A demanding but fascinating read. Scientific-method focused, so to lay readers such as myself, reading was challenging at times. But allow yourself distraction-free hours and you'll be rewarded with fascinating observations and profound thoughts about culture as it relates to many species, and questions about morality and how humans share more than has been acknowledged with other sentient beings. Many of the differences assumed between species in regard to cognition owe to the difference types of behavior and knowledge required to live in vastly different environments -- contrast land with vast seas. Stick with this book to the end.
My notes:
The Cultural Lives of Whales and Dolphins
Hal Whitehead and Luke Rendell
Approach studies like puzzles.
Heady concepts like mitochondrial evolution, cultural hitchhiking.
Ethology (behavior) and ecology (env)
Culture can drive the population biology of a species evolutionarily, ethologically and ecologically.
Culture, genes, drive, society is group
culture behaviors taught parent, social group
Can be same function - sponge on nose so dolphin not scrape while hunting prey in tight pace, another uses stick
meme - cultural analog of genes, passed on
Song culture food buildings
Animals migrate fly build homes, songs,
Shared sense of morality.
Sometimes personally dangerous cooperative behavior.
Kin selection : us vs. them
Group selection on cultural traits -- some dismiss the idea this occurs within nonhuman animal societies.
Culture allowed humans to dominate the sea tho not marine mammals.
Echolocation, sonar intelligence!
(mysticetes baleen vs. toothed)
Emulation: copy goal of a behavior vs. specific form.
Some dolphins will put sponges on nose in crevices to dig out food, others use sticks to protect their skin. Dolphins with such knowledge are more reproductively successful.
Religions in human culture that legitimize material wealth seem to be attractive, spreading fast at the expense of more austere variants, and religions demanding human sacrifice haven't survived the test of time.
Orca: social, cultural and cognitively complex creatures that have never killed a human in the wild.
Ecotype: diff ways of life, not just feeding.
Different orcas eat diff prey.
Orcs are picky eaters, xenophobic and cultural.
Residents: stay in same pod, clan and community whole life.
Ecotype encompasses several communities.
Variations in behavior and lifestyle = culture.
Variations of behavior caused by genetics, ecology and culture.
LANGUAGE: Close range clicks, whistles, pulse calls distance - dialects too.
Vocalize mainly when not foraging.
Highly synchronized movements in communal foraging.
Seasonal migrations Antarctica to Uruguay, like warmth, clean skin, rejuvenate. Cold = rough skin, systems shut down to conserve energy to endure cold. “Their holiday leaves them in better spirits as well as with more attractive skin!”
Adapt to habitat. When land animals entered oceans, lost many land adaptations. Streamline, big with blubber to float, buoyancy, insulate...survive water, cold water, depths, navigational senses and behaviors .... few refuges underwater from predators.
Temperature regulation.
Babies born larger and able to swim (like horses and calves, rise fast)
Cognitive abilities, bigger brains evolved.
Song of the humpback whale., mate, structure and appeal of the song, volume, size of male, song cycle has 8 themes., at end of each surface to breathe.
Courtship
Super-alliance of whales. Characterized by huge synchrony in movement.
Diversity of foraging.
Ecotypes, groups defined mainly by what eat.
Dolphins learn to take food from fishing lines...to their detriment.
Family units, pods, clans, communities, ecotypes
Vocal clans
Clicks whistle , spermaceti
Dialects
Multilevel societies: humans, elephants, sperm whales, killer whales.
Large-scale cooperation rare outside humans except social insects: ants, bees, termites and the naked mole rat.
Sperm whales nomadic, females intensely communal.
Bottlenose dolphins drafted into US military.
Copy and emulate human behaviors.
Reiss underwater keyboard
learn from other species and in captivity.
Dolphins more body-oriented movements when calves around - teach.
Pointing gestures when humans faced them.
Imitation, emulate behavior
Variability of behavior caused by genetics, ecology and culture.
Culturally complex animals.
Plausible explanation vs. scientifically experimentally proven. Can't be sure of the mechanism of learning, but culturally transmitted obvious when all whales sing the same song in an ocean basin.
Dolphin tail-walking.
Foraging strategies.
Some killer whales beach selves to catch seals, sea lions calves, and improve their hunting skills..cooperative fishing...sperm whale learns how to carefully remove sablefish from longline. Sharks don't.
Observed one raised in isolation. Free Willy star Keiko irony returned to captivity in Mex. Name means lucky blessed, but captured age 2 from Iceland waters. Eventually after move,free Keiko, with Hollywood money, flown back to Iceland to prepare for release. But had trouble interacting with wild whales didn't known dialect, culture. Ignored him. , trouble feeding. Scared returned to tracking boat. Eventually began provisioning hi, died 23 pneumonia.
