Pigs are highly intelligent creatures, ranking fourth in the animal world, behind only chimpanzees, dolphins, and elephants. My favorite bit of pig info from a quick Internet search:
“Last week (2009), an international team of biologists released the first draft sequence of the pig genome, the complete set of genetic instructions for making the ruddy-furred Duroc breed of Sus scrofa. Even on a cursory glance, “the pig genome compares favorably with the human genome,” said Lawrence Schook of the University of Illinois at Urbana-Champaign, one of the team leaders. “Very large sections are maintained in complete pieces,” he said, barely changed in the 100-million-plus years since the ancestors of hogs and humans diverged.” NY TIMES (11/9/2009)
Whatever that means.
This little gal quickly darted back into her shelter on my very first approach, but lingered outside when I returned a short time later.
