There's an old story that gets tossed around about evolutionary biologist J.B. Haldane on the origin of what would become one of his favorite phrases. Someone asked him what his studies of the natural world had revealed about the nature of "the creator" if one existed.
Well, Haldane replied: If he exists, he has an inordinate fondness for beetles.
And indeed, the world has an awful lot of beetles
. When you ignore bacteria (which are obviously ridiculously diverse), beetles are probably the most diverse kind of life there is. If you stuck your hand into a bag full of one of every plant, fungi, animal and insect species on the planet (ew), you'd probably pull a beetle out.
