The Cute, the Cuddly, and the Colossal

nine-banded armadillo

Contemporary psychologists have been able to figure out why human beings are drawn affectionately to certain animals.  The secret lies primarily in our emotions being easily captured by the round, big-eyed face of a baby, an instinct that has helped the human race protect its fragile offspring and thus endure.  This instinct is also revealed in our hearts' being easily tugged by paintings of big-eyed children, and by dogs bred to look more baby-faced.  That human instinct cannot explain, however, the seeming proclivity of Texans and other southerners to find armadillos cute. Those animals, with their long pointed noises and tiny eyes, have heads the very opposite of human babies.  There is a bit of a mystery here.  Behind armadillos also lies a story about how Darwin unraveled what was once called the "mystery of mysteries."  Namely, how new species evolve.

When Charles Darwin was on his groundbreaking trip on the Beagle around South America, he stopped many times to travel inland, studying the life-forms in that foreign land.  Darwin had a keen scientific eye for the similarities and dissimilarities between various species, both living and extinct.  Scientists at that time had been trying to piece together the puzzle of the fossil remains of some colossal species that no longer existed.  Darwin found the fossilized armor-plate of an extinct nine-foot cousin of today's armadillos (which in the U.S. are about one-and-a-half feet long).

Even though most of us today might be repulsed by the idea of eating an armadillo (either because of its possible taste or its cuteness), Darwin and his companions dined on a species of armadillo.  The preparation of that meal would have helped Darwin see the similarities and dissimilarities between the armor-like coverings of existing and extinct species of armadillos.  As he explained later in his autobiographical reflections:  "During the voyage of the Beagle I had been deeply impressed by discovering in the Pampean formation great fossil animals covered with armour like that on the existing armadillos...."

The relationships between the complex skeletons of existing and colossal extinct species (such as sloths) was challenging even to scientists.  Here is where the simpler armor of armadillos was something Darwin could take advantage of in Origin of Species, writing that a "relationship is manifest, even to the uneducated eye, in the gigantic pieces of armour like those of the [extinct] armadillo found in several parts of la Plata."

Now that Darwin and evolutionary biologists have done so much work on the background of these creatures, we are left with trying to understand ourselves:  Why are people so easily fascinated by armadillos, even finding them cute?  With their hard covering, they do not fit into the category of "soft, cute, and cuddly," which would latch in with our mammalian tactile affection.  Some of our delight in armadillos seems to come from their very oddness.  Also, when one is spotted in the wild, there can be the excitement and fun of trying to chase the small animal as it scurries in the underbrush.  We are just lucky those colossal nine- footers are no longer around!

Have you ever seen an armadillo or other peculiar-looking animal in the wild?  When?
