Man's best friend and when did man domesticated the wolf to become the beloved dog? Well studies show about 17,000 years ago. The following article is from interestingengineering.com and written by Nergis Firtina that looks at this topic:
""Wolf domestication occurred earlier than proposed until now."
A new study revealed a new link between dogs and humans. According to scientists, dog-human friendship dates back much earlier than we thought. That is, 17,000 years ago.
Thanks to an excavation led by Jesus Altuna in the Erralla cave (Zestoa, Gipuzkoa) in 1985, an almost complete family of carnivores, including wolves, dogs, foxes, and coyotes, among others, was unearthed. However, it was challenging to determine which canid species it was back in those days.
Fortunately, the team studying human evolution at the University of the Basque Country (UPV/EHU), under the direction of Professor Conchi de la Rúa, has managed to determine the bones' species. Canis lupus familiaris (domestic dogs) has been identified as the species using morphological, radiometric, and genomic investigation.
The study was published in the Journal of Archaeological Science: Reports.
As stated in the release, the humerus was directly dated with carbon-14 using particle accelerator mass spectrometry, and its age was determined to be 17,410–17,096 cal. That makes the Erralla dog one of the oldest household canines to have lived in Europe, having existed during the Upper Palaeolithic Magdalenian period.
“These results raise the possibility that wolf domestication occurred earlier than proposed until now, at least in western Europe, where the interaction of Palaeolithic hunter-gatherers with wild species, such as the wolf, may have been boosted in areas of glacial refuge (such as the Franco-Cantabrian) during this period of the climate crisis,” explained Conchi de la Rúa, head of the Human Evolutionary Biology group.
How were the dogs domesticated?
At the end of the Miocene epoch, 6 million years ago, the Earth's temperature began to drop gradually. This resulted in the Ice Age, also known as the glaciations of the Pliocene and Pleistocene. Only certain kinds of animals that could adapt to these changes would survive, as forests and savannahs were frequently replaced with steppes or grasslands.
Animal domestication is a coevolutionary process in which a population adapts to a novel habitat that includes another species with developing habits in response to selective pressure. The domestication of animals, which started with the long-term bond between wolves and hunter-gatherers more than 15,000 years ago, was one of the most significant changes in human history. Dogs were the first domesticated species, the only major carnivore known to have lived in close quarters with humans during the Pleistocene, and the only domesticated animal species overall.
Study abstract:
Dogs are known to be the first species domesticated by humans, although the geographic and temporal origin of this process is still under debate in different fields of knowledge. In the present study, we examined a humerus from a canid recovered in the Lower Magdalenian level of the site of Erralla (Zestoa, Gipuzkoa, Basque Country, Spain), combining morphology, radiocarbon dating and genetics. Our results confirm the identification of this specimen as Canis lupus familiaris, discarding miss-identification with a dhole (Cuon alpinus) through genetic analyses of cytochrome b gene and mtDNA haplogroup. The direct AMS 14C dating (17,410–17,096 cal. BP) indicated that the Erralla specimen represents one of the earliest domesticated dogs in Europe, in the Lower Cantabrian Magdalenian period. We discuss our results in the light of the debate of the origin of dogs, conducting a critical review of the datings of sites of Eurasia that have provided remains of Paleolithic and Mesolithic dogs, including the so-called “dog-like wolves”."
So man's best friend used to be a wolf and was domesticated somewhere around 17,000 years ago. Dogs have come a long way being semi-wild to the beloved pets today. Now I look at my 15 pound Jezzebell Pug and see her in a little different light now. Added my two wolf-dogs Jezzebell the Pug (Small) and Ava the Old English Bulldogge (Large dog)

I have lost a lot of faith with the Medical Community and the Governments over the last several years, but there are a few good things that can raise above the corruption and the pushing of drugs a new approach to heal people. The following is from www.gaia.com and written by Hunter Parsons that does not involve any drug or pushing an ineffective so called vaccine that the drug company is not held accountable in any way but they use sound! The use of sound can regrow bone tissue! Here is the story:
"The future of regenerative medicine could be found within sound healing by regrowing bone cells with sound waves.
