Evolution

Monocots type a monophyletic group, definition that castle share a usual evolutionary history. That is widely thought that the monocots were derived from primitive eudicots. Given that the various physical features of monocots are regarded as derived characteristics within the angiosperms, any kind of plant much more primitive 보다 the monocots in these several respects would certainly be a eudicot. Several of the earliest recognized monocot fossils room pollen grains dating to the Aptian age of the beforehand Cretaceous date (125 million–113 million year ago). Molecule clock studies (which employ differences in DNA come estimate once a group break-up from its ancestors) suggest that monocots may have originated as early on as 140 million year ago.
