New Genetic Study Helps to Solve Darwin's Mystery about the Ancient Evolution of Flowering Plants (IMAGE)
Caption
The evolution and diversification of the more than 300,000 living species of flowering plants may have been "jump started" much earlier than previously calculated, according to a new study led by Penn State Unviersity scientist Claude dePamphilis. The study provides a wealth of new genetic data and is expected to change the way biologists view the family trees of plants in general and flowering plants in particular. This image illustrates the two major upheavals in the plant genome that the dePamphilis study reveals occurred hundreds of millions of years ago -- nearly 200 million years earlier than the events that other research groups had described.
