Biological Sciences

2. Human Biology

09F, 10F: 11

A course designed to help students (biologists and non-biologists) understand the biological basis of human health and disease. The course will emphasize the fundamental aspects of biochemistry, genetics, cell and molecular biology, physiology, anatomy, reproductive biology, and function of various organs as they relate to humans. Particular emphasis will be placed on specific topics in human health and disease and how these issues affect us all individually in our own health and collectively in our international society.

Open to all students without prerequisite. Dist: SCI. Witters.

4. Genes and Society

10S, 11S: 10A

This course is designed for the humanities or social sciences major. It focuses on how our current understanding of genetic mechanisms has led to new biological insights and to the development of powerful technologies with far reaching implications for our society. It is the aim of this course to provide a solid understanding of the mechanisms of molecular genetics and to discuss implications of genetic engineering and related technologies to our every day lives. Although this course will focus on the science, we will also consider the ethical, political, human, and economic impacts of these technologies. Several guest lecturers will provide personal perspectives based on their experiences. The ultimate goal of the course is to provide an understanding of the biology and technology so that students can make informed decisions on issues that continually and increasingly arise in our society.

Open to all students without prerequisite. Dist: SCI. Gross.

6. Dinosaurs

10W: 2A

This course is designed for the non-major. It will cover all aspects of dinosaur biology including their origin and evolution, phylogeny, behavior, physiology, and extinction. Because dinosaurs will be placed in their biological and geological contexts, other topics will include the geological record, the processes of fossilization, and vertebrate evolution in general. Particular attention will be paid to current debates including the origin of birds and mass extinction. The goal of this course is to teach the basic principles of evolutionary biology using dinosaurs as exemplars of evolutionary patterns and processes. Offered in alternate years.

8. Clinical Biomedical Research

09F, 10S: 2A

This course teaches the fundamentals of clinical biomedical research (CBR). The CBR curriculum offers a unique combination of direct involvement in ongoing clinical research studies with a comprehensive didactic program and experience conducting and designing clinical studies. Designated as Academic Associates, the students will spend time in the DHMC Emergency Department (E.D.) playing an integral role in patient identification, enrollment, and data collection for the ongoing clinical research studies. Coupled with this “hands-on” data collection in the E.D., the didactic program consists of weekly classes focusing on research design, data collection techniques, statistical analysis, and scientific poster preparation. At the completion of the course, each student will develop a “mock clinical research study”.

Prerequisites: Biology 12 and 13 and permission of the instructor. Biology 2 and either 29 or Mathematics 10 are also recommended. Dist: SCI. Curtis.

09F: 10, 10A 10W, 10S: 10A 10F: 10, 10A 11W: 10A 11S: 9L

Biology, like all of science, is a problem-solving endeavor. This course introduces students to a major problem in biology and considers it from many different perspectives, viewpoints and biological levels of organization. Along the way, students are exposed to many of the major concepts in biology, from molecules to ecosystems. Each offering will address a different major problem.

Open to all students without prerequisite. Dist: SCI.

In 09F at 10, Life Through Compound Eyes. Insects rule the earth. They are conspicuous occupants of every terrestrial environment in the world. They influence the properties of ecosystems and the biology of all species within ecosystems. There are more species of insects than all other plant and animal groups combined. Furthermore, insects have proven to be ideal organisms for biological study within virtually every subdiscipline of biology.

In this course, we will draw from the treasure of pioneering research that has been conducted with insects to study the most general and important biological theories from all levels of biological organization: biochemical, molecular, cellular, developmental, organismal, population, communities, and ecosystems—and naturally we will do so from the perspective of the evolutionary processes that shape life on earth. Along the way we will also see how the insect body plan and its underlying genome have permitted the breathtaking diversification of insects, and we will note some of the myriad ways in which insects affect the lives of humans in terms of disease, agriculture, and the environment. Berger, Ayres.

In 09F at 10A, Cooperation and Conflict in Biological Systems. Cooperation and conflict arise at all levels of biology—with molecules, cells, organisms and communities. Throughout the term, we will explore several examples of cooperation and conflict in biological systems and examine the cost and benefits of these two opposing forces. We will investigate theories about how cooperation and/or conflict have shaped how life began, the concept of “selfish” DNA, why cells have the structures they have as well as multi-protein complexes driving essential cellular processes. In addition, we will discuss the generation of multicellular organisms, cooperation of different cell types within the organism and examples of cellular competition that arise in specific diseased states such as cancer. We also will consider behavioral interactions among different types of organisms, and the organization of human societies. Ultimately, our goal is to guide students to critically evaluate the different ways that cooperation and conflict shape biological systems and to begin to understand the mechanisms underlying these two forces. Bickel, Calsbeek.

In 10W at 10A, Biology in the News. Biology is relevant to almost all aspects of everyday life.  Some are obvious.  Everyone recognizes that medicine and agriculture clearly have their roots in biology.  However, others are not so obvious to the average person.  Even insurance actuarials, economic policies and nuclear proliferation have their roots in biology.  Each day we will consider the biological underpinnings and implications of a local, national or international news story taken from a broad range of topics.  Dietrich, McPeek.   

In 10S at 10A, LUCA: the Last Universal Common Ancestor. Over the course of the last 4.5 billion years, life has faced a number of challenges, and in response has evolved a number of remarkable innovations to meet those challenges. Incorporating data and perspectives from molecular and cellular biology, macroevolutionary theory, and paleobiology, we will reconstruct the biology of the Last Universal Common Ancestor of all living organisms. Her name is LUCA and unraveling her biology will require us to work within the framework of what it means to be a living cell. We will move forward in time from the origin of life, and backward in time from the remarkable diversity of life present today. We will see that much of LUCA’s biology has left “molecular fossils” in our very own DNA, and we will learn how to read this remarkable fossil record. Peterson, Sloboda.

75. Genomic Circuitry

10S: 10

Many genomes, including the human genome, have been sequenced. Now, increasing attention has turned to a cryptic, yet fundamental component of these genomes: gene circuitry, i.e. the “wiring” that links together activated genes in a genomic program. Specialized DNA sequences determine where and when a given gene is expressed during an organism’s life cycle. These genomic “regulatory” sequences play a major role in basic evolutionary processes. How do regulatory sequences encode differential gene expression? How do they evolve? How do we identify and decode them? This course will investigate these questions as well as landmark papers necessary to understand present and future work in this field. Offered in alternate years.

Prerequisites: One of the following: Biology 39, 43, 45 or 47. Dist: SCI. Erives.
