Biology

Biology is the study of life in its broadest sense, ranging from topics such as the role of trees in affecting global atmospheric carbon dioxide down to the molecular mechanisms that switch genes on and off in human brain cells. Biology includes a tremendous variety of disciplines: molecular biology, genetics, anatomy, physiology, microbiology, behavior, evolution, ecology, developmental biology, immunology, and many others. Because Sarah Lawrence College faculty members are broadly trained and frequently teach across the traditional disciplinary boundaries, students gain an integrated knowledge of living things—a view of the forest as well as the trees.

In order to provide a broad introduction and foundation in the field of biology, it is strongly recommended that students begin with the gateway course, General Biology: Genes, Cells and Evolution, in the fall semester. Other open-level courses—such as Botany, Ecology, or Human Genetics—may also be considered, depending on the targeted nature of the student’s interests.  Students should consult with the biology faculty to help determine their appropriate course. Completion of any two biology courses with labs fulfills the minimum biology curriculum requirements for medical school admission. General Biology: Genes, Cells and Evolution typically meets the prerequisite needs for further intermediate-  and advanced-level study in biology, as well.

    As the frontiers of science are pushed forward, conflicts naturally emerge between new hypotheses and established ideas. Biology is no exception to this rule. Since the time of the ancient Greeks, new proposals examining the biological nature of humans and the living world have initially met with resistance and even ridicule before becoming established as modern paradigms. What appears obvious now was once regarded as revolutionary, while it is conceivable that our current ideas will be regarded someday as bordering on the absurd. Oftentimes, these conflicts arise not only due to the convergence of scientific principles but also result from personality clashes of the individuals involved in the research area. Paradigm shifts have occurred in a variety of biological fields, ranging from early ideas on heredity, sex determination, and evolution to more recent advances in prions and vaccines, animal model usage, genetic engineering, cutting-edge cancer therapies, and the interplay between genes and environment. Using these and other examples, we will examine the progress of biological thought and the persistence of the scientific method in changing our understanding of life. In fall, students will meet weekly with the instructor for individual conferences. In spring, individual conferences with the instructor may be weekly or biweekly.

    Ecology is a scientific discipline that studies interactions between living organisms and their environments, as well as processes governing how species are distributed, how they interact, and how nutrients and energy cycle through ecosystems. Ecologists might ask questions about how plant growth responds to climate change, how squirrel population size or behavior changes in response to acorn availability, or how nutrients like nitrogen and phosphorous cycle in rivers and streams. In this course, students will develop a strong foundational understanding of the science of ecology at the individual, population, community, and ecosystem scales. Throughout the course, emphasis will be placed on how carefully-designed experiments and data analysis can help us find predictable patterns despite the complexity of nature. Students will be expected to design and carry out a field experiment, either individually or in small groups. The course will include a weekly lab, with most labs held outdoors.

    Biology, the study of life on Earth, encompasses structures and forms ranging from the very minute to the very large. In order to grasp the complexities of life, we begin this study with the cellular and molecular forms and mechanisms that serve as the foundation for all living organisms. The initial part of the semester will introduce the fundamental molecules critical to the biochemistry of life processes. From there, we branch out to investigate the major ideas, structures, and concepts central to the biology of cells, genetics, and the chromosomal basis of inheritance. Finally, we conclude the semester by examining how those principles relate to the mechanisms of evolution. Throughout the semester, we will discuss the individuals responsible for major discoveries, as well as the experimental techniques and process by which such advances in biological understanding are made. Classes will be supplemented with weekly lab work.

    Plants are all around us and are essential to life on Earth but are often overlooked or taken for granted. Especially as climate change and habitat loss threaten global biodiversity, understanding the biology of plants is fundamental to understanding the complex web of life on Earth. This course will be an introductory survey of botany. The first half of the course will cover topics such as plant anatomy, morphology, physiology, and reproduction; the second half will explore plant genetics, diversity, ecology, and evolution. Weekly discussions and textbook readings will be complemented by lab activities and a field trip to the New York Botanical Garden.

    BIOL 3617

    Note: This course is appropriate for any student who has completed International Baccalaureate, Advanced Placement biology, or a previous college-level biology course.

    At the biological core of all life on Earth is the gene. The unique combination of genes in each individual ultimately forms the basis for that person’s physical appearance, metabolic capacity, thought processes, and behavior. Therefore, in order to understand how life develops and functions, it is critical to understand what genes are, how they work, and how they are passed on from parents to offspring. In this course, we will begin by investigating the theories of inheritance first put forth by Mendel, then progress to our current concepts of how genes are transmitted through individuals, families, and whole populations. We will also examine chromosome structure and the mechanisms and molecular functions of genes and DNA within cells, as well as how mutations in DNA can lead to physical abnormalities and diseases such as Trisomy 21, hemophilia, or others. Finally, we will discuss the role of genetics in influencing complex phenotypes such as behavior or traits such as intelligence. Classes will be supplemented with weekly lab work.

    This course is designed to introduce students to the ways in which scientists use engineering tools to interrogate basic biology. Students with knowledge of basic biology will gain a deeper understanding of disease processes through current research in the biomedical engineering field. The course is designed around primary research in the field: The first class of the week will be a lecture covering background information, and the second class will consist of a peer-led discussion of a current research article. Students will aim to answer the following guiding questions: What is the main finding of this research? How does this work advance the field? What future experiments would you propose related to this research? We will cover topics including biomechanics, medical imaging, tissue engineering, drug delivery, immunoengineering, and cancer applications of bioengineering.

