Morphometrics: Quantifying Shape to Unlock Evolutionary Secrets

Morphometrics: Introduction to the Analysis of Shape

I explore how morphometrics uses quantitative methods like Principal Components Analysis to study biological form. We examine landmarks, phylogenetic independent contrasts, and the distinction between functional traits and spandrels. Using tools like R and PAST, we can rigorously test hypotheses about evolution and biomechanics while avoiding statistical pitfalls caused by shared ancestry.
