The multidisciplinary research in Al’s lab combines fossils and modern biotechnology to demonstrate some of the limits on evolution. This has included discovering a rule of how teeth evolve that shows humans are constrained in the same way as mice – both show the same evolutionary trends and limitations. Al has also invented a new technique for predicting the diet of extinct animals by using state-of-the-art 3D imaging to measure the complexity of teeth. This new method opens up a window on the past diversity of life. Another avenue of research has been the speed of evolution, where he has demonstrated how long it takes to evolve an animal the size of a mouse into one the size of an elephant.

Logarithmic spiral (dashed blue curve). For this spiral, the radius grows by a factor of 1.1923 per 1 radian of angle. It is not an exact fit to the Nautilus, being off if different directions in different parts, but is a good approximate fit. Credit: Wikimedia Commons.
