Where Fossils Fear To Tread: Scientists Follow Genes To An Ancient Ancestor
...es like the land. During the Cambrian, animals got bigger
and more diverse, but those changes did not require new genes. The techniques being pioneered by Carroll and others are opening a new window to the past, said Carroll: "It's doing paleontology without fossils."...
