UNITS OF ADAPTATION AND BIOLOGICAL INDIVIDUALITY

Course Description

Through the 20th Century, evolutionary theory went from focusing on the selection of organisms to thinking about the dynamics of alleles. This shift forced biologists and philosophers to think about the levels and the units on which natural selection acts upon. What this shift has often downplayed however is the question of how to think about multi-species communities (e.g. symbiotic communities) evolving as unified emergent individuals. We will examine how some simple (i.e. clones) and complex biological individuals demand non-standard accounts of evolution by natural selection and how this problem helps us better understand evolution in general. Through this class we will get a better grasp on the problem of units of selection and the problem of biological individuality.
