Bearzi is the dolphin biologist and Stanford is the primatologist. The "parallels" among nice apes and dolphins that the authors converse of include often within the use of what we name "intelligence" of their variations to lifestyles. for that reason it is a comparability of dolphin intelligence with primate intelligence, and naturally implicitly with human intelligence.

The sections in the chapters are written first on one species after which at the different in order that dolphin social habit, for instance, could be in comparison with primate social habit (Chapter four) or that their navigation via their differing environments can equally be in comparison as in "Swimming with Dolphins, Swinging with Apes" (Chapter 3).

I was once semi-surprised to benefit that wild bottlenose dolphins even with no arms have still been saw utilizing tools--or a t least one software, a sponge worn as "a nostril cap." the most hypothesis this is that the dolphins use the sponges "to guard themselves from various damaging and poisonous organisms close to the ocean ground and to prevent the abrasive sand, rocks, and damaged shells that muddle the deep waters..." (pp. 144-145).

Of path dolphins in sea exhibits were taught to exploit balls and different gadgets as "tools for entertainment"--which brings me to this attention: is dolphin intelligence restricted by means of the truth that dolphins don't have any arms with which to take advantage of instruments? The authors appear to imagine so, and at any price the sponge use is the one instance of device use within the wild that they document. Which brings up the query of the way a lot will we fairly find out about dolphin habit and intelligence? gazing animals in zoos or as a part of a theatric express is something; looking at animals within the wild is one other. Animals within the wild behave in ways in which could shock us, and our wisdom of the use and quantity of dolphin intelligence could be constrained simply because we aren't capable of systemically stick with them within the wild.

The similar is correct for chimpanzees and different primates. within the February, 2010 factor of "National Geographic" there's a fascinating article by means of Joshua Foer (with photographs by way of Ian Nichols) approximately an come across with chimps within the Congo's Nouabale-Ndoki nationwide Park. in contrast to different areas in Africa the chimps encountered right here had it appears by no means noticeable people prior to. Their behavior--full of interest and "approach/avoidance" monitors together with nesting in a single day within the timber at once above the camp of biologists Dave Morgan and Crickette Sanz--proved so much fantastic. The chimps spent a part of the evening "testing" the people via throwing down urine and feces onto the tents and howling! this can be a bit varied from different studies that i've got read.

In "Beautiful Minds," the authors speculate on no matter if dolphins and apes have "a thought of mind"--that is, whether or not they are conscious of what others might be considering and whether or not they have a feeling of self. a few dolphins have been "marked with black ink in a space in their our bodies no longer obvious to them. they can, even though, consider the ink. A reflect used to be provided, and the dolphins have been watched to determine in the event that they have been visually tracking their our bodies to discover the ink spot." a few have been. (pp. 180-181) this means self-awareness. In chimps it has lengthy been recognized that they realize themselves in mirrors and discover that the picture within the replicate isn't another chimp. the following it really is pronounced that an Asian elephant "was additionally in a position to move the replicate self-recognition try, again and again touching a white X at the part of her head together with her trunk." (p. 180)

What is apparent to me is that the good intelligence verified by means of chimps, bonobos and dolphins (and people, incidentally) is essentially the results of the necessity to comprehend and negotiate the complicated social relationships they've got with others. this can be the major to the expansion of those titanic brains. yet intelligence outlined because the skill to resolve difficulties applies on to the hunt for and procurement of meals. Dolphins use cooperative searching to enclose and strength to the outside colleges of fish in order that they can't simply get away. They even use bubbles to confuse and confine the fish. Apes use their minds to discover and bear in mind the place and once they came across culmination in season in an unlimited forest.

Ape intelligence is outwardly constrained by way of their lack of ability to shape summary innovations, specially when it comes to language that might let them go on info to others. when it comes to dolphins this isn't so transparent when you consider that we're at a loss whilst attempting to comprehend what they're "saying" or why they do a little of the issues they do. it can be that we'll locate that dolphins do certainly have a few experience of the summary and will converse approximately issues resembling fish no longer instantly current or activities and occasions some time past or imagined, that's the essence of human conceptual talents. The trick is to have symbols comparable to phrases to face for anything no longer current or for acts now not in proof. Apes are restricted of their skill to represent. Are dolphins so restricted? we do not but know.

Bearzi and Stanford during this very readable booklet have performed an exceptional activity of bringing to a normal readership a number of the most up-to-date principles and discoveries which are best us towards a better figuring out of those precise beings, and naturally to a greater comprehend of ourselves.

Sample text

The fish were trapped ingeniously, as if in a net shaped by a tight formation of nine dolphins. Just after they began feeding, one of the dolphins in the group suddenly left the circle, swimming offshore at a high speed. In less than an instant, the other dolphins left their prey to follow their companion. This was an odd behavior for my metropolitan dolphins. Usually they moved back and forth very close to the beach, taking the time to entirely deplete the school of fish on which they were dining while occasionally milling at the surface like a bunch of oversized floating buoys.

In less than an instant, the other dolphins left their prey to follow their companion. This was an odd behavior for my metropolitan dolphins. Usually they moved back and forth very close to the beach, taking the time to entirely deplete the school of fish on which they were dining while occasionally milling at the surface like a bunch of oversized floating buoys. To abruptly stop feeding and take off in an unrelated direction was rather peculiar. Always curious, I left the schooling fish, still visible from the surface, and accelerated into the incoming waves to follow the dolphin group.

For these and other reasons, it is perhaps unsurprising that fieldwork at sea lagged behind the study of apes twenty or more years. Although early data on the biology and population of large whales and stock management were collected in the commercial whaling community, the first glimpse of the social lives of small dolphins came from the tanks of marine studios. In the early 1940s, the comparative psychologist Donald Olding Hebb shifted his focus from primates to dolphins, collaborating on one of the first studies of dolphin social behavior in captivity.
