For many years, Charles Darwin was haunted by flowers. In 1859, the naturalist published his most famous work, On the Origin of Species, the book that is generally regarded as the foundation of ...

Recent advances in molecular phylogenetics and a series of important palaeobotanical discoveries have revolutionized our understanding of angiosperm diversification. Yet, the origin and early ...

Here we discuss recent advances surrounding the origin of angiosperms. Putatively primitive characters are now much better understood because of a vastly improved understanding of angiosperm ...

Two species of aquatic angiosperms, Aquatifolia fluitans gen. et sp. nov. and Brasenites kansense gen. et. sp. nov., are reported from the Hoisington III locality, Barton County, Kansas. On the basis ...

International Journal of Plant Sciences, Vol. 161, No. S6, Current Perspectives on Basal Angiosperms (November 2000), pp. S97-S107 (11 pages) Patterns and trends in angiosperm evolution can only be ...

Fossils of angiosperms first appear in the fossil record about 140 million years ago. Based on the material in which these fossils are deposited, early angiosperms must have been weedy, fast-growing ...

The discovery of exceptionally well-preserved, tiny fossil seeds dating back to the Early Cretaceous corroborates that flowering plants were small opportunistic colonizers at that time, according to a ...

They are very tiny, but they are a key source of information when it comes to Earth's evolutionary history: pollen grains are usually no larger than 20 micrometers, or 0.02 millimeters. Using these ...

Plant powerhouses Fossil evidence confirms that the first rainforests sprang up around 65 million years ago when a boost to flowering plants' plumbing system turned them into photosynthesising ...

A tiny flower pressed between layers of sandstone for more than 160 million years could be the oldest flower fossil ever found, a new study reports. However, not everyone agrees that the fossil ...

When the world's first flower sprouted about 140 million years ago, it was bisexual, possessing both male and female reproductive parts, according to the researchers who virtually reconstructed the ...
