Ignoble origin for flowering plants.
At a place called Dutch Gap, the researchers found early angiosperms in silty layers deposited along the margins of ancient river channels -- an environment that would have been unstable because of frequent flooding. Paleobotanists have spent years searching for the earliest angiosperm ancestors, but those efforts have failed because researchers have kept the wrong image in mind, say Hickey and Taylor. Instead of looking for large, woody plants, paleobotanists should search for small, weedy vegetation living along riverbanks.
