Why I Am a Naturalist

Ellen Ketterson

Posted on

I am an integrative evolutionary biologist who has focused on the role of hormones in phenotypic variation and the role of ‘hormonal pleiotropy’ in maintaining the tension between independence and interdependence in the evolution of correlated traits. I have been a member of the American Society of Naturalists for many years, and the papers I have written that provide me with the most satisfaction have appeared in issues emanating from ASN Vice-Presidential symposia.
