Darwin’s theory left polyploidy a mystery

Article reads: “Ever since Charles Darwin so famously called the rapid diversification of flowering plants in the fossil record an ‘abominable mystery,’ generations of scientists have worked to solve this puzzle,” dePamphilis said. “We used to say that most of the hundreds of thousands of successful species of flowering plants show genetic traces of ancient polyploidy events. The further we push back the date of when these events happened, the more confidently we can claim that, not most, but all flowering plants are the result of large-scale duplications of the genome. It’s possible that the important polyploidy events we’ve identified were the equivalent of two ‘big bangs’ for flowering plants.”
