Evolution of the mammalian baculum

点击翻译按钮获取中文摘要

This project aims to test the hypothesis that the shape of the mammalian baculum (penis bone) evolved via its stimulatory effects on females that promote reproduction. The baculum is the most morphologically divergent bone in the mammalian body. The reason for this divergence is one of the most puzzling enigmas of mammalian morphology. This project will use comparative evolutionary methods, quantitative genetics, morphometrics, behavioural analysis and techniques from neurobiology and physiology to test this hypothesis. This project aims to address fundamental questions in reproductive biology.
