The Origin of Flowers

Magnolia campbellii 'Borde Hill' (British Columbia Botanical Garden)

Earlier studies had suggested that flowering plants – angiosperms – first arose 140 million to 190 million years ago: a result which seemed paradoxical in light of the evidence that many of the modern insect species such as bees and wasps, which rely upon flowering plants for pollen and nectar, appeared much earlier in the fossil record.

But a new study appearing in the Proceedings of the National Academy of Sciences moves the age of flowering plants back to 215 million years ago, much more commensurate with the evidence for interdependent insect species. EurekAlert! has more in Molecular Study Could Push Back Angiosperm Origins.

Update: Here’s the abstract for the original article appearing in the Proceedings.
