Scientists have believed for years that flowering plants developed about 140 to 190 million years ago. However, recent studies have shown that they bloomed up about 215 million years ago, about 25 to 75 milllion years earlier than previously believed.
Because previous fossil records show that some species that survive off of nectar like wasps and bees showed up around 200 million years ago, this evidence also supports the dates presented by insect fossil records.
The team's findings were published online in the March 15 issue of Proceedings of the National Academy of Sciences, if you wish to read the full experimental findings.
