Biology needs to look beyond genomes now, says an expanding group of evolutionary biologists who are pushing for a new initiative. They want to build a "tree of life" that would map the evolution of Earth's species and show how they split off from one another over time. The project, which would make use of genetic and morphological data, might be more expensive than the human genome project and take longer to complete. But it would be well worth the effort, they say.
