Final answer:
Scientists who study evo-devo engage in research in the fields of embryology, comparative psychology, and ethology. Embryology examines the development of organisms from embryo to adult form and provides evidence of relatedness between diverse groups of organisms. Comparative psychology and ethology contribute to the study of behavioral biology.
Step-by-step explanation:
Scientists who study evo-devo engage in research in the fields of embryology, comparative psychology, and ethology.
Embryology, a branch of biology, examines the development of organisms from embryo to adult form. It provides evidence of relatedness between diverse groups of organisms. For example, vertebrate embryos, including humans, exhibit gill slits and tails during early development.
Comparative psychology is the study of animal behavior, while ethology focuses on the natural behavior of animals in their natural habitats. Both fields contribute to the study of behavioral biology and unravel the factors influencing behavior in different species.
