Mathematical Biology seminar: “Careful or colorful? The evolution of animal ornaments”

April 27, 2022, 3:10-4:00pm | Zoom

Speaker: Professor Daniel Abrams from Engineering Sciences and Applied Mathematics, Northwestern University.

Abstract: Extravagant and costly ornaments (e.g., deer antlers or peacock feathers) are found throughout the animal kingdom. Charles Darwin was the first to suggest that female courtship preferences drive ornament development through sexual selection. In this talk I will describe a minimal mathematical model for the evolution of animal ornaments, and will show that even a greatly simplified model makes nontrivial predictions for the types of ornaments we expect to find in nature.
