UNIT 1: Introducing BiologyWhen Knowledge and Ethics Collide
Scientists can change an organism’s genes. Should they?
Our ability to change living things grows as we learn more about life. But sometimes biotechnology makes us question whether we should change organisms just because we can. Maybe the technology is dangerous or maybe it challenges our values. Consider the greenish pig in the photo. A gene from a fluorescent jellyfish was added to its genome by genetic engineering. Genetic engineering holds great promise for medicine. But how and when should we alter an organism’s genes?
What is Bioethics?
A short answer is that bioethics is the study of the moral questions that are raised as a result of biology research and its applications. But what do questions of ethics have to do with biology? It might seem better to leave questions about values in a philosophy or social studies class. However, today’s cutting-edge research often prompts discussions about some of our most basic values. In the end, you might find that biology class is the best place to consider any number of ethical questions.
Ethical questions require all of us to make decisions about "the right thing to do." Often, the right thing to do is very clear. The decision benefits ourselves, our families, and our society, and it follows the accepted values of society. However, many times a decision about an ethical issue is not so obvious. It is in these cases when strong feelings on different sides of an ethical question can produce conflicts—in ourselves, our families, and our society. Can we rely upon biology, or any other scientific field, for our decisions?
For better or for worse, science can only provide us with information. The knowledge that comes from scientific research is very useful, and often necessary, in helping people arrive at decisions, but science only provides part of the answer to ethical questions. All of the advances in science have given us the ability to do many wondrous things. But bioethics asks us to question whether we should actually do all of those things.
We can add new genes to an organism’s DNA. We can clone animals. We can extend human life expectancies. We can test people for genetic diseases. But should we, as a society, do all of these things? And who should decide whether we use all of our technological advances? Should these decisions be left to researchers? to universities? to corporations? Should the government make laws to cover bioethical issues? In the end, any decision based on a bioethical question will likely come down to a combination of scientific knowledge, personal values, and law.
Bioethics and Society
Many bioethics issues place an individual’s right to privacy against the right of a company to conduct business, against the need of a community to have access to health information, or against the need of scientists to share research. In March of 2000, for example, Iceland’s government sold the genetic and medical records of its 275,000 citizens to a Swiss drug manufacturer for $200 million. The money helped Iceland’s economy, and any medications or tests for genetic diseases that result from the medical records will be provided for free to all Icelanders.
However, the government’s actions could also be considered to be very troubling. Even though the citizens were given the option to not be included in the database, were the Icelanders’ rights to privacy over their genetic records violated? Does anyone other than the individual have the right to be given access to this very personal information?
Health insurance applicants are screened for preexisting conditions, such as HIV. If a condition is found, companies might offer insurance to a person at a higher cost. Should insurance companies be allowed to do genetic screening to detect whether people have genes that might increase their risk of developing cancer or alcoholism? If not, should healthy people have to pay more to make up for higher costs the company has to pay for people who refuse to be screened? From the company’s point of view, its responsibility is to make a profit for its shareholders. With genetic testing, the company can protect itself from potentially large costs. As you can see, a company’s policy based on its ethics may differ from what others see as ethical.
Science alone cannot answer bioethics questions. When these questions arise, we all need to weigh the issues for ourselves. As biotechnology continues to advance, you will face new bioethics questions throughout your lifetime. Will you be ready?
Questions to Consider
- Should scientists do all of the things that technology has made it possible for them to do?
- Who should decide how biotechnology is used?
- Should scientific knowledge and personal beliefs play equal or unequal roles in decisions about biotechnology?

Technology
Genetic Testing
Genetic testing is used in many ways. We can identify disease-causing genes, determine the guilt or innocence of crime suspects, and reunite families that have been separated. But should genetic testing be used by employers to make decisions about employees?
Suppose that a company secretly obtained and tested DNA samples from some of its employees. Because of rising medical insurance claims, the company wanted to know if the employees had a gene that increased their risk for developing a certain medical condition. Does this seem like a plot for a television show? It isn’t. In 2002, a company had to pay more than $2 million in damages for testing the DNA of employees without their knowledge.
Consider another case. In 2005 a basketball player named Eddy Curry missed the end of the season due to a potential heart problem. His team wanted to use a genetic test to find out if he had a life-threatening condition. Curry refused because the test results could have ended his career. The team refused to let him play. Both the team and Curry made choices. Who do you think was right?
Careers
Geneticist in Action
Dr. Charmaine Royal
Title: Professor, Pediatrics, Howard University
Education: Ph. D., Human Genetics, Howard University
Many bioethicists focus on the ethical implications of technology. Dr. Charmaine Royal, however, is concerned with the ethics of experimental design and the applications and implications of biological research. Dr. Royal, who is a geneticist at the Human Genome Center of Howard University, points out that some scientists in the past tried to use genetic research to justify treating non-Caucasians as inferior. She also notes that although there is no biological basis for any meaningful differences among races, many African- Americans are still suspicious of genetic research. Many, for example, have been discriminated against when an insurance company or a prospective employer finds out they have sickle cell anemia, which is a relatively common genetic disorder in African-Americans.
Dr. Royal, who is Jamaican, wants to ensure that African-Americans are included and treated fairly in research studies, and that they receive the benefits of genetic screening and genetic counseling. In 1998 Dr. Royal helped start the African-American Hereditary Prostate Cancer Study, the first large-scale genetic study of African-Americans to be designed and carried out by an almost entirely African-American research team.

who are we to say we have rights? rights are imaginary and to the government, non-existent so there isn't a lot you can do about it.

