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 ...

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 ...

Most of our food is from angiosperms, while more than 90% of angiosperms require insect pollination - making this pollination method hugely important. Nevertheless, scientists have long been unclear ...

Scientists still strain to make sense of angiosperms' widespread success, which Darwin called an “abominable mystery.” In the last years of his life, Charles Darwin was tormented by an apparent ...
