The Anthropology of Biology

Rating
0.0 stars

This course applies the tools of anthropology to examine biology in the age of genomics, biotechnological enterprise, biodiversity conservation, pharmaceutical bioprospecting, and synthetic biology. It examines such social concerns such as bioterrorism, genetic modification, and cloning. It offers an anthropological inquiry into how the substances and explanations of biology—ecological, organismic, cellular, molecular, genetic, informatic—are changing. It examines such artifacts as cell lines, biodiversity databases, and artificial life models, and using primary sources in biology, social studies of the life sciences, and literary and cinematic materials, and asks how we might answer Erwin Schrodinger’s 1944 question, “What Is Life?” today.

Antibiotics save people’s lives...and make bacteria stronger and more likely to kill us.  What is the best practice to balance these conflicting issues? In this problem-based learning module, the students will be evaluating real-life medical situations in conjunction with actual staff at those institutions and offering action plans to be ‘implemented’ there.  In order to accomplish this, the science unit will be interlocking with social studies and a language arts unit that will have them identifying target audiences and sculpting a way to present their findings.  This unit has the potential to be a full problem-based unit as well as highly interdisciplinary--it’s connected to full units in social studies and language arts which stand alone but can be fully integrated if desired.

Students construct paper recombinant plasmids to simulate the methods genetic engineers use to create modified bacteria. They learn what role enzymes, DNA and genes play in the modification of organisms. For the particular model they work on, they isolate a mammal insulin gene and combine it with a bacteria's gene sequence (plasmid DNA) for production of the protein insulin.

Students toss coins to determine what traits a set of mouse parents possess, such as fur color, body size, heat tolerance, and running speed. Then they use coin tossing to determine the traits a mouse pup born to these parents possesses. Then they compare these physical features to features that would be most adaptive in several different environmental conditions. Finally, students consider what would happen to the mouse offspring if those environmental conditions were to change: which mice would be most likely to survive and produce the next generation?

Bioethics is the study of the moral implications of new and emerging medical technologies and looks to answer questions such as selling organs, euthanasia and whether should we clone people. The series consists of a series of interviews by leading bioethics academics and is aimed at individuals looking to explore often difficult and confusing questions surrounding medical ethics. The series lays out the issue in a clear and precise way and looks to show all sides of the debate.

Biochemistry: Free For All

We are happy to welcome you to our second Open Educational Resource (OER) textbook, Biochemistry Free For All. Biochemistry is a relatively young science, but its rate of growth has been truly impressive. The rapid pace of discoveries, which shows no sign of slowing, is reflected in the steady increase in the size of biochemistry textbooks. Growing faster than the size of biochemistry books have been the skyrocketing costs of higher education and the even faster rising costs of college textbooks. These unfortunate realities have created a situation where the costs of going to college are beyond the means of increasing numbers of students.

This exercise contains two interrelated modules that introduce students to modern biological techniques in the area of Bioinformatics, which is the application of computer technology to the management of biological information. The need for Bioinformatics has arisen from the recent explosion of publicly available genomic information, such as that resulting from the Human Genome Project.

Biology is the science that studies life, but what exactly is life? This may sound like a silly question with an obvious response, but it is not always easy to define life. For example, a branch of biology called virology studies viruses, which exhibit some of the characteristics of living entities but lack others. It turns out that although viruses can attack living organisms, cause diseases, and even reproduce, they do not meet the criteria that biologists use to define life. Consequently, virologists are not biologists, strictly speaking. Similarly, some biologists study the early molecular evolution that gave rise to life; since the events that preceded life are not biological events, these scientists are also excluded from biology in the strict sense of the term. From its earliest beginnings, biology has restled with these questions: What are the shared properties that make something “alive”? And once we know something is alive, how do we find meaningful levels of organization in its structure?

Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.
