Conquest of land began in shark genome
Date:8/14/2007

ginous skeletons and bony fish more than 135 million years before digits debuted in the earliest limbed animals.

The leap from aquatic life to terrestrial life is an extremely dramatic, important point in evolution that has captured the interest of many, said Marie Kmita, Ph.D., director of the Genetics and Development Research Unit at the Institut de Recherches Cliniques de Montral who was not involved in the research. Understanding how changes in gene regulation modify the body architecture is of extreme interest to scientists who are trying to find ways to improve human health by learning from developmental processes. This work shows a late phase of gene regulation seems fated to the emergence of digits.?
