 In frogs, the first sensory neurons that develop play a role in the animals hatching response. Heathcote, a professor of biological sciences, and graduate student Peter Feud want to know what guides the development of sensory neurons, so they will fertilize eggs to create embryos. |  Professor David Heathcote sticks his hand into the space-age looking tanks that hold collections of Xenopus laevis-African clawed frogs. |  Usually a dark brown color, David Heathcote's collection of frogs include a single albino. |