I like green pigs..... to me, testing on animals and plants is fine as long as it remains that way and doesn't go as far as testing people.

i think that scientist should decide on biotechnology because they know more than regular people and they should only because too many issues would occur if any one could look at it. Insurance companies would be able to see who is going to get what cancer then they would not let people get certain insurances. Also you would be altering the natural death cycle. Garrett Kazar

I believe that scientists should work on trying to find ways to do anything that can result in helping people. Not everyone should have their records exposed to researchers however. Everyone participating should be volunteers and never forced to participate. If you do not believe in this, you don't have to participate.

Im not quite sure if I agree with this article yet. there is too much to consider and I definately do not agree with testing that could harm animals and/or people. However, I found the article very interesting and enjoyed the comments;)

I loved the article. Yet it is an issue, however for us to live on this planet, will we need to become ruthless and the domiant class of species in the biodiversity of earth. Some people might not like it, even i dont, but the real question is how far will you go to save your lives and the lives of the next generation? nothing in this world is full proof, living is a double-edged sword, this is just another sharp bump that cuts societies fingers around the world. Thats what I got to say, Crow out!

i think its wrong to change genes because then things arent natural. although its different, i think it would make earth more diverse by us creating different species. i dont think that scientists should harm animals for experiments. i do, however think its a good idea to discover different things to help save people.

I believe society should decide on biotechnology. I think this because I think that society would have the most pure answer. What I am saying is is that if you leave this question to leading politicians then either they will disregard it or think of answer that will benefit fit them. Society always has to deal with wrong decisions being made so why don’t we fix this the first time and for once get it right.

i dont mind the idea of testing on animals but i do think that there is a limit and too far is too far. i also dont know who is to say when to far is or who is going to stop scientists when they get there

Changing the genes of an animal isn't natural, and moving on to humans just isn't right. Plus, we've survived without doing this in the past, and I don't think that green pigs will change that.

It is in my opinion that scientists should not do all of the things that technology has enabled us the ability to alternate, although it would be interesting for me to see a purple cat...
Some science experimentation can go too far, and interfere with animal's, plant's and possibly human's natural environments. One specific genetic alteration, and an entire chain of alterations could occur.

In the end, it IS all about ethics. We know we are capable of performing tasks like cloning humans and animals. But is it morally right? If we were to vote, the opinions would be scattered. BECAUSE we have different religions and nationalities all over the country, half of America might say its fine and the other half say no. I believe that our country was founded on God's standards and we should keep it that way.

There is a reason we are what we are right?? But after reading this article I realize biotechnology might be a part of who we are too.

I believe that testing someone's DNA is perfectly acceptable as long as their consent is given. The DNA that is being tested does belong to the subject, and testing without that persons consent should not be allowed.

I believe that when it comes to ethics and biology, ethics is definitely a factor to consider. I'm all for the pursuit of knowledge, and technology, but there should always be a limit. If biotechnology is a harmful risk for humans, and animals then we need to think twice. Society should have a say in how biotechnology is used. After all, biotechnology affects us; society.

Some things are acceptable to perform because of the technology we have, however somethings are just inhumane. I think a person should be able to decide, although I do think that governments should provide guidelines to assure that they do not do things that are too extreme.

I find this article very interesting, although I personally believe we shouldn't test on animals or humans. I do believe we should find out new things be we should test them on animals or humans.

I think that biology needs testing on some species, and many times, you need humans to be tested. If a human is willing to be genetically modified, then there are no bioethics problems.However, if there is a possibility of harm, and if the gene was not tested on something else, humans should not take the risk.

I think that genetic testing is a necessary step that is a silly thing for scientists to not be willing to test. Did you know that during the middle ages, much of the sterilization of scientific studies at the time come from the fact that many things that scientists were wanting to look into were "Unethical", many pretaining to the european churches not allowing the study of things like the organs of the body or the way people work. I think that if we dont take a step like this now, then we are just delaying the inevitable, which may be alot better than you would think.

ok no, although it would be really cool to have like a green pig, these animals do not deserve to be tested on, just as humans do. and ever since they cant talk and argue with the matter doesnt mean we should take advantage of them

Should scientists do all of the things that technology has made it possible for them to do? No the reason a kid doesn't touck a stove is because he can burn himself. The reason scientist don't do all the things technology has made possible is because it will soon back fire or cause a huge negative domino effect.