Some like Springer reintegrate successfully.
Ghost whale own song 1992-2004 betw Alaska and Mexico.
Evolutionary biology
Much whale and dolphin behavior is acquired by social learning, is shared by groups, and therefore is culture.
Respond to environment, heat, cold, so much social learning adaptive.
Frans de Waal
Marine mammals sirenians manatees and dugongs social, mother-calf bond lasts up to 2 years. Sea grasses stabl resource compared to pelagi fish and squid that are the staples of most cetaceans.
Cetaceans don't make hand axes, or anything else that endures, so how can we chart the development of cetacean culture? Pieces of evidence include development of our brains. Large brains are a feature of the most culturally sophisticated species, and the human brain increased substantially in size just about when the axes grew complex and diverse.
Lori Marino neuroanatomist: echolocation came online, kickstarted social learning and brain expansion. Cognition.
Energy spent getting prey.
Culture changes everything. When significant amounts of information begin flowing within species independently of their DNA, evolutionary processes can be affected in profound ways.
Gene-culture coevolution
Killer whales illustrate 4 ways distinct behavior developed: xenophobia inhibiting mating between ecotypes, diff ways to obtain food (Keiko failed to make social connections when released from captivity), gene evolution....
Menopausal members' function to help teach, especially behaviors in response to El Nino-type climate events that they are old enough to remember and had survived.
British Cavalry vs Russia, knew mission was suicidal during 1854 Crimean War... Alfred, Lord Tennyson poem: charge of the light brigade: Theirs not to reason why, Theirs but to do or die. Cultural imperative.
Culture can reduce numbers in these slow-reproducing animals when they stay in territories like Puget Sound that are noisy, polluted, human urban waterways.
Incentive to be bold and take fishing line fish.
Commercial whaling extirpated individual whales and fractured habitat and societies, study of 11 subspecies of baleen whales never recovered.
Some cetacean culture, like the humpback, bowhead and blue whale songs or the call traditions of killer whales, is clear. Much, including the variation in behavior among the units, pods, and clans of the matrilineal whales is very compelling. Features of animals with important cultures: large brains, prolonged mother-infant dependency, menopause, maladaptive (stupid) behavior, ecological success, wide habitat ranges, large-scale cooperation and indications of the coevolution of genes and culture.
Disease outbreak affected forest baboons removed the more aggressive members and the difference, had through social transmission, changed the culture to a pacific culture...no significant difference in hormone levels in their blood between lowest- and highest-ranking males, and more grooming from females for new males joining the group than in control groups.
Chimps playing by waterfall, observed by Jane Goodall: display behaviors, dance, seems to be shared activity.
Is carrying around dead infant by chimps, elephants and cetaceans a misdirection of maternal care, or something more?
Last chapter - wow!
Read it!
The rest of the book builds a case for consideration of nonhuman animals with cognitive and cultural traits.
Birdsongs structured, as are humpback whales, used in courtship and mating, vary geographically and evolve over time. The songs of baleen whales and songbirds can be complex or simple (fin whales and bullfinches). If sped up, maybe 16 times or about 4 octaves, humpback whale song sounds quite a lot like birdsong.
Whales are huge, so sing loud, and their songs travel far in water.
Birds learn much from each other -- horizontal learning (peers… vertical parent to child). Migration, feeding and breeding habitats, choice of decorations and courtship bowers of bowerbirds, recognize and warn of predators, dangers...alarm calls, feeling activities.
Avian social learning case: tits opening foil or cardboard caps of milk bottles and drinking the milk when delivery spread across Britain between the 1920s and 50s.
New Caledonian crows make leaves into elaborate tools to extract insects from cavities -- socially learned.
Chimps - we study and have learned so much about them because: they are our closest evolutionary relatives...primatologists have worked out ways to observe wild chimps consistently - researchers habituate group so they ignore human presence and then observe over time...their behaviors seem similar to ours...unlike other “cultural species,” chimps are not nocturnal or aquatic and habitat for many rather accessible. Bonobo (pygmy chimp) though similarly related to humans, live in less accessible habitat. And chimps display lots of culture.
Yet cetaceans appear to be superior social learners compared to primates, especially in the vocal domain. So in vocalizing, more similar to humans. Chimp societies are not multicultural anywhere near to the degree as those of killer and sperm whales.
Gay Bradshaw in her book “Elephants on the Edge: What Animals Teach us About Humanity” contends complex vast elephant culture.