The use of sound as a healing modality has an ancient tradition all over the world. The ancient Greeks used sound to cure mental disorders; Australian Aborigines reportedly use the didgeridoo to heal; and Tibetan or Himalayan singing bowls were, and still are, used for spiritual healing ceremonies.
Recently, a study showed an hour-long sound bowl meditation reduced anger, fatigue, anxiety, and ...
Not a fan of a Defense Agency studying Anti-Gravity and other Exotic Tech, but if the commercial world and make this technology cheap that will change our world yet again. The following is about three minute read and from www.gaia.com. The below was written by Hunter Parsons:
"Wormholes, invisibility cloaks, and anti-gravity — it’s not science fiction, it’s just some of the exotic things the U.S. government has been researching.
A massive document dump by the Defense Intelligence Agency shows some of the wild research projects the United States government was, at least, funding through the Advanced Aerospace Threat Identification Program known as AATIP.
And another lesser-known entity called the Advanced Aerospace Weapons System Application Program or AAWSAP

Of particular interest are some 1,600 pages released to Vice News, which ...
As our technology gets better we are discovering more about the history of mankind and pushing the timeline back further and further. The following article is from www.gaia.com and written by Michael Chary that discusses this new find that changes the historical timeline:
"Over the past decade, there have been a number of archeological revelations pushing back the timeline of human evolution and our ancient ancestors’ various diasporas. Initially, these discoveries elicit some resistance as archeologists bemoan the daunting prospect of rewriting the history books, though once enough evidence is presented to established institutions, a new chronology becomes accepted.
But this really only pertains to the era of human development that predates civilization — the epochs of our past in which we were merely hunter-gatherers and nomads roaming the savannahs. Try challenging the consensus timeline of human civilization and it’s likely you’ll be met with derision and rigidity.
Conversely, someone of an alternative...
Not sure if you have heard of a show on YouTube called "The Why Files". If not you should check it out it is interesting and has some humor with it on different subjects. Last weeks was on a different theory how the Universe works and how main stream Science is attempting to shut it down like is always seems to do if it goes aguest some special interest. Today it is akin to what happened to those who questioned the Earth was the Center of the Universe that main stream so called Science all believed during the Renaissance period, They called any theory that the Earth was not the Center of the Universe misinformation. Does this sound familiar today? People laughed and mocked people like Leonardo da Vinci, Nicolaus Copernicus, Georg Purbach as crack-pots, conspiracy theorists, nut-jobs and they were suppressed and even imprisoned for their radical thoughts and observations. Again it sounds like today in so many ways. In any event this is a good one to ponder and see even if a bad idea ...
Seemingly chaotic systems like the weather and the financial markets are governed by the laws of chaos theory.
We all have heard about chaos theory, but if you have not or have forgotten what chaos theory is well here you go from interestingengineering.com:
"Chaos theory deals with dynamic systems, which are highly sensitive to initial conditions, making it almost impossible to track the resulting unpredictable behavior. Chaos theory seeks to find patterns in systems that appear random, such as weather, fluid turbulence, and the stock market.
Since the smallest of changes can lead to vastly different outcomes, the long-term behavior of chaotic systems is difficult to predict despite their inherently deterministic nature.
As Edward Lorenz, who first proposed what became commonly known as the Butterfly Effect, eloquently said, "Chaos: When the present determines the future, but the approximate present does not approximately determine the future.""
You may have heard the term about chaos theory as a butterfly flaps its wings in Brazil,...
I for one have lost trust in Medical Doctors due to COVID and reflection that they seem to push pills for everything and untested so called vaccines that is using a unproven technology because the Government and the Medical Boards of the State told them to. There are a very few exceptions. Thus they do not address the key problem just prescribe more and more pills to keep you alive an sick longer for them and Big Phama to profit from you. Will AI do any better? Well that depends on what was used for the training of AI. If it also pushes pills and vaccines without question then you have the same problems noted above. However, if the AI Training includes all possible forms of treatment and they zero in on the right issues for the true problem then there is possibilities they would be way better than most of the current Medical Doctors today.
