Event Description

Studies of fossils, embryos and genes can tell us about the great transformations in the history of life. Here we will show how we leverage discoveries from expeditions to search for fish with arms, legs, and wrists to make hypotheses about the genetic basis of limb origins. Analyses of fin and limb development reveals that many of the genes involved in patterning the wrists and digits of tetrapods are not only present in fish, they are active in specifying the pattern of the distal segment of fins despite the fact that different tissues develop in each organ.
