Textbook Question
Chapter 10, Problem 1CTS
Humans and chimpanzees are more similar to each other genetically than many very similar looking species of fruit fly are to each other. What does this similarity imply regarding the usefulness of chimpanzees as stand-ins for humans during scientific research? What do you think it implies regarding our moral obligations to these animals?

Animal research is a necessary practice in the
world of medical research, allowing scientists to
develop life-saving interventions and to spot
catastrophic problems before new techniques or
products make their way to actual patients.
However, this does not mean that we should
deny that there are serious ethical issues
involved.
Animal testing is not a pretty or pleasant process.
It causes pain and suffering to animal subjects,
and legitimate cases of abuse have been
uncovered by animal rights groups.
Consequently, the practice should be tightly
regulated, and alternative methods should be
employed whenever possible.
• Discuss a specific research study involving
animals that had ethical issues.
• What were the ethical issues involved?
• What could have been done to conduct the
research study differently to avoid these
ethical issues?
The following is an excerpt from a discussion of Principlism, which we have studied. (https://www.encyclopedia.com/science/encyclopedias-almanacs-transcripts-and-maps/principlism)
Consider, for example, the question of what health professionals should do when they discover that a patient infected with the human immunodeficiency virus (HIV) is having unprotected sex with partners who are ignorant of his condition. First, respect for the patient's autonomy supports a policy of medical confidentiality, requiring health professionals not to reveal to others private information discovered in the course of caring for patients. According to this policy, health professionals should do nothing to warn the sexual partners of their HIV-positive patient, as doing so would violate his confidentiality. Second, if there is evidence that public disclosure of the patient's condition would harm him economically, socially, psychologically, or physically, the principle of nonmaleficence would also urge…
Hi! I am interested in getting some help with this question.
This spectacular animal is a Lesser Bird of Paradise, Paradisea minor, from the highlands of Papua New Guinea.
In the context of various evolutionary phenomena we have discussed this semester, why do you suppose:
(a) This bird is confined to New Guinea and two nearby islands? Why would you not expect to find it in the mountains of Borneo?
(b) This spectacular tail presumably attracts predators; why hasn’t natural selection acted to reduce it or camouflage it?

- Humans as individuals have a number of disadvantages compared to other animals. For instance we are not very fast, strong, cannot see well in the dark, have a poor sense of smell and hearing compared to other animals, and we are not very good climbers.

- Respond to the following paragraph below? I've been thinking a lot about the theories of why humans evolved to become bipedal, and have been watching a lot of specials on YouTube. One of the things that interests me, is one of the ancient human ancestors evolved to be a mixed form of bipedal and not. I find that extremely interesting, because at the time that this being lived Africa was still largely covered in dense jungle/forest and the being still has to climb trees. It was the perfect inbetween of humans and apes or chimps. There was still some m grabbing capability in its feet to allow it to imb trees, but was also able to straighten and reach for higher places. In the video the theory is that these primitive apes needed to reach higher food that others weren't able to, and also had to carry the food for longer distances. One thing that continues from this was the African landscape starting to shift from jungle to savana. With walking upright, they took less heat from the sun,…arrow_forwardWHAT MAKES US PEOPLE DIFFERENT FROM ANIMALS?arrow_forwardHow would you summarize your understanding of this topic now?
