Charles Darwin called it an "abominable mystery" and it has perplexed generations of botanists who have tried to explain the sudden and dramatic appearance of flowering plants 130 million years ago.

For tens of millions of years, land plants consisted of mosses, ferns, firs and conifers. But then, the fossil record shows, there was an explosion in a new kind of plant - one with flowers that soon became the most diverse and dominant botanical group.
