Nathan Young, PhD
Assistant Professor


Dr. Young is an evolutionary biologist with a background in biological anthropology, anatomy and embryology, and developmental biology. Using both classical comparative and modern experimental approaches, Dr. Young's research focuses on the development of the limbs and shoulder, and particularly how the process of morphogenesis has impacted the evolution of uniquely human adaptations like bipedalism and throwing.
