Scientists now have the rare opportunity to observe the effects of a transposon that is undergoing a burst of jumping activity in rice. Although each rice plant has approximately 40 mutations caused by new jumps, the activity is mainly benign and may even help the plant respond to environmental stress.

Dr. Nicole King and Dr. Seth Grant join Cold Spring Harbor Laboratory's David Micklos to discuss the evolution of complex, multicellular animals. Remarkably, the molecules that have driven brain evolution, are the same molecules found in simple unicellula
