4 Years On Campus Bachelors Program
The Bachelor of Science in Biosciences with a Major Concentration in Ecology and Evolutionary Biology at Rice University combines broad biological foundations with advanced study of how organisms, ecosystems, and evolutionary processes interact, while requiring substantial independent research experience. It suits students interested in ecology, conservation, biodiversity, environmental biology, evolutionary science, and life-science research, with preparation for graduate, medical, professional, and science-related careers.
Curriculum Structure
Year 1: Students establish the scientific foundation for the degree through BIOS 201 Introductory Biology I, BIOS 202 Introductory Biology II, CHEM 121 General Chemistry I, and MATH 101 Single Variable Calculus I, alongside other university requirements. These courses build core knowledge in biology, chemistry, mathematics, and quantitative reasoning that supports later upper-level Biosciences study.
Year 2: Students progress into more specialized biological and laboratory learning, including BIOS 213 Introductory Lab in Ecology & Evolution and courses in ecology and evolutionary biology. The curriculum also develops the quantitative foundation through STAT 305 Introduction to Statistics for Biosciences or STAT 315 Probability and Statistics for Data Science, preparing students to interpret biological evidence and data.
Year 3: Students deepen their concentration through courses such as BIOS 332 Ecology, BIOS 334 Evolution, and electives including BIOS 338 Analysis and Visualization of Biological Data, BIOS 374 Global Change Biology, or BIOS 423 Conservation Biology. Laboratory options such as BIOS 316 Lab Module in Ecology and BIOS 322 Conservation Biology Lab add practical experience to advanced ecological and evolutionary concepts.
Year 4: The BS culminates in substantial independent research, with students completing at least 9 credit hours through BIOS 310 Independent Research for Biosciences Undergraduates and related undergraduate research or honors research options. Students complete their concentration with a capstone such as BIOS 423 Conservation Biology or BIOS 431 Emerging Infectious Diseases, bringing together scientific knowledge, research, data analysis, and communication skills.
Focus areas
Ecology, evolutionary biology, conservation biology, biodiversity, animal behavior, plant diversity, global change biology, biological data analysis, emerging infectious diseases, field biology, and independent biological research.
Learning outcomes
Students develop broad biological knowledge, advanced understanding of ecology and evolutionary biology, scientific-literature evaluation, experimental design, mathematical modeling, data collection and analysis, and oral, written, and visual science communication skills.
Professional alignment (accreditation)
Rice University is institutionally accredited by the Southern Association of Colleges and Schools Commission on Colleges (SACSCOC) to award baccalaureate, master's, and doctoral degrees; the university does not identify a separate programmatic accreditation for this Biosciences BS.
Reputation (employability rankings)
Rice University was ranked No. 119 globally and No. 29 among U.S. universities in the 2026 QS World University Rankings, which evaluates institutions partly on employability and outcomes. Rice also reported a No. 17 national ranking in the 2026 U.S. News Best Colleges rankings and a No. 15 ranking for Undergraduate Research/Creative Projects, reinforcing the university's research-oriented undergraduate environment.
The Biosciences BS with a concentration in Ecology and Evolutionary Biology gives students substantial hands-on experience through laboratory, field, and independent research work. The BS specifically requires original research, while the concentration includes BIOS 213: Introductory Lab in Ecology & Evolution, followed by options such as Lab Module in Ecology, Tropical Field Biology, Conservation Biology Lab, Field Bird Biology Lab, and Plant Diversity Lab. Students also develop skills in designing experiments, collecting and analyzing data, evaluating scientific literature, and communicating research findings.
Students can build this practical experience through several program-specific opportunities:
The Biosciences BS with a concentration in Ecology and Evolutionary Biology gives students a strong foundation in biology alongside advanced study of ecology, evolution, scientific research, data analysis, and scientific communication. Rice states that the program prepares graduates for graduate, medical, and other professional schools, as well as a broad range of careers in the life sciences.

University–industry connections:
Long-term accreditation value: Rice University is institutionally accredited by the Southern Association of Colleges and Schools Commission on Colleges (SACSCOC) to award bachelor's, master's, and doctoral degrees. Rice's accreditation is subject to comprehensive reaffirmation review, providing an established institutional quality-assurance framework for the BS degree.
Graduation outcomes: Students completing the concentration are expected to demonstrate advanced knowledge of ecology and evolutionary biology, evaluate biological research literature, conduct original research using experiments or mathematical models, analyze and interpret data, and communicate scientific findings effectively to diverse audiences.
Further Academic Progression: After the BS, students can progress into Rice's MS in Ecology and Evolutionary Biology, which requires original research, a master's thesis, a departmental seminar, and a public thesis defense. The BS also provides preparation for Rice's PhD in Ecology and Evolutionary Biology, while students interested in broader environmental careers can pursue the MS in Environmental Analysis, a professional master's program combining environmental science with management, policy, quantitative decision-making, and a required professional internship.
