This highly complex mode of wing folding is one of the many examples of engineering marvels in insects that strongly suggest intelligent design.
Outside of Darwinian fantasy land, we lack any transitional fossils to document an assumed gradual evolutionary development of characteristic pterosaur wings.
Scientists are only humans and many of them see what they want to see. Fossils often leave a lot of room for wild imagination and wishful thinking.
Ubiquitous discontinuities contradict the gradualist predictions of Darwin’s theory and thus should count as empirical falsifications of that theory.
Perhaps this organism had four legs. Perhaps it had flippers. Perhaps it was closely related to whales. Perhaps it has nothing to do with whales.
