*In a new paper published in Science, we show that the tail could have provided a crucial advantage to early tetrapods taking their first steps onto sandy or muddy substrates. Tail use improves soft substrate performance in models of early vertebrate land locomotors
Our research addresses problems in nonequilibrium systems that involve interaction of physical and biological matter with complex materials (like granular media) that can flow when stressed. For example, how do organisms like lizards, crabs, and cockroaches generate appropriate musculoskeletal dynamics to scurry rapidly over substrates like sand, bark, leaves, and grass. The study of novel biological and physical interactions with complex media can also lead to the discovery of principles that govern the physics of the media. We integrate laboratory and field studies of organism biomechanics with systematic laboratory studies of physics of the substrates, create models of the substrates, and create mathematical and physical (robot) models of the organisms.
