The BSc in Evolutionary Biology is a four-year course run by the School of Biology. Evolutionary Biology at St Andrews provides students with high-tech equipment, laboratories and expertise to facilitate learning and to develop the skill set of a modern evolutionary biologist.

In first year and second year, modules introduce the students to core subject material relevant to all degree programmes in areas such as animal and plant biology, molecular biology, cell biology and genetics.

Alongside biology, in the first year of their studies, they will be required to study an additional two subjects. In the second year they will usually carry on at least one of these subjects, sometimes two. In the third year, there is a shift from core, broad-themed modules to more specialised modules which allow students to prepare for their Honours degree. In fourth year students continue specific research in their chosen area through student-led, enquiry-based learning.

The University of St Andrews operates on a flexible modular degree system by which degrees are obtained through the accumulation of credits.
