<ul> <li>Big evolutionary changes happen gradually and not in giant leaps, a team of biologists led by the University of Sheffield have discovered<br /> </li> <li>Using new methodology to study an evolutionary shift in the birthing style of marine snails, experts have been able to answer the long-debated question as to how game-changing innovations like flight, vision, and the bearing of live offspring happened<br /> </li> <li>Understanding the evolutionary origin of these developments is important because they can dramatically change the course of evolution, such as when live-bearing led to the diversification of mammals or feathers helped birds to evolve flight <br /> </li> <li>Biologists will now be able to apply these new methods to other types of adaptation, including thermal tolerance, which must evolve if some species are to survive clima
