Sudden origins

by Jeffrey H. Schwartz

The greatest riddle of evolution has been the following puzzle: while Darwin argued that new species emerge through a slow, gradual accumulation of tiny mutations, the fossil record reveals a very different scenario - the sudden emergence of whole new species, with no apparent immediate ancestors. This discrepancy has fueled heated debate among evolutionary theorists and has provided unfortunate fodder to creationists, who see it as proof that evolution doesn't happen at all. Now, in this book, paleoanthropologist Jeffrey Schwartz presents a radical new theory of evolution, which brings together evidence from genetics, paleontology, embryology, and anatomy to solve this great outstanding riddle. Central to the new theory is the recent discovery of a special kind of gene, known as homeobox genes, which can cause dramatic mutations that express themselves suddenly in the form of a new species. Such a new species will appear to have arisen out of thin air, with no lineage of ancestors. Th
