Dogs in the study were also slightly better-attuned to human voices than people were to those of dogs. That said, what the two species share appears to outweigh the differences, and raise some fascinating questions. Dog intelligence and social awareness is sometimes attributed to the 15,000 or so years they —. Canis lupus familiaris, to be precise — have spent in the company of humans, being evolutionarily rewarded for social sensitivity. The regions tagged in the new study, however, have deep evolutionary roots. Though dogs might conceivably have developed them independently of humans, its far more likely that they were present in that long-ago common ancestor, said Andics. They might even be traced further back into our evolutionary heritage. Anatomy of a human (above) and dog brain, with areas linked to vocal processing outlined.

As expected, human voice-processing areas responded most to human voices. In dogs, corresponding brain regions responded to the sounds of dogs. In both species, the activity in these regions changed in similar ways in response to the emotional tone of a vocalization — whining versus playful barking in dogs, for instance, or crying versus laughing human voices. To people who know dogs as companions and friends, the results might seem predictable. But seeing it play out in the brain drives the point home. Its not a surprising finding, but its an important finding, said cognitive ethologist and author Marc bekoff, who was not involved in the study. Processing vocal sounds and emotion is fundamental to who they are. The responses were not identical between species. In dogs, vocal processing areas also responded to non-vocal sounds, but in humans they were triggered by voice alone — hinting, perhaps, at the intensely social trajectory of human evolution, said Andics. The areas may have evolved to be even more finely tuned for vocal sounds in humans, buy he speculated.
'It's not only dogs and humans. We probably share this function with many other mammals.'. Humans and dogs last shared a common ancestor 100 million years ago. If a voice-attuned region could be found in dogs too, the trait would truly run deep in our shared biology. To investigate the possibility, andics and colleagues trained six golden retrievers and five border collies to lie motionless inside a scanner so the researchers could collect fmri scans of their brains. These scans measure changes in blood flow, which is widely considered an indicator golf of neural activity. Inside the scanner, each of the 11 dogs, and a comparison group of 22 men and women, listened to nearly 200 recordings of dog and human sounds: whining and crying, laughing and barking.
These systems have not previously been described in real dogs or any non-primate species, and the new findings offer an intriguing neurobiological glimpse into the richness of our particular corner of the animal kingdom. What makes us really excited now is that weve discovered these voice areas in the dog brain, said comparative ethologist Attila Andics of Hungarys Eötvös Loránd University, lead author resumes of the feb. Current biology paper describing the experiments. Its not only dogs and humans. We probably share this function with many other mammals. Conducted in the laboratory of fellow Eötvös Loránd ethologist Ádám miklósi, one of the worlds foremost researchers on canine intelligence and behavior, the study was inspired by a turn-of-the-millennium discovery of regions of the human brain attuned to human voices. Similar regions have since been described in monkeys, which last shared a common ancestor with humans 30 million years ago.
Pigeons can do something that humans must develop in a couple of years: they are among the few animals that recognize themselves in a mirror. This self-awareness is an important test to distinguish intelligent animals from those that act instinctively. Fishing, new Caledonian crows seem to have the ability to invent tools. In 2002, the journal Science reported on a crow that bent a wire until it was hooked to take fish out of a container. Control animals, the ants are able to control the lice in farm plants and force them to harvest a sweet nectar they secrete. To make sure they do what their masters want, the ants produce a chemical with which they force the lice to move slower, preventing them from escaping. A new brain-imaging study of mankinds best friend has found a striking similarity in how humans and dogs — and perhaps many other mammals — process voice and emotion. Like humans, dogs appear to possess brain systems that are devoted to making sense of vocal sounds, and are sensitive to their emotional content.

