Converging on the Web

Simon Conway Morris is one of the world’s top biologists and a leading scholar of evolutionary convergence, the idea that all life evolves toward similar adaptations, using very different routes. With grant support from the Foundation, the Cambridge University paleobiologist recently launched Map of Life, a comprehensive Web resource for students, academics, and other readers curious to learn more about convergence. Not only is this website intended to be as informative as possible about convergence, it also aims to remind both scientists and the public that while the fact of evolution is beyond dispute, the apparently surprising fact that many features in the biological world evolved again and again suggests that the pathways of evolution are more constrained than is generally thought to be the case. As the Map of Life site explains, “Through the surprisingly ubiquitous process of convergent evolution, organisms as distantly related as moths and birds, ciliates, and worms, when inhabiting similar environments, have developed similar features as adaptive solutions to life there. This suggests that evolutionary outcomes can be much more predictable than generally thought, and raises interesting questions about how patterns of convergence arise.” Through this engagingly interactive and scientifically rich Internet site, Conway Morris and his Cambridge-based team are eager to raise the profile of convergence in public discussions about evolution.

“Convergence suggests, at least to some persons, that evolution is not a completely random, patternless process and that if you could rerun the history of life it would not be unrecognizably different each time,” says Andrew Rick-Miller, a senior program officer at the Foundation. “For Sir John’s interest in big questions about purpose and meaning, including the possibility you could discern them in biological systems, the prevalence of convergence is potentially very fruitful.”