    The immune system is comprised of several components that together protect us from non-self, foreign pathogens, as well as from self-dangers like cancer. We are surrounded by billions of microbial pathogens that live inside and on our bodies, and the immune system is continuously at war with these tiny invaders. The first line of defense is the innate immune system, which gets activated at the first exposure to foreign substances and sounds an alert for the adaptive immune system to respond. Together, the innate and adaptive immune systems form a complex biological system that has evolved throughout evolution to protect us from infections and diseases. In this course, we will focus on the understanding of the fundamental concepts of immunology, which will also include how these concepts apply to diseases. Immunology is a complex subject with numerous concepts and terminology; therefore, to be successful in this course, the lectures will be complemented with quizzes/assignments, group discussions, and an oral presentation in order to enhance the learning process.

    Knowledge of anatomy (structure) and physiology (function) are critical to understanding how an organism maintains homeostasis. Systems must work in concert to ensure proper health of an individual. Students will learn about the respiratory, cardiac, endocrine, digestive, musculoskeletal, nervous, and reproductive systems. This course will cover how structure leads to function, along with the diseases that occur following anatomical/physiological dysregulation. Emphasis will be placed on contextualizing information as it relates to medical applications. Conference work will consist of a literature review on a student-selected disease process and its related physiology.

  • Open, Lecture—Spring | 5 credits

    BIOL 2166

    Note: Closed to students who have taken Biology of Cancer (BIOL 3766).

    Approximately 39% of men and women will be diagnosed with cancer at some point during their lifetime, according to the National Cancer Institute. To respond to this pervasive and devastating disease, Congress approved The Cancer Moonshot program in 2016 (and 2022), aimed at accelerating cancer research, prevention, screening, and treatment. But what is cancer? What causes cancer? Why is it so diverse, persistent, and deadly? How do we treat cancer? Can we ever find the "cure" for cancer? This course aims to demystify cancer and provide students with a fundamental understanding of the disease. We will explore the basics of cell biology and how these processes are disrupted, or co-opted, during cancer development. Additionally, this course will highlight foundational and modern treatment strategies and why the process of developing new treatments takes so long. While the course will be firmly rooted in the underlying biology of cancer, no prior college-level biology is required. Students who are interested in understanding cancer or deepening their knowledge of biology are encouraged to take the course.

    Neuroscience is the science of what makes us who we are. Our sensations, emotions, movements, sleep, memories, and other complex behaviors all arise from the nervous system. This course will explore how cellular, molecular, and network mechanisms make these behaviors not only possible but seemingly effortless. We will begin with functional neuroanatomy, tracing a paradigm shift from viewing the brain as a patchwork of specialized regions to understanding it as a dynamic, probabilistic system of interconnected networks. Next, we will examine how neurons transmit information and how our conception of neural function has evolved from seeing neurons as narrowly specialized units to recognizing them as plastic, broadly tuned cells capable of responding to diverse stimuli. We will also explore how the brain generates sensations, perceptions, and illusions that allow us to navigate, learn from, and adapt to our environment. This knowledge extends to the endocrine and immune systems, which continuously interact with the brain to regulate behavior. Finally, the course will consider higher-order cognitive functions and examine how disruptions at molecular, cellular, or systems levels can lead to neurological and neuropsychiatric disorders. Approaches to restore or enhance brain function—from pharmaceutical treatments to brain-computer interfaces—will also be discussed. Students will engage in active learning through in-class, small-group exercises that complement lecture material. By the end of the course, students will have a solid understanding of the principles of neuroscience and prepare them for further study in neuroscience, physiology, and medicine.

    Prerequisite: General Biology: Genes, Cells, and Evolution (BIOL 2014) or Genetics (BIOL 3617) or equivalent

    Cells are the most basic unit of life on the planet; all life forms are simply conglomerations of cells, ranging from the individual bacterial cells to higher order plants and animals. Humans, themselves, are made up of trillions of cells. So what exactly is a cell? What is it made of? How does it function? In a complex organism, how do cells communicate with one another and coordinate their activities? How do they regulate their growth? What role do genes play in controlling cellular function? This course will address these questions and introduce the basic biology of cells while also keeping in mind their larger role in tissues and organs. If we can understand the structures and functions of the individual cells that serve as the subunits of larger organisms, we can begin to understand the biological nature of humans and other complex life forms. Classes will be supplemented with lab work.

    Humans are bathing in a sea of microbes. Microbes coat our environments, live within our bodies, and perform functions both beneficial and detrimental to human well-being. This course will explore the biology of microorganisms, broadly defined as bacteria, archaea, viruses, single-celled eukaryotes, and fungi. We will study microbes at multiple scales, including the individual cell, the growing population, and populations interacting with one another or their environments. Microbial physiology, genetics, diversity, and ecology will be covered in depth. Particular emphasis will be given to the role of microbes that cause infectious disease in humans and microbes that play critical roles in ecological processes. Seminars will be supplemented by a weekly lab section to learn key microbiological techniques and methods, most notably culturing and identifying bacteria.

    Prerequisite: prior course work in botany or ecology or permission of the instructor

    With more than 350,000 known species, plants form the foundations of ecosystems and are crucial to life on Earth. This course will examine the diversity, ecology, and evolutionary history of major land plant groups—bryophytes, ferns, lycophytes, gymnosperms, and angiosperms. Through lectures, discussion of scientific literature, and hands-on investigation of live and preserved material, students will learn how to decipher botanical terminology; identify major plant families using diagnostic characters and dichotomous keys; analyze evolutionary relationships and adaptations across plant lineages; and investigate plant interactions with fungi, bacteria, animals, and their environment.
