Recent advances in molecular phylogenetics and a series of important palaeobotanical discoveries have revolutionized our understanding of angiosperm diversification. Yet, the origin and early ...
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 ...
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 ...
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 ...
Figure 1: Hypothetical tree topologies and summary of orthogroups consistent with ancient gene duplications before the split of monocots and eudicots. In summary, our conservative filtering procedure ...
Incompatibility is a common means of controlling breeding behaviour among plants, and has been an important factor in evolution. It acts to prevent self-fertilization, as well as to prevent ...
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 ...
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 ...
