Video Title:
Examining the patterns of the evolution of mode of development
Can living things re-acquire characteristics that they once lost? Some species of slipper snails may have re-evolved a free-living larval stage after losing it three million years ago to development that occurs in an egg capsule. Through a grant from the National Science Foundation, Dr. Rachel Collin, from the Smithsonian Tropical Research Institute in Panama, is studying what leads to the "evolutionary potential" to reacquire features and her work will provide new insight into the process of evolution. Video and edition by: Richard Pierce Collin Lab Smithsonian Tropical Research Institute 2011 Research in the Collin Lab focuses on the evolution of life histories and development of marine invertebrates. Our current work, supported by the US National Science Foundation, uses marine slipper limpets (Calyptraeidae) to try to understand the evolutionary loss and possible reacquisition of feeding larvae. The Collin Lab is located in Panama City, Panama, at the Smithsonian Tropical Research Institute's Naos Marine Laboratories, but our field work takes us to various other countries in the Americas. We hope that the videos on this YouTube channel give you an introduction to the faces in the Collin Lab, as well as a taste of the kinds of projects we are working on.
