Understanding Evolution in Natural Systems Using Models


Applications can be submitted to the Office of Research until 4pm on 29/06/2018.

Our research focuses on the relationship between form, function and ecology of living and extinct animals. One fundamental goal in evolutionary biology is to understand how size can constrain the evolution of morphological traits and limit the ability to exploit ecological niches. Size influences all
biological functions from cellular respiration, up to how fast an animals can run or climb. We will study this using computational musculo-skeletal modelling in OpenSim.

The PhD project will contribute to research that investigates the neuromuscular and biomechanical mechanisms associated with changes in body size using varanid lizards as a model. We have collected an extensive morphological dataset for this group including the muscle architecture of varanid lizards ranging from the smallest (7.6 g Varanus brevicauda) to the largest extant species (40 kg Varanus komodoensis), as well as their maximum speeds. We will use musculoskeletal models of varanid lizards in OpenSim to predict higher level biological parameters (e.g. running speed) in both living and extinct species. We will be able to scale our model up or down, exploring size, or change its shape (e.g. limb length). This will allow us to understand what the limitations to size are, in biological systems, and at what size certain structures no longer work. This research will have direct implications for understanding evolution as a process of optimisation.
