Route map
This chapter consists of three broad sections. The first is an introduction to the psychobiological perspective and its diversity. The second examines the scientific nature of animal experiments and the use of animals in research within the UK. The third section focuses on evolution and genetics. The process of evolution suggested by Darwin explained how the process of natural selection influences subsequent generations; Mendelian genetics helped clarify how this process occurs and modern molecular biology has narrowed the focus to individual genes on chromosomes.
