Course Sequence Recommendations for Students Considering the Human Biology, Behavior, and Evolution Concentration

Required Courses:

Students should aim to complete either the LS 1a/LPS A and LS 1b sequence, or LS 50ab, during their first year. Concentrators are required to complete the Sophomore Tutorial in HBBE, usually during Sophomore Spring. Junior year, students normally take a Research Seminar that aligns with their interests (see website for course listings).

Along with the required courses above, students must take a minimum of nine additional courses. Five of these must be HEB courses*, and the remaining four are approved courses in either HEB or related fields, such as Math/Statistics, Physical Sciences, Chemistry, Archaeology, Psychology, Organismic & Evolutionary Biology, Molecular & Cellular Biology, etc. See the HBBE website (below) for more information on qualifying courses.

*Note: three of the HEB courses must fulfill distribution requirements for Evolution, Anatomy/Physiology, and Behavior. Qualifying courses can be found on the HBBE website.

First-Years should take the online Biology and Chemistry placement exams for placement recommendations.

See the HBBE section of the Life Sciences website for more information

Human Biology, Behavior, and Evolution (HBBE)

Evolutionary theory is a pillar of modern science and provides a powerful framework for investigating questions about why humans are the way they are. HBBE seeks to understand how evolutionary forces have shaped our anatomy, physiology, and behavior. Research in HBBE influences the practice of medicine, and also impacts economics, psychology, political science, religion and literature.

Examples of questions in which we are interested:

• How does our gut microbiota influence patterns of disease?
• Why did our species evolve such large brains?
• How can health care be improved by understanding our species’ evolutionary history?
• Why do humans walk upright?
• What psychological, anatomical and physiological traits are uniquely human and why did they evolve?
• Why and how do humans cooperate on such large-scales compared to other primates?
• How has culture and its evolution--including things like music and religion--shaped our species’ biological evolution?
• How does the lifestyle of modern humans (e.g., diet, activity levels) impact our evolutionary trajectory?

Research: This is an exciting time to tackle questions of how evolution made us human, and research in HBBE provides you the opportunity to learn and contribute. HBBE faculty lead projects spanning a spectrum of interests and methods, including analyses of Peabody Museum skeletal collections, fieldwork in the rainforests of Uganda, and lab work in our cutting-edge facilities. Professors work closely with undergraduates for senior theses, research seminars, and other projects. Examples of research opportunities in HEB include:

● human anatomy

● human behavioral ecology

● human and primate nutrition

● human cognition

● reproductive and behavioral endocrinology

● cultural evolution

● evolutionary genetics and phylogenetics

● primatology

● paleoanthropology

HBBE students also do clinical or medical research and integrate it into their learning goals with HBBE. Our students have worked with PIs in the following example institutions:

● Harvard School of Public Health

● Harvard Medical School

● Mass General Brigham

● Dana Farber Institute

● Broad Institute

● Beth Israel Deaconess

● Northeastern University

● Tufts University

● MIT

● others

Options: HBBE provides a general foundation in human and organismic biology as part of the Life Sciences cluster of concentrations. Students interested in human and non-human primate cognition from the perspective of human evolutionary biology may pursue a Mind/Brain/Behavior (honors thesis) track.

We offer students three degree options: the basic non-honors degree, thesis honors, and non-thesis honors. All students take the LS 1a / LPS A, LS 1b sequence (or LS 50ab), a sophomore tutorial, and a junior research seminar.
