Abstract/Description: I describe the interspecific variation of the wings and legs across 31 different species of Drosophila. This project is an expansion of previous work on the interspecific variation of Drosophila wings (Houle et al., 2017). I wanted to understand if the wings and legs have similar rates of evolution. Using the ordinations of the wing and leg traits, I saw the trend that similarly related taxa were grouped more closely together when using the wing traits. Phylogenetic heritability scores indicated that the wing traits follow the phylogeny better than the leg traits. These two findings were indirect evidence that the rates of evolution are different between the two appendages. A phylogenetic mixed model found that the leg traits are evolving more rapidly than the wings. There may be several ecological or developmental explanations for these findings. This project has the potential to better describe how development affects the evolutionary rates of different appendages. More importantly, this document can provide some insight into how to compare the rates of divergence in an interspecific model system.
