Therefore, people can gain advantage using animals. Moreover, Heffner pointed out that “[animal experimentation] benefits humans, which in turn benefits lab animals” (72). For example, the author points out a laboratory is more secure than in the wild (Heffner 75). In the wild, animals suffer to find food and shelter and so on, so the mortality rate is high. However, in the laboratories, animals do not have to worry about that because people will take care of them.
1 )artificial selection in current world? Answer : Artificial selection is the process of changing the characteristics of animals by artificial means. It was originally defined by Charles Darwin in contrast to the process of natural selection, in which the differential reproduction of organisms with certain traits is attributed to improved survival and reproductive ability in the natural habitat of the organism. For example, animal breeders are often able to change the characteristics of domestic animals by selecting for reproduction those individuals with the most desirable qualities such as speed in racehorses, milk production in cows, trail scenting in dogs. Another example is the crossing of white corn, or field corn, with yellow corn,
Cloning animals is a great idea and I think they should totally clone animal and bring back extinct animals. They need to do this and they will bring things that we need and it would be fun and it would help us.The reason it would help us is because of the way that we would use our resources. Cloning animals has been a debatable topic since 5 July 1996 the reason behind it is the first big breakthrough hit when they cloned their first major animal. This animal is known as Dolly the sheep. “It can produce a larger amount of animal population.” Cloning can both sides on how to create animals with identical genetics.
Scientists attempt to link the results of testing drugs on animals to its effectiveness on humans. There is an extreme lack of results that comes from animal testing, furthering that scientists should use methods that do not involve animals when testing new drugs and other medical
According to Biology online, Animal testing is defined as using animals in experiments and development projects usually to determine toxicity, dosing and efficacy of take a look at capsules before proceeding to human scientific trials. Animal experimentation has been functioning since ancient Greece when Aristotle and Hippocrates first made their model of the human body based on what they had observed via animal dissection. Similarly, Romans used animals to do greater medical assessments on animals like pigs, monkeys and dogs. After that, the age of the Renaissance continued medical research. “As such, the 20th century had a large boom in animal experimentation until 1980 when activists commenced standing up against the labs (Branson)”.
The use of the animals in the past, present, and future are getting worse as the time goes on. Places such as a laboratory or factory, who make the medications for humans, do not work as expected, and most labs do not even know about because of the things they do. By making all products non-animal tested it would save money, it would save many animals lives, and it would make customers rather that it was not tested. An alternative to animal testing is to use electronic devices because they are so advanced now they could simulate the same thing. All in all animal testing should not be
The main problem in animal cloning up to this time is the efficiency of the process, how effective it is for us. The recent effectiveness of Nuclear Transfer is underprivileged. The result of nuclear transfer is not really a clone because it possesses larger differences from monozygotic twins. The public has a great dissatisfaction against cloning for it is not fair to the animals and is in opposition to the law of nature. There is also a huge part of literature citing high percentage of miscarriage, stillbirth, early death, genetic abnormalities, and chronic diseases among cloned animals.
However, in human beings, the percentage may lower and may interfere with the natural biological order of life. Arguments for and against cloning of humans do not make a convincing case since reasons used to back the claims are based on various assumptions and ethical issues. The proponents of cloning argue that the technology can help in solving the problem of infertility; help in cloning dead loved ones, and solving the problem of genetic diseases. Cloning can allow a person to have a genetically copy of oneself with all positive traits. However, such claims have not been proved since no human clone has been produced so far (Melo‐Martín 246).
A 2009 study shows certain flaws in majority of the animal studies using primates. 87% of the studies were proved to be flawed as animals and humans are genetically different, results vary too. (Carol Kilkenny,2009). But to continue the process, to prove their hypothesis, scientists continue to use animals repeatedly. This causes a lot of cost.
If we want to examine whether a new medicine will work or not, the experiment should be done in the system that represents the whole human body not only just the cell. The new testing method does not provide the opportunity to study interrelated processes occurring in the central nervous system, endocrine system, and immune system. But, animal testing can provide it all. California Biomedical Research Association states that “chimpanzees share more that 99% of DNA with humans and mice share more than 98% DNA with humans, therefore, animals are susceptible to many of the same health problems as humans.” All mammals, including humans, are quite similar with the same set of organs such as heart, kidneys, and lungs which work more or less the same way. So, if we want to examine a new medicine and its effect on our body, animals are the most appropriate choice because animals and humans are so biologically similar.
Such as, elephants, chimps, monkeys, dolphins and even octopuses. The closest thing that scientists have to a circulatory system are animals, unless humans are willing to sacrifice their life for a simple scientific cause. Another way to test on besides animal testing is through computer models but according to the California Biomedical Research Association “Computer models can only be reliable if accurate information gleaned from animal research is used to build the models in the first place”. In other words they still need to test on animals (not much, but very little) to create the model they need to test on. Furthermore, the California Biomedical Research Association also stated that “Even the most powerful,
Every ten seconds, an animal will be abused. One form of animal abuse that is still debated today is animal testing. Can animal experimentation really be considered abuse? Millions of animals each year are used for biomedical research across the country. But, animal testing may not be as safe as many may have originally considered.
The polio vaccination, from the polio diseased, has reduced tremendously over the years due to animal testing. In another animal experiment, dogs pancreases were taken out which led to the finding of insulin, which brought progress to treating diabetes. Humans and animals have organs that operate in similar ways. In the case of evolution, the DNA makeup of humans is remotely similar to the DNA makeup of chimpanzees and mice. Because of this, findings in medical advancements has been made easier.
Why animal testing is necessary People would argue that animal testing is essential to find cures for illness. Animal testing has helped find, develop cures and treatments. Since in the past 100 years of testing it has resulted in many successes. Experimentation in dogs helped lead to the discovery of insulin, but the dog’s pancreas were removed as a result. Laboratory research on animals has helped researchers have a better understanding on treating illnesses such as breast cancer, brain injury, leukemia, malaria, and much more (ProCon.org).
Genetic engineering is unpredictable which could lead to negative affects in finding cures such as creating new and stronger diseases. Occupy Theory states, “Considering that genetic engineering employs viral vector that carries functional gene inside the human body; the consequences are still unknown. There are no clues as to where functional genes are being placed. They may even substitute the important genes, instead of mutated genes. Thus, this leads to another health condition or disease to human” (occupytheory.org).
