...Farish A. Jenkins Jr., professor of biology and Agassiz professor of zoology, along with Neil H. Shubin, professor of organismal biology and anatomy at the University of Chicago, and Edward B. Daeschler of the Academy of Natural Sciences in Philadelphia formed the core group of scientists who made the discovery in the Canadian Arctic Archipelago...
...Digging in Madagascar, an international team headed by John Flynn of Chicago's Field Museum has unearthed the fossil jaws of two dinosaurs that appear to be around 230 million years old. "These are either the earliest or among the earliest dinosaurs known," comments University of Pennsylvania paleontologist Neil Shubin. The scientists also found fossils of eight other primitive animals, some of which are a key to the evolution of mammals, which arose at about the same time as the dinosaurs...
Together, the remains open an unprecedented window into a time when nature was setting the stage not only for dinosaurs but also for the age of mammals that followed--and the eventual rise of the human species. Says Shubin: "If you look at the major groups of animals in the world today--mammals, crocodiles, turtles, frogs--most appeared during the Triassic, 220 million to 200 million years ago." With new discoveries making the origin of these groups ever more remote, he adds, "any find dating to this period is clearly very crucial...
...homoeotic homeobox genes, or Hox genes for short -- lay out the embryo from head to tail, controlling everything from the development of limbs and the wiring of the spinal cord to the patterning of the gut and urogenital tracts. "What's amazing," says University of Pennsylvania paleontologist Neil Shubin, "is that evolution of complex structures appears to be controlled by this same small set of genes...
...mayor of Mudanjiang, Wang Shubin, wants to talk not about the soldiers but about local merchants, who have their own interest these days in the Soviet Union. Beijing and Moscow have authorized the Chinese province of Heilongjiang and the Soviet Union's Maritime province to conduct direct cross- border trade. Chinese and Soviet officials travel back and forth, comparing wish lists, displaying wares and negotiating barter deals. Since both countries have nonconvertible currencies and neither wants to expend precious reserves of hard currency, no money changes hands. The Chinese supply vegetables, prefabricated plastic greenhouses and textiles; the Soviets send back...
