b'Before everything could come up roses, there had to be a primordial flower \\u2013 the mother, and father, of all flowers. Now scientists are on the hunt for it. The eFlower project aims to explain the sudden appearance of flowering plants in the fossil record, what Darwin called an \\u201cabominable mystery.\\u201d\\nMeanwhile, ancient flowers encased in amber or preserved in tar are providing clues about how ecosystems might respond to changing climates.
