic fins move at the same time. There is also augmented punting; this is when the vertebrate uses both the pectoral fins and the pelvic fins to generate more thrust, this action decreases the forces on the pelvic fins during a punt. While this locomotion would
Sarai Michel English 9HP, Period 4 When I was six years old, my parents took me to SeaWorld for the first time. I remember clearly watching the Shamu show and sitting in the splash zone, ending up soaked in water by the end. But I also distinctly remember wondering how an animal so big and beautiful could ever be happy in such a small tank, so far away from home. The animals could never possibly experience the joy they would have out in the wild where they belonged.
Today, we as a society world wide have a new issue to deal with. Science has discovered the means in which to clone animals, opening a whole new discussion. Many people are inclined to say why would science even wish to peruse this method of research. Lewis Thomas says in his essay "The Hazards of Science"
Christopher McCandless’ long, fascinating, but ultimately fatal journey into the wilderness of Alaska is depicted in the biography, Into the Wild, written by Jon Krakauer. Late in the of summer of 1990, a very young Christopher McCandless left his ordinary world in Annandale, Virginia to pursue a solitary life in the untamed wilds of Alaska. Many will insinuate that Christopher McCandless’ actions were childish and idiotic, but a stronger argument would be that his unconventional thinking and desire to live life on his own terms allowed him to reach self-actualization.
Cloning has been in nature for thousands of years, a clone is a living thing made from another consisting of the same DNA. For example identical twins are clones because they have the same DNA but the differ because the twins begin after conception when a zygote, a totipotent stem cell, divides into two, some plants self-pollinate and produce a seed, which in turn, makes plants with the same genetic code (Hyde). According to the Human Genome Project there are three types of cloning, DNA, therapeutic and reproductive; DNA cloning involves transferring DNA from a donor to another organism, therapeutic cloning, known as embryo cloning, involves harvesting stem cells from human embryos to grow new organs for transplant, and last is reproductive cloning which creates a copy of the host (Conger). One of the earliest cloned animals was a sea urchin by Hans Dreisch in the late 1800’s. Unlike Victor Frankenstein, Dreisch’s goal was to prove that genetic material is not lost in cell division, not to create another being, (History of Cloning) stated by Frankenstein “that I might infuse a spark of being into the lifeless thing that lay at my feet.” There are many ways an animal...
But on the contrary, many scientists believe that cloning can be such a positive achievement, not only for medical purposes, but for fighting extinction. For example, what if they could clone many of the endangered species that exist today? There are very few hundred of many beautiful animals that if something isn’t done to save them, they will be extinct in a few years. So if scientists could successfully clone and create these endangered species, although it would still depend on the clone maturing correctly and being able to reproduce successfully, it could be a great
Cloning has become a major issue in our modern world, from moral, ethical, and religious concerns, to the problem of financial and government support. Human cloning is one of the most controversial topics, and because of this, many of the new important discoveries and beneficial technologies have been overlooked and ignored. Reproductive cloning technology may offer many new possibilities, including hope for endangered species, resources for human organ transplants, and answers to questions concerning cancer, inherited diseases, and aging. The research that led up to the ability to clone mammals started more than a century ago. From frogs to mice to sheep to humans, reproductive cloning promises many possibilities.
Modern-day genetic technology has granted mankind with the opportunity to bring back extinct species from the dead. If humans have come to possess the DNA from an extinct animal population, it is possible to create an identical clone of the animal in question, effectively “bringing it back from the dead”. Many ethical dilemmas surround the practice of de-extinction, and rightfully so. Recreating an extinct species could produce groundbreaking scientific breakthroughs, generating exciting opportunities for future genetics-based research. However, there could also be monumental consequences: the newly revived, once-extinct species might destroy the ecological equilibrium of modern Earth

First of all, “Australia’s first cloned sheep appeared to be healthy and energetic the day she died, during the autopsy they could not find the cause (Castro, 2005).” There are many risks to cloning and you are seldom able to identify the cause of their death. “More than 90% of cloning attempts fail (Human Genome Program, 2006).” Most cloned animals died mysteriously even before they were born or when they were very young, so there is hardly any information on how clones age. Clones may be born with a normal looking body but may have internal functioning problems. “Cloned animals tend to have more compromised immune function and higher rates of infection, tumor growth, and other disorders (Human Genome Program, 2006).” There are many risks of cloning and a major factor is genetic differences.
Taken from the only place you've ever known. Away from the only family you have. Kept in crates and cages to be sold. Removed from their home, exotic animals are put in yours for personal amusement.This act is ruinous an inhumane, it violates the basic rights of human and animals. Exotic animals have a rightful place in their natural habitats, not as pets, because they endanger the community, become sick, and their owners abandon them.
Cloning should be banned, because animal cloning is unsafe, and this won’t make a cloned act the same. “Cloning the animal would never replicate the exact pet due to the many environmental factors that influence personality and even appearance.” (Issue). A cloned animal has never gone through the same things that the original animal has. This will cause the clone to look different in some ways and act differently.
Australian researches have made major steps towards bringing frog that was extinct in 1983 back to life. Although the procedure of de-extinction is much more complex than cloning living animals. A group of scientists (Lazarus Project team) believe humans have the skill and obligation to repair the damage they have done to the world, which has caused numerous species to die out.
