		<description>Biologist&#039;s often chalk up questions about why nature does not cover a particular innovation to historical limitations.  They seem to say that other factors would either eliminate a particular permutation, very early on, or, for another different set of reasons, not allow it to pass on genes for perhaps pragmatic reasons.  Wings in nature seem to have covered many of the possible strategies, from humming birds to underwater fliers, and the Burgess Shale seems to have lots of critters who no doubt had unique propulsion systems.  But the most successful and most abundant critters of all are certainly the masters of flight of the insect world.  Soon, they will have it all to themselves.</description>

		<description>Nature has a rotating wing in the form of the Maple Key or Sycamore Seed and what&#039;s interesting about that is that if a Maple Key is overlaid on a Fly&#039;s wing  they are fundamentally the same in profile and in design.</description>

		<description>The bacterial flagellum and its rotary propulsion comes to mind (although it&#039;s obviously not used for flight). http://www.nature.com/nrmicro/journal/v4/n10/box/nrmicro1493_BX1.html

I hope they continue pursuing rotary flight, it may someday enable human flight...</description>

		<description>Amphiox, I wondered the same thing.  However, to exploit your logic, think about the analogous wheel vs. walking.  Nature never created a wheeled animal, but obviously a wheeled robot (Roomba) is much easier to control than a walking one (Asimo).
Nature doesn&#039;t seem to go for easier to control - I would think energy conservation would be the guiding principle.  As such, a FW is much more efficient (I think?) than a RW.  But the trade off in control scheme for a mechanical FW is a tough hurdle.</description>

		<description>Amphiox. It&#039;s called an axle. Hard to make of flesh. Especially, because it has to be a useful apendenge for millions of years before it becomes more and more rotar like.

Plus, the very system of muscles would be different. Perhaps you could have the standard muscle contraction that would give it, the independent axis of the rotary blade, a push along the side, but I don&#039;t see it being efficient.</description>

		<description>It is interesting, I think, to speculate as to why there are no rotary wing organisms in nature. Four times, powered flight evolved independently and all four times flapping wing systems evolved. If RW aircraft are easier to control than FW aircraft, then why wasn&#039;t this advantage ever exploited in nature? What were the contingencies that prevented the evolution of rotating wings?</description>
