Whales and dolphins have rich 'human-like' cultures and societies
After humans, orcas (Orcinus orcas) are the most widely distributed mammals on Keywords: killer whale, dolphin, behavior, social habits, language as well as exceptional memory and communication skills (amongst other. Students investigate people's historic relationship with whales and compare it to Language Arts, Geography, Human Geography, Social Studies, Economics. Human–animal communication is the communication observed between humans and other . Later in the project the dolphin's ability to process linguistic syntax was made apparent, in that it could distinguish . to signal to human whalers that the orcas were herding large baleen whales nearby, so the humans would send .
This communication is two-way, as owners can learn to discern the subtle differences between barks and meows, and there is a clear difference between the bark of an angry dog defending its home and the happy bark of the same animal while playing. Communication often nonverbal is also significant in equestrian activities such as dressage. One scientific study has found that 30 bird species and 29 mammal species share the same pattern of pitch and speed in basic messages, so humans and those 59 species can understand each other when they express "aggression, hostility, appeasement, approachability, submission and fear.
Most bird species have at least six calls which humans can learn to understand, for situations including danger, distress, hunger, and the presence of food. Two birds preferred Bach and Vivaldi over Schoenberg or silence. The other two birds had varying preferences among Bach, Schoenberg, white noise and silence.
The human call varies regionally, so the honeyguide's response is learned in each area, not instincive. Great ape language Chimpanzees can make at least 32 sounds with distinct meanings for humans. The research showed that they understood multiple signals and produced them to communicate with humans. There is some disagreement whether they can re-order them to create distinct meanings. Baboons can learn to recognize an average of 4-letter English words maximum ofthough they were not taught any meanings to associate with the words.
Whales and dolphins have rich cultures – and could hold clues to what makes humans so advanced
In Toronto, for hundreds of songs in random order, orangutans were given one second segment of a song, and then chose between repeating that segment or 30 seconds of silence. There was no pattern of selections by genre, and the researchers did not look for other attributes which were shared by the orangutans' chosen segments.
No comparison was available of how many second segments humans would repeat in the same situation. In another experiment the orangutans did not distinguish between music played in its original order and music sliced into half-second intervals which were played in random order. Chimpanzees can hear higher frequencies than humans; if orangutans can too, and if these overtones are present in the recordings, the overtones would affect their choices.
Lilly sponsored English lessons for one bottlenose dolphin Tursiops truncatus. The house was partially flooded and allowed them to be together for meals, play, language lessons, and sleep. It was able to perform tasks such as retrieval of aurally indicated objects without fail. Department of Anthropology, Smithsonian Institute, Cat.
A In archaeology, such attitudes have limited our understanding of Arctic prehistory, says Erica Hill, a zooarchaeologist with the University of Alaska Southeast. Whaling amulets and bone circles were written off as ritualistic or supernatural with little exploration of what they actually meant to the people who created them.
Instead, archaeologists who studied animal artifacts often focused on the tangible information they revealed about what ancient people ate, how many calories they consumed, and how they survived.
Hill is part of a burgeoning branch of archaeology that uses ethnographic accounts and oral histories to re-examine animal artifacts with fresh eyes—and interpret the past in new, non-Western ways. Yet constricted by Western science and culture, few archaeologists have examined the record of human history with the perspective that animals feel emotions and can express those emotions to humans.
The site was estimated to be 1, to 2, years old, predating the dawn of whaling in the region, and was situated at the top of a large hill. As her team dug through the tundra, they uncovered six or seven intact walrus skulls deliberately arranged in a circle. Like many archaeologists, Hill had been taught that ancient humans in harsh northern climates conserved calories and rarely expended energy doing things with no direct physical benefit.
That people were hauling walrus skulls to a hilltop where there were plenty of similar-sized rocks for building seemed strange. So she started wondering: There was no shortage of examples: To Hill, though, some of the most compelling artifacts came from whaling cultures. Museum collections across North America, for instance, include a dazzling array of objects categorized as whaling amulets. From this grab bag, Hill identified 20 carved wooden objects. Many served as the seats of whaling boats.
One amulet in particular stands out. The artifacts were housed in hundreds of floor-to-ceiling drawers, row after row of them, with little indication of what was inside.
She pulled open one drawer and there it was—the perfect likeness of a bowhead whale staring back at her. The object, likely from the late 19th century, probably functioned as a crosspiece. Itwas hewn from a hunk of driftwood into a crescent shape 21 centimeters long.
A precious bead of obsidian was embedded in the blowhole. The meticulously rendered art was thus meant not for humans, but for whales—to flatter them, Hill says, and call them to the hunters. Yupik stories from St. Lawrence Island tell of whales who might spend an hour swimming directly under an umiak, positioning themselves so they could check out the carvings and the men occupying the boat.
If the umiak was clean, the carvings beautiful, and the men respectful, the whale might reposition itself to be harpooned. Then the whale might swim away. They bathed in special pools, prayed, spoke quietly, and avoided startling movements that might offend whales. The paralimbic lobe is an outgrowth of the areas of the brain that are known to control communication and social emotions in all other mammals, rendering it possible that orcas experience feelings, emotions and social connections such as love, joy and grief on a level that human beings cannot even comprehend.
It is certain that orcas can understand hand signals, symbols on flashcards, and vocal cues when interacting with humans.
They sleep from five to eight hours a day. However, there is a big difference in the ways in which orcas sleep in comparison to humans. The orca shuts down one hemisphere of its brain as well as the opposite eye controlled by that hemisphere, while the other hemisphere and eye remain alert.

This makes them awake and asleep simultaneously. EEG studies with dolphins have helped researchers to determine this kind of sleep. An interesting fact is that orca calves spend the first months of their lives wide awake, with no sleep whatsoever.
One is that this could be a way of staying safe from potentially harmful predators while they are still young; after all, mortality rates are high amongst newborn orcas. The second key reason is that these infants need to keep their bodies warm through constant activity until they grow older and develop blubber.
Resting in such a way also helps the pod members to avoid boats at a time when only half of their brain is awake. They can hear an ample range of sounds, possess admirable vision in and out of the water, and their skin is very sensitive to the touch. When the sound wave hits an object, it bounces back and returns to the orca. Using echolocation, orcas can detect other animals or objects in the area, as well as their size and shape. The clicks emitted through a fatty organ in the forehead called the melon hit objects and bounce back to the orca with important information.
Whistle sounds are produced by the larynx enabling them to create more than one sound at a timesince they do not have vocal cords. The young orca needs about two years of practice to attain a full repertoire of sounds.Communication attempt between Orcas and human
An example is the results obtained from an analysis of Norwegian and Icelandic orca pods: In the wild, it has been recognized that orcas are far more cooperative with humans, as proven in the case of the orcas of Eden, Australia. This finding was documented in the s by whaling overseer Sir Oswald Brierly in his extensive diaries.
The orcas would find target whales, lead them into a bay, and then alert the whalers of their presence in order to help catch them. The leader of the orcas was named Old Tom, and he would be amongst the first to alert the human whalers of the presence of whales by breaching or tail slapping at the mouth of the Kiah River.
