The research is published in the Proceedings of the National Academies of Sciences (PNAS). Paulson School of Engineering and Applied Sciences (SEAS) combines evolutionary biology and developmental genetics with geometry, biophysics and biomechanics to develop a unified understanding of the growth, form and function of finch beaks. This diversity of beak shapes is well studied from an evolutionary and biological perspective, but little is known about how these shapes came to be from a developmental, mathematical and physical perspectives. ![]()
