2003 JAN 27 - (NewsRx.com & NewsRx.net) -- Evolutionary biologists have long been intrigued by how natural selection - the process in nature by which the organisms best suited to their environment are the ones most likely to survive and leave descendants - gradually creates a complex organ such as the eye, heart, or kidney.
Now University of California, Riverside, biologists, David Reznick and Mark Springer, along with Mariana Mateos, research associate at the University of Arizona, have presented in a model system for studying the evolution of complex organs.