Elephants maintain large stores of knowledge about their social and physical world and they can learn from each other their vocalizations, what to eat, and more. Data sets collected in the Amboseli National Park in Kenya (Cynthia Moss, Joyce Poole observations...reviewed by Lucy Bates and Dick Byrne)-- demonstrate how elephants keep a mental map of the whereabouts of family group members when when they are out of sight.
Elephants can identify, and react appropriately to, both the typical scent and typical garment color of young Maasai men, who have a cultural practice of demonstrating virility by spearing elephants, in comparison to similar cues from the much less dangerous Kamba tribe, who have a more agricultural culture. The elephant can not only distinguish between the tribes but also between dangerous and benign members of the tribes - young males and females, respectively - solely by listening to recordings of their voices. Also simulated estrus -- thought to teach young female kin how to handle themselves in adult society...pick the right male.
The value of the information held by older individuals is indicated by the responses of elephant groups to a prolonged drought in Tsavo National Park, Tanzania, in 1993 Calves were much more likely to survive if their groups left the park during the drought, and they were much more likely to leave the park if their clan contained females old enough to have experienced the preceding severe drought in 1958-61.
Culture includes songs, foraging methods, movement, play, mating, parenting.
Language:
Dolphins and whales communication mainly acoustically.
The key attribute of human language is syntax. Syntax allows a finite number of words, together with a few rules, to express an infinite number of concepts.
Dolphins and other animals including bonobos and African gray parrots, can learn and use some syntax when taught by humans. They can distinguish between “bring the ball to the hoo” and “bring the hoop to the ball.” Dolphins appear to use signature whistles as quite specific labels to refer to individuals.
But to our knowledge, wild whales and dolphins do not use syntax, or in a simple way. Click patterns.
Thus whales, dolphins, apes, monkeys, and birds do not have the long narrative stories, lectures about the structure of their worlds, or sets of instructions for doing or making complicated things that our language gives us. (Oral histories.)
Not having language is not necessarily a cognitive deficit especially since dolphins can use syntax when trained by humans.
But they vocalize/communicate. And they can point to things and use sounds to refer to one another. They communicate frequently and enthusiastically.
Morality
Human infants in some studies begin making judgments about the behavior of others before than can talk.
When killer whales washing seals off ice floe...one seal swam frantically toward the numpbacks...one humpback rolled over back, swept seal between massive fippers on his/her chest, then as killer whales approached, the humpback arched chest, lift seal out of water and nudged with flipper back to middle of its chest, then seal scrambled off and swam to safety of nearby ice floe..
2998 Moko bottlenose dolphin guided mother calf pair of pygmy sperm whales out of an intricate set of sandbars off the coast of New Zealand where they seemed disoriented and trapped -- rescue workers were considering euthanasia after the pair stranded 4 times.
Appear to be altruistic moral acts.
When a human protect another, we call it compassion. If a humpback whale does so, why call it instinct?
When considering the moral standards of human culture, it seems churlish to deny the cetaceans made conscious decisions to save the other animals. We cannot know the motivations of the animals, but then again, how can we know it for sure of our fellow humans?
Dolphins helping humans in peril. Sperm whales clearly control the strength of their powerful sonar ofr else could permanently damage others at close range, thus suggests learn and share agreements about the right thing to do.
The final key attribute of human culture affects biological fitness - reproductive success, affects genetic evolution.
Shark Bay, Australia study: calves of provisioned dolphins who came to the Monkey Mia resort beach for handouts from humans had over twice the probability of dying in their first year compared to those of nonprovisioned females. Connection between reproductive success and the famous cultural trait of the Shark Bay dolphins, sponging. Females who put sponges on their noses raised calves at higher rates than average dolphin.
Only in the sponging of the bottlenose dolphins is there even potential evidence of material culture, whereas we are physically surrounded by our material culture, and it accumulates spectacularly.
There is a similar contrast with syntactical language. But here are indicators of morality and that it affects biological fitness.
SHould whale and dolphin culture influence how humans treat them?
Does culture have moral worth?
But then, when asking Japan to abandon their whale hunting has prompted the defense: like asking Australians and Americans to stop eating meat.
Humans separate life forms in personal and nonpersons, considering needs and vulnerabilities. But arguments about assigning personhood to brain-dead but physiologically living individuals and fetuses lacking aware and sensations.
Personhood in humans defined as including factors such as being alive, being aware, having positive and negative sensations, emotions, and a sense of self; controlling one’s own behavior, recognizing other “persons” individually and treating them appropriately; and possessing a variety of sophisticated cognitive abilities. Bottlenose dolphins meet these requirements and thus has “moral standing,” says philosopher Thomas White.
Culture could be regarded as a necessary ingredient of personhood, informing moral debates.
