This work encouraged us to do the first study of sleep, to our knowledge, in the platypus. In the platypus we saw sleep with vigorous rapid eye, bill and head twitching, identical in behaviour to that which defines REM sleep in placental mammals. Recording of the EEG in the platypus during natural sleep and waking states revealed that it had moderate and high-voltage cortical EEGs during this REM sleep state. The platypus not only has REM sleep, but it had more of it than any other animal. The lack of EEG voltage reduction during REM sleep in the platypus, and during the REM sleep-like state of the echidna, has some similarity to the sleep seen in neonatal sleep in placentals. The very high amounts of REM sleep seen in the platypus also fit with the increased REM sleep duration seen in altricial mammals. Our findings suggest that REM sleep originated earlier in mammalian evolution than had previously been thought and is consistent with the hypothesis that REM sleep, or a precursor state with aspects of REM sleep, may have had its origin in reptilian species.
Animals also dream. By destroying neurons in the brain stem that inhibit movement during sleep, researchers found that sleeping cats rose up and attacked or were startled by invisible objects—ostensibly images from dreams. By studying nonprimate animals, scientists have discovered additional neurophysiological aspects of REM sleep.
The absence of REM sleep in the echidna suggests that this stage of the sleep cycle evolved some 140 million years ago, when marsupials and placentals diverged from the monotreme line. (Monotremes were the first mammals to develop from reptiles.) By all evolutionary criteria, the perpetuation of a complex brain process such as REM sleep indicates that it serves an important function for the survival of mammalian species. Understanding that function might reveal the meaning of dreams.
REM sleep could have provided this new mechanism, allowing memory processing to occur “off-line.”
The subjects of dreams are broad-ranging and complex, incorporating self-image, fears, insecurities, strengths, grandiose ideas, sexual orientation, desire, jealousy and love.
when the hippocampus, which continues to develop after birth, becomes functional, REM sleep takes on its interpretive memory function. The waking information to be integrated at this point in development constitutes the basic cognitive substrate for memory—the concept of the real world against which later experiences must be compared and interpreted.
Without theta rhythm during REM sleep, the echidna would not be able to process information while it slept. (The echidna does, however, show theta rhythm when foraging for food.) For higher capabilities to develop, the prefrontal cortex would have to become increasingly large—beyond the capacity of the skull—unless another brain mechanism evolved.

nature of things
Personally I have always had more respect and compassion for animals . I have found wild animals are at times more human than human with feral children that have been taken in and raised as their own with their own off spring for example. But food is food and we need to eat if only we could kill only enough for what we need , sadly there there is so much wasted for nothing .

Maybe you can tell me why you won't eat your dog or cat? The pig is just as loyal and they have saved owners lives before therefore showing their deep effecton. what makes only the dog, cat and horse and some "pet" birds the lucky ones.

When my dog encounters people who act shady around her, she responds in like to their instinctual response: she barks or snarls at them. If, however, you approach her with kindness, she'll pick up that emotional approach and respond in like.
When she anticipates my going up stairs as indicating it's time for a walk - her logical faculties are serving an instinctual desire: to go for a walk. This again is no proof of self consciousness, but an unconscious process that facilitates the fulfillment of an instinctual need.
All this wonderfulness we experience with animals, ironically, is only recognized with regard to how they make us feel - and so elicits sentimental statements - but their stupidity, the proof that in their behavior alone they demonstrate for us how different we are from them - doesn't seem to trigger an intellectual reference point.
This could be because: this society is obsessed with emotion - and so fervently accepts those facts of experience which unites man with animals - and at the same time ignores those facts of experience which clearly separates us from them.
I live in Canada and have never seen nor known anyone to eat a horse.
But in Canada, a country rarely considered exotic, you can get raw horse in Vancouver (at Yoshi’s, a Japanese restaurant), horse steak in Toronto (at the bistro La Palette), and horse anything in Quebec—even a fast-food chain, the Belgian Frite Alors, sells horse tartare. (Horse is free of tuberculosis and tapeworms, and thus safer than beef to eat raw.)
As for eating cats and dogs. Already, I have a compunction about eating animals - but the thought of eating animals who are so close with humans - like cats and dogs and horses, is completely immoral.

When I got over to it I noticed our little 'weenie' dog had left a 'present' at the base of the blackberry. Did he know how important the plant is to me and intentionally try to help with fertilization?
Nah I am sure that present was just for you lol

Greetings, ATS!
Mods, wasn't sure where to put this, so please move if necessary. Thanks.
So I stumbled across a very interesting article on discoverynews and thought I'd share. If it turns out this is true, wow.
An international group of prominent scientists has signed The Cambridge Declaration on Consciousness in which they are proclaiming their support for the idea that animals are conscious and aware to the degree that humans are -- a list of animals that includes all mammals, birds, and even the octopus. But will this make us stop treating these animals in totally inhumane ways?
While it might not sound like much for scientists to declare that many nonhuman animals possess conscious states, it's the open acknowledgement that's the big news here. The body of scientific evidence is increasingly showing that most animals are conscious in the same way that we are, and it's no longer something we can ignore.
This is big news. In the past, we've always assumed animals were somehow less aware, less conscious than humans. But that may not be the case (although anyone who's spent time with animals knew this already)
The declaration made the following observations:
Studies of non-human animals have shown that homologous brain circuits correlated with conscious experience and perception can be selectively facilitated and disrupted to assess whether they are in fact necessary for those experiences
Wherever in the brain one evokes instinctual emotional behaviors in non-human animals, many of the ensuing behaviors are consistent with experienced feeling states, including those internal states that are rewarding and punishing.
Pharmacological interventions in non-human animals with compounds known to affect conscious behavior in humans can lead to similar perturbations in behavior in non-human animals.
So my question to you is this, ATS. Does this change the way you view animals? Should it change the way we treat animals, such as animals raised and slaughtered for food? Will it impact the way we treat animals?
Can't wait to hear your thoughts!
Arent humans the same?
I know that is apparently a part of the culture in Quebec, maybe it is a French connection. It is so much a part of the culture there that they serve it in fast food restaurants.

It's just not apart of the culture as eating dogs and cats is in China, is what I was trying to say.
In what sense are you saying we are same? Our self consciousness makes us different, because we are free to choose, whereas animals are not.

However, that does not mean we must not use them for science. Humans have dominion over all the animals to use as they see fit. As long as we are not unduly cruel to them, we should be able to use them for testing to help humanity as a whole. iIsee nothing wrong with that at all.

Before we will something, we may meet an instinct to act in a particular way; upon reflection, the human being can oppose that instinct to act, and act differently. By doing so man proves his ability to act free from external determination.
