Evolutionary Endocrinology

Evolutionary endocrinology is a branch of comparative endocrinology that explores how hormonal systems have evolved across different species. It examines how hormones influence behavior, physiology, and development, and how these systems have adapted to various environments over time. By studying differences and similarities in hormonal functions among animals—from insects to mammals—scientists can gain insights into fundamental biological processes and the evolutionary pressures that shape them, helping us understand not just individual species but also the broader picture of life on Earth.
