Introduction to Evolution

The objective of this course unit is to understand evolutionary processes at both the micro- and macro-evolutionary scales.

Using examples, hands-on activities, and accessible modeling, the course will aim to present, in a concrete and quantitative way, the effects of the four evolutionary forces operating at the individual and population levels (mutation, migration, selection, and genetic drift). The integration of these microevolutionary processes into larger timescales (e.g., lineage differentiation, speciation) will then be addressed. Finally, the course unit will include an introduction to phylogenetic tools (interpreting and constructing phylogenetic trees) that enable the study of macroevolutionary events (diversification, extinction) and the tracing of changes in character states, particularly by incorporating fossil data.
