A Look At How Animals Think


Economist: Animals think, therefore…

The inner lives of animals are hard to study. But there is evidence that they may be a lot richer than science once thought

IN 1992, at Tangalooma, off the coast of Queensland, people began to throw fish into the water for the local wild dolphins to eat. In 1998, the dolphins began to feed the humans, throwing fish up onto the jetty for them. The humans thought they were having a bit of fun feeding the animals. What, if anything, did the dolphins think?

Charles Darwin thought the mental capacities of animals and people differed only in degree, not kind—a natural conclusion to reach when armed with the radical new belief that the one evolved from the other. His last great book, “The Expression of Emotions in Man and Animals”, examined joy, love and grief in birds, domestic animals and primates as well as in various human races. But Darwin’s attitude to animals—easily shared by people in everyday contact with dogs, horses, even mice—ran contrary to a long tradition in European thought which held that animals had no minds at all. This way of thinking stemmed from the argument of RenĂ© Descartes, a great 17th-century philosopher, that people were creatures of reason, linked to the mind of God, while animals were merely machines made of flesh—living robots which, in the words of Nicolas Malebranche, one of his followers, “eat without pleasure, cry without pain, grow without knowing it: they desire nothing, fear nothing, know nothing.”

Why Do Zebras Have Stripes?


Why Do Zebras Have Stripes? Scientists Have The Answer -- The Guardian

There have been many explanations for the zebra’s impressive stripes. New research strongly suggests that they have evolved to deter parasitic flies.

The zebra’s striped coat is simultaneously extraordinary and stunning. So wondrous, in fact, that many people have imagined it to be evidence of God’s infinitely artistic hand. Over the years, there have been many more rational explanations, but that all-important scientific consensus has remained elusive.

Charles Darwin certainly found the zebra’s stripes to be a conundrum. In The Descent of Man, he dismissed the idea they could act as camouflage, citing William Burchell’s observations of a herd:

My Comments: It apparently all comes down to biting flies not liking stripes.

Why Wolves Cannot Be Tamed

Why Dogs Can Be Tamed But Wolves Cannot -- Science 2.0 

Wolves and dogs are genetically very similar, so why did dogs become "man's best friend" while wolves remain wild? Kathryn Lord at the University of Massachusetts Amherst suggests the different behaviors are related to the animals' earliest sensory experiences and the critical period of socialization.

Not much is known about sensory development in wolf pups and assumptions are usually extrapolated from what is known for dogs - but there are significant differences in early development between wolf and dog pups, chief among them timing of the ability to walk.

My Comment: Bottom line .... wolves are tricky animals to have as a pet.

How Stem Cell Test-Tube Techniques Will Save The Northern White Rhinos

Tragic: Northern white rhinos are extinct in the wild. This photo, taken in 2000, is of a young male with his mother Najin at a Zoo in the East Bohemian town of Dvur Kralove

Northern White Rhinos Set For Stem Cell Test-Tube Babies To Save Species From Extinction -- Daily Mail

The northern white rhino, one of the planet’s most endangered animals, could be saved by pioneering stem cell research.

Scientists at the Scripps Research Institute in La Jolla, California, also hope their work will save other animals teetering on the edge of extinction.

The team have managed to create stem cells from the majestic animals and hope they will eventually be able to produce ‘test tube babies’, too.

Standing At 11 Feet: World's Largest Known Bear Unearthed -- Live Science

The fossils of the largest known bear to have ever lived have been found, a giant that was the most powerful land carnivore of its time, scientists said.

The remains were unearthed during the construction of a hospital in La Plata City, Argentina. It was a South American giant short-faced bear (Arctotherium angustidens), the earliest and largest member of its genus (its group of species of bears). This titan lived between 2 million to 500,000 years ago, with its closest living relative being the spectacled bear (Tremarctos ornatus) of South America.

Top 10 Working Animals


From Live Science:

On Labor Day, we celebrate the accomplishments and contributions of American workers. But humans aren't the only ones who toil: Animals do, too. People have used animal labor for thousands of years, and even today, our fuzzy (or feathery, or slippery) friends can go places and do things we can't.

Do Animals Commit Suicide? A Scientific Debate


From Time Magazine:

Forty years ago, Richard O'Barry watched Kathy, a dolphin in the 1960s television show Flipper, kill herself. Or so he says. She looked him in the eye, sank to the bottom of a steel tank and stopped breathing. The moment transformed the dolphin trainer into an animal-rights activist for life, and his role in The Cove, the Oscar-winning documentary about the dolphin-meat business in a small town in Japan, has transformed him into a celebrity.