The law and the light book of Mormon Symposium, byu, ). Seeing a bear ride a bicycle in the circus or a parrot that speaks are part of the characteristics that many call humans, but there are species that share meaning with us more than we think. They have a name, british scientists have shown that bottlenose dolphins call their partners using individual whistle patterns. In other words, dolphins use something that is comparable to our names. Apparently, they develop their individual series of whistles as a hallmark from a very early age.
Tools, chimpanzees have always had a special ability to manipulate tools. Researchers at the max Planck Institute for evolutionary Anthropology in leipzig have found evidence in West Africa that demonstrates that chimpanzees have been splitting nuts with stone tools for the past 4,300 years. Social life, in Canada, two populations of orcas apparently maintain a culture of 700 thousand years old. "Residents" and "transients" temporarily share the habitat. However, they do not mate with each other and depend on different types of food. The "transients" eat mammals, while the "residents" eat fish. They never for give up their different habits.
Descartes argues that the absence of speech in animals could only be explained in animals lacking thought. Descartes was well aware. Excerpted from Alan White, rights (Oxford:Oxford University Press 1984). Reprinted by permission of Oxford University Press. That animals produce calls, cries, songs and various gestures that function to express their passions but argued that they never produce anything like declarative speech in which they use words or put together other signs, as we do in order to declare our thoughts. Humans grow and develop a stronger mentality and thought process.
Animals never grow up enough for any certain sign of thought to be detected in them. Animals are here for our needs what harms them really does not matter. Animals are here for a reason thus it is okay for humans to use them as ends to our means. So basically what animals feel, really does not matter because they are not human thus they cannot feel the same way that rational. Packer quorum of the Twelve the many similarities between the human body and the physical bodies of animals do not, in my mind, confirm a common ancestor. It confirms the sovereignty of physical laws. If a hip joint in a human body is of the same design as that in animals, it simply means that the ball and socket conforms to physical laws which govern space, stress, strength, motion, and articulation. If you want articulation, that design works in the flesh and bone of either man or animal, or for that matter in machines.

Ii, those who argue against animal rights argue that animals have father's no rights because they lack thought process. Alan White maintains that since animals, cannot, for example, claim, assert, or waive rights, they are not the kind of things that can have rights in the first place. Only a person can have rights, on Whites account. Animals have shown to be similar in imitating some actions like shredder humans. For example monkeys understand that people smoke cigarettes and thus they do the same action when given cigarettes and some have even become addicted to cigarettes just like humans. Also a group of military men where horsing around and where using their guns in front of a monkey and they gave the monkey a gun and the monkey started shooting at them. But the argument is that just because animals have similarities to humans does not automatically give them rights. Because if similarity is going to be applied, to be given rights, then a toy robotic dog, computers, and even radios behave in ways that are similar to ways that human beings behave.
Animals have feelings just like us humans and yes they are capable of feeling pain just like. Animals should have the right to be protected from humans that want to cause them any extreme cruelty and hardship. Animals are different species help than humans, but just because they are different than human beings does not mean they should not have rights. Morality rules should be applied and respected for all living things. My arguments are that animals have rights because they are living things thus they have the right to be defended and protected from those who want to cause them any harm or any type of cruelty. Animals should have rights to their lives, they should be able to live freely the way they please and not be held in captivity for humans entertainment. Animals are not ours to eat, wear, experiment on, use for entertainment, or abuse in any way.
and live in this world, that we now call Earth. Animals are able to adapt and survive in this world that humans have changed and adapted for human conformities and that now humans claim as theirs, even though animals where the first to live and inhabit this world. Animals are on planet Earth for a purpose but we are not aware of this because we do not have enough knowledge about animals. But that does not mean that the purpose is for us humans to abuse and use them as we please, just for our needs for food and for personal hobbies that include hunting: and for scientific studies that with out consent abuse animals for testing. Animals should be allowed to live free of fear of being captured and to not be removed from their natural habitat that they consider their home or to be brutally killed. Animals should be allowed to live the lives that they please as they please with no fears of being separated from their families.
However, there is another relationship: animals are abused or killed for no reason, for example as, people beat animals as cruelly as they want just to relieve negative feelings. Animals are killed by people for their fur and feathers, for food, for sport, and simply because they were in the way. As a result of proposal tremendous indiscriminate killing of animals which happens frequently, according to the analysis, species perish at the speed one kind of animals dying per hour on the earth. Actually, animals are more than just a source of food. Every animal has its place in the balance of nature. Destroying one kind of animal can create many problems. For instance, if flies become one day extinct, and the number of the creature who eats it, assuming to be birds, will sharply decrease because of no food to eat and similarly the creature who hunts for bird will gradually extinct as well and. Animals link with each other in food chain.

Imagine there is a paper locked room where a person, a tiger and a rabbit are. Without doubt, the tiger is forced to eat the rabbit to live; the person is forced to fight with the tiger for survival. This is the most basic relationship between animal and animal and between human and animal, based on the rule of the jungle. As we all know, even with much stronger ability of thinking, with high iq, people are still almost the same with animals- i mean physically. However, with the development of the species through evolution, people are possessed of a much stronger power which is the advanced technology than animals are, hence the relationship has changed. Besides eating animals as food, people now have the ability to control animals, and to train them, as assistances,. What is more, some of people gradually have affection to animals that they treat animals well as pets, and hope their pets keep them company.
