Comparative Anatomy & Limiting Factors

This document appears to be a student worksheet on the topics of homologous and analogous structures as evidence for evolution. It contains questions asking the student to identify structures as homologous or analogous and give examples. It also asks the student to explain how human, whale and bat structures provide evidence that they belong to a common ancestral group. The worksheet concludes with a section asking the student to identify limiting factors affecting population density as either density-dependent or density-independent.
