" Many textbooks point out that no animal has evolved wheels and cite the fact as an example of how evolution is often incapable of finding the optimal solution to an engineering problem. But it is not a good example at all. Even if nature could have evolved a moose on wheels, it surely would have opted not to. Wheels are good only in a world with roads and rails. They bog down in any terrain that is soft, slippery, steep, or uneven. Legs are better. Wheels have to roll along an unbroken supporting ridge, but legs can be placed on a series of separate footholds, an extreme example being a ladder. Legs can also be placed to minimize lurching and to step over obstacles. Even today, when it seems as if the world has become a parking lot, only about half of the earth's land is accessible to vehicles with wheels or tracks, but most of the earth's land is accessible to vehicles with feet: animals, the vehicles designed by natural selection.

" Big Brown Moose
I'm a big brown moose,
I'm a rascally moose,
I'm a moose with a tough, shaggy hide;
and I kick and I prance
in a long-legged dance
with my moose-mama close by my side.
I shrug off the cold
and I sneeze at the wind
and I swivel my ears in the snow;
and I tramp and I tromp
over forest and swamp,
'cause there's nowhere a moose cannot go.
I'm a big brown moose,
I'm a ravenous moose
as I hunt for the willow and yew;
with a snort and a crunch,
I rip off each bunch,
and I chew and I chew and I chew.
When together we slump
in a comfortable clump --
my mountainous mama and I --
I give her a nuzzle
of velvety muzzle.
Our frosty breath drifts to the sky.
I'm a big brown moose,
I'm a slumberous moose,
I'm a moose with a warm, snuggly hide;
and I bask in the moon
as the coyotes croon,
with my moose-mama close by my side. "
