In her January Scientific American piece titled "What Animals Know most Where Babies Come From," anthropologist Holly Dunsworth makes a convincing case that despite popular assumptions to the opposite, animals generally — and our closest living relatives, the great apes, specifically — don't empathize that sexual intercourse produces babies.
Dunsworth leads off with an example (something I also wrote about here at 13.7) in which the captive gorilla Koko, who knows some American Sign Language and comprehends some spoken English, is asked to brand choices amid several options presented verbally and in diagram class related to "family planning." Dunsworth dismisses the suggestion that Koko is cognitively equipped to understand the four dissimilar scenarios by which she could potentially go a female parent — and I couldn't hold more.
I likewise recall Dunsworth is spot on when she argues that "reproductive consciousness" is unique to our ain species. Just outside the realm of strange anthropomorphic assumptions fabricated by caretakers of media-star apes, exercise people really become effectually thinking that wild animals, farm animals or their domestic dog and cat companions grasp where babies come from? I don't know of bear witness ane way or the other.
People do often assume that animals' behavioral choices are highly cognitive and strategic when they may simply be products of natural selection — and this is part of Dunsworth'south main signal. When a gorilla silverback male person, for case, takes over a new group of females and offspring from a resident rival male person, he may commit infanticide; at the bespeak when a female'due south young infant dies, lactation hormones no longer suppress ovulation and she comes back into estrus, thus becoming a probable mate for the conquering male.
"We love to narrate observations of animal sex activity and parenting with language that implies common ground betwixt them and u.s.," Dunsworth writes. Merely, "animals may carry out all kinds of seemingly complex behaviors without actually anticipating the outcomes."
This lesson is one I brought into my anthropology and animate being beliefs classrooms over and over once again. Students would write or say something like, "Gorilla males kill infants to make females mate with them," as if the whole thing were masterminded in just the same fashion that Kevin Spacey as Frank Underwood plots his next move in the political drama Business firm of Cards. If gorilla males who comport out this strategy have comparatively greater reproductive success than males who don't, that may be enough for the strategy to exist maintained beyond the generations: There need be no cognitive underpinning at all.
Dunsworth goes farther, though, in suggesting there's no show for any abstruse thinking in smashing apes. "Although animals such as chimpanzees are far cleverer than scientists accept traditionally acknowledged," she asserts, "they practise non appear to have this detail cognitive skill." She defines abstract reasoning as "the ability to mentally form representations of unseen underlying causes or forces."
Well, this is an excellent question to with which to kick off a new year. Do animals really non call up abstractly?
I asked Dunsworth, by electronic mail, about evidence — published past researcher Dan Hanus and colleagues at the Max Planck Found for Evolutionary Anthropology in Frg — that some chimpanzees spit water into a vertical tube to raise a floating peanut to within their reach? That human activity fits with Dunsworth's definition. Or, broadening the definition in reasonable means, what nigh fieldwork by primatologists Robert Seyfarth and Dorothy Cheney at the Academy of Pennsylvania that suggests wild vervet monkeys use abstruse concepts when they classify social relationships into types?
Dunsworth replied to my question this fashion:
"I am convinced that the category 'abstract reasoning' is a difficult 1, sort of like the 'theory of mind' category, since information technology'due south possible there'south a level, caste, or kind of information technology that's present in other animals simply unlike from how humans call back. That is, it's hard to abstractly reason about a grade of abstract reasoning unlike our ain. I don't think that innovation — like with the chimpanzees and the floating peanuts, and like the myriad examples in crows — necessarily requires abstract reasoning. In fact, I recollect much of our own behavior that we believe is due to abstract reasoning is actually the same mechanistic, conditioned, plastic, and innovative behavior that'south occurring in other species. That is, non only do we anthropomorphize gorillas and other animals besides much, but we anthropomorphize humans too much.
Caution is always warranted in teasing autonomously these cognitive questions, even so in that location's disarming evidence that some animals reason abstractly under some circumstances (some other examples regarding nonhuman primates tin be found hither; data are available, too, for animals as diverse as dolphins and pigs).
Sharing thoughts, questions, hypotheses and data back and forth like this is, of course, highly valuable, especially when scientists don't fully agree; it'south part of the way science moves forrard. Whereas Dunsworth worries near excessive anthropomorphism, I worry more about our long history of underappreciating animals' cognitive abilities. Animals don't know where babies come from, but they know a great deal more than we once suspected.
Barbara J. King, an anthropology professor at the College of William and Mary, often writes about man evolution, primate behavior and the knowledge and emotion of animals. Barbara'south most recent book on animals is titled How Animals Grieve. You tin can keep up with what she is thinking on Twitter: @bjkingape
