When a Brazilian free-tailed bat breaks all records by flying at 160 kilometres an hour (100 m.p.h.), there might be more to the story than simply saying that bats are “well adapted to their aerial lifestyle, with long, angular, narrow wings,” as New Scientist puts it.
Of course they are. But such agility is best explained by design.
All creatures that fly are amazing testimonies of creation. A Darwinian trial-and-error approach could hardly produce amazingly effective fliers.
Gary McCracken of the University of Tennessee in Knoxville and his colleagues “used an airplane tracking device on seven bats from the Frio Bat Cave in south-western Texas to track ground distance covered by bats.”
While they cannot be absolutely sure whether tailwinds or gravity might have helped the bats to beat records, they believe that the wind was weak during the night they measured their speeds.
Other flying creatures have amazing abilities, as well.
