Marino and co-author Christina Colvin, also from Emory, came to that conclusion after reviewing dozens of studies conducted on pigs and other animals. "There is good scientific evidence to suggest we need to rethink our overall relationship to them." "We have shown that pigs share a number of cognitive capacities with other highly intelligent species such as dogs, chimpanzees, elephants, dolphins, and even humans," neuroscientist Lori Marino of Emory University and The Nonhuman Rights Project said in a press release. The research project, described in a paper published in the International Journal of Comparative Psychology, aims to put a face on animals that are traditionally just viewed as sources of meat. Pigs can often outsmart dogs and are on about the same intellectual level as our closest living relatives, chimpanzees, according to a new paper.