"The suicide was what turned me around," says O'Barry. "The [animal entertainment] industry doesn't want people to think dolphins are capable of suicide, but these are self-aware creatures with a brain larger than a human brain. If life becomes so unbearable, they just don't take the next breath. It's suicide."

Feeling Animals' Pain

From New Scientist:

Jonathan Balcombe believes that we have allowed intelligence to become the measure with which we determine how well to treat animals when what we should be using is how they feel.

It is not a new idea - the philosopher Jeremy Bentham said in 1789 that how an animal ought to be treated should be dependent on its capacity to suffer. It is a question that has recently been overlooked by biologists, who are instead determined to prove that some species have cognitive capacities akin to our own.

Anybody Home? The Search For Animal Consciousness


From US News And World Report:

One afternoon while participating in studies in a University of Oxford lab, Abel snatched a hook away from Betty, leaving her without a tool to complete a task. Spying a piece of straight wire nearby, she picked it up, bent one end into a hook and used it to finish the job. Nothing about this story was remarkable, except for the fact that Betty was a New Caledonian crow.

Prairie Dogs Most 'Chatty'

Prairie dogs are highly social and live in large colonies that can span hundreds of acres of the grasslands of North America Photo: ALAMY

From The Telegraph:

On first appearances they seem to be little more than a kind of nervous ground squirrel with a loud squeak, but new research is revealing that prairie dogs are in fact some of nature's most talkative creatures.

Biologists studying the burrowing rodents have found that they have one of the most sophisticated languages in the animal kingdom – second only to humans.

The findings have surprised many wildlife experts as it was assumed that mankind's closest relatives, primates, or intelligent mammals such as dolphins were likely to be the most talkative species after humans.

Did Gorillas Teach Humans The Basics Of Fair Play On The Sporting Field?

Good sports: Apes advance the concept of fair play by helping to keep games going and giving younger competitors the advantage

From The Daily Mail:

Gorillas play competitive games just like humans, although they are more likely to also be good sports, say scientists.

Apes advance the concept of fair play by helping to keep games going and giving younger competitors the advantage, psychologists at the University of St Andrews claim.

Their study has helped trace the evolutionary origins of how humans understand each other.

Mammals 'Floated To Madagascar'

From the BBC:

The ancestors of the current mammals found on the island of Madagascar could have been transported on floating vegetation from Africa, a study says.

Researchers modelled ancient ocean currents and found that favourable conditions existed in the same period as when mammals arrived on the island.

The idea of "rafting" first emerged in 1940, but some argued that a "land bridge" allowed animals to walk there.

Fire Holds No Fears For Chimps, Says Scientist

Observations of chimpanzees could shed light on when our human ancestors first controlled fire. Andrew Aiken / Rex Features

From The Independent:

But did the early ancestor of Man learn how to control it?

Wild chimpanzees have been observed carrying out a “fire dance” in front of grassland wildfires as part of a suite of unusual behaviours that could indicate an ability of man’s closet living relative to understand and even control fire.

Instead of fleeing the wildfires in panic, the chimps were seen to monitor them carefully, showing no signs of the fear that other animals normally exhibit. Their leader – the alpha male – was even observed performing a ritualistic display while facing the flames.

Wolves Aren’t Making It Easy for Idaho Hunters

Marv Hagedorn, an Idaho state representative and hunter, hunting for wolves in the Boise Mountains with his son, John, ahead. Paul Hosefros for The New York Times

From The New York Times:

BOISE NATIONAL FOREST, Idaho — Hunting and killing are not the same thing. Even as Idaho has sold more than 14,000 wolf-hunting permits, the first 10 days of the first legal wolf hunt here in decades have yielded only three reported legal kills.

Such modest early results might seem surprising in a state that has tried for years to persuade the federal government to let it reduce the wolf population through hunting.

Idahoans, among the nation’s most passionate hunters, are learning that the wolf’s small numbers — about 850 were counted in the state at the end of last year — make it at once more vulnerable and more elusive.

Hard Labor: How 10 Animals Struggle to Survive


From Live Science:

Many Americans think of Labor Day as merely the end of summer and part of a welcome three-day weekend. Its origin, however, is in celebrating the labor movement and workers' rights. So enjoy the break (if you get one in this modern 24/7 world), but if you think you have it tough, consider the hard labor put in by these 10 creatures, all just to survive. The list is courtesy the National Wildlife Federation.
