@Angilion: The joke? I was making one! I'm just saying that Mother Nature is more amazing than "science" gives her credit for.
At the time the "flexable wings" of various insects wasn`t known. Flex-wings VASTLY improve the lifting power of bug wings, so YES (obviously) bumblebees CAN fly, we just didn`t know EXACTLY how for a while.

It is physically impossible for bumblebees to fly.
No, it isn't. The claim that science shows that bumblebees aren`t able to fly is a combination of lack of understanding, urban myth and people trying to undermine science for religious reasons. It stems from applying equations regarding the flight of aeroplanes to bees. An aeroplane-sized bee moving as slowly as a bee wouldn`t be able to fly, which only proves that bees don`t fly in the same way as aeroplanes. Hardly a surprise.

pterodactyls didnt fly, they glided Katsufumi Sato, a Japanese scientist, did calculations using modern birds and decided that it is impossible for a pterosaur to stay aloft. But in the book 'Posture, Locomotion, and Paleoecology of Pterosaurs` it is theorized that they were able to fly due to the oxygen-rich, dense atmosphere. Denser than what we have today.
However, both Katsufumi and the authors of the above book based their research on the now outdated theories of pterosaurs being seabird-like, and the size limit doesn`t apply to terrestrial pterosaurs.
So, pterodactyls did so fly! Mostly I base this on my desire to believe they did :) Just like in the Flintstones.
