1. Ancestry and Lineages in Complex Evolution and Classification - The concepts of "ancestry" and “lineages” are taken for granted in many biological and philosophical discussions, but a closer look suggests that they have different meanings, scientific roles, and ontological assumptions depending on the context. These differences have significant ramifications for biology and philosophy, such as the idea that there are multiple kinds of lineages in nature. Additionally, complex cases of micro and macroevolution challenge the role of lineages, ancestry, and related concepts in evolution and classification.    
2. Race and Values - Are races real? Social values influence the answer of philosophers, scientists, and citizens to this question. For instance, recent defenses of biological racial realism are pluralistic: one accepts that more than one concept of race is legitimate. But how can we distinguish legitimate from illegitimate concepts of race? I consider how social values should play a role in answering this question. In particular, I investigate how philosophical argumentation (about race) itself depends on social values.
