Mass media have recently reported that modern science is already capable of resurrecting dinosaurs. As a matter of fact, it is impossible to resurrect the lizards that became extinct 65 million years ago. However, it is possible to create new ones.
Is it possible to prevent the deactivation of the genes? Scientists from McGill University under the direction of Hans Larsson discovered that the gallinacean (chicken) embryo has a reptile-like tail during the early stage of development. The activity of the genes responsible for the formation of this tail stops at a certain moment, and the tail disappears.
Dr. Larsson and his colleagues were trying to block the activity of the proteins that deactivate the tail genes. The scientists succeeded in the end, but the "tailed" chicken died before it was formed completely.
