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

Red, white and blue flowers help color the July Fourth patriotic season, including these red and white pentas (and their unexpected guest, a giant leopard moth) and a blue lace-cap hydrangea. Kat ...

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 ...

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 ...

Paleontologists may be on the verge of solving one of the great mysteries in the history of life on our planet – the origin of angiosperms, the flowering plants. The importance of angiosperms cannot ...

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 ...

This is a preview. Log in through your library . Abstract Genome size varies extensively across the flowering plants, which has stimulated speculation regarding the ancestral genome size of these ...

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 ...

ARGUABLY the world’s weirdest plant, Welwitschia mirabilis is a tangled mass of shredded, fraying leaves in the Namib desert. For a thousand years, perhaps more, it grows just two long leaves, which ...
