“Unexpected aerodynamics of bat flight…it just gets harder for evolutionists”!!
“The stretchy skin on a bat’s wings interacts with air differently compared to the firmer wings of birds and insects. This elasticity, combined with dozens of joints (even more than in a human hand),3 allows bats to generate unusual wing shapes and motions, e.g. that give more lift at higher angles of attack—the angle at which the wing meets the air on the downstroke. This may allow bats to fly at low speeds with less risk of stalling.
LiveScience put it this way: “The complexity of bats’ wings also challenges some current theories that say bats evolved from some kind of flying squirrel-type creature.”
“gliding appears to have evolved seven times in mammals”, but “not a single one of those groups is closely related to bats.””
It looks like there is no solid evidence of the evolution of bats – what’s the alternative??
