Meni je zanimljiva ishrana kamenog doba tj.to je ishrana koja zapravo određuje naš organizam evolucijski kakav i danas imamo , dok su žitarice,mleko,so,šećer,...civlizacijska tekovina i zapravo veštačka iliti umjetna stvar i zato imamo problema sa zdravljem.

Ne pa nismo mi Kinezi da smo osjetljivi na laktozu. Mislim da je tih 10-ak tisuca godina bilo sasvim dovoljno da se prilagodimo na novu prehranu, dapace nas organizam danas i ocekuje da mu das mlijeka, zitarica itd.

Nije samo psenica dozivjela evoluciju, nego i nas prehrambeni sustav; svi skupa zajedno simbiotski evoluiramo.

Isto kao sto je psenica od divlje trave postala ovo sto imamo danas:

-veceg zrna
-boljeg okusa
-zrno ne pada na pod kada sazrije da bi se dalje razmnozavalo kao kod divlje psenice, nego ostaje na peteljci i doslovno "ceka" poljoprivrednika da ga ubere i njegovo razmnozavanje simbiotski ovisi o covjeku

tako mozemo pretpostaviti da su vecu sansu za prezivjeti imali ljudi koji su mogli svariti zitarice i mlijeko, i taj prirodni odabir je sigurno doveo do i evolucije naseg stomaka i unutarnjeg sustava za apsorpciju hranjivih sastojaka.

Tako da je ta paleo dijeta vjerojatno pogresna, jer nakon 10 000 godina evolucije to vise nije nasa ocekivana dijeta. Ima smisla jesti ono sto se jelo u 19. stoljecu (da izbacimo moderne trendove zasladjivanja I soljenja), ali ici toliko daleko kao kameno doba... ako cemo jos radikalnije onda mozemo jesti ono sto su jeli nasi preci bakterije prije 5 milijardi godina.

How long has our species been around? New fossils from Morocco push the evidence back by about 100,000 years.

The bones, about 300,000 years old, were unearthed thousands of miles from the previous record-holder, found in fossil-rich eastern Africa. The new discovery reveals people from an early stage of our species’ evolution, with a mix of modern and more primitive traits.

“They are not just like us,” said Jean-Jacques Hublin, one of the scientists reporting the find. But they had “basically the face you could meet on the train in New York.”

Coupled with other evidence, the Moroccan fossils suggest that Homo sapiens may have reached its modern-day form in more than one place within Africa, said Hublin, of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, and the College of France in Paris.

Previously, the oldest known fossils clearly from Homo sapiens were from Ethiopia, at about 195,000 years old.



It’s not clear just when or where Homo sapiens came on the scene in Africa. Hublin said he thinks an earlier stage of development preceded the one revealed by his team’s discovery.

We evolved from predecessors who had differently shaped skulls and often heavier builds, but were otherwise much more like us than, say, the ape-men that came before them. Our species lived at the same time as some related ones, like Neanderthals, but only we survive.

Hublin and others described the new findings in two papers released Wednesday by the journal Nature . The discovery could help illuminate how our species evolved, Chris Stringer and Julia Galway-Witham of the Natural History Museum in London wrote in a Nature commentary.

The Moroccan specimens were found between 2007 and 2011 and include a skull, a jaw and teeth, along with stone tools. Combined with other bones that were found there decades ago but not correctly dated, the fossil collection represents at least five people, including young adults, an adolescent and a child of around 8 years old. Analysis shows their brain shape was more elongated than what people have today.

“In the last 300,000 years, the main story is the change of the brain,” Hublin said.


When these ancient people lived, the site in Morocco was a cave that might have served as a hunting camp, where people butchered and ate gazelles and other prey. They used fire and their tools were made of flint from about 25 miles away.

So where did the fully modern human body develop? The researchers say evidence suggests primitive forms of Homo sapiens had already widely spread throughout Africa by around 300,000 years ago. The different populations may have exchanged beneficial genetic mutations and behaviors, gradually nudging each other toward a more modern form of the species, Hublin said. In this way, he said in an interview, modern Homo sapiens may have arisen in more than one place.

So if there’s a Garden of Eden, he said, it’s the continent as a whole.

Some experts who didn’t participate in the research called that idea possible, although not yet demonstrated. But John Shea, an anthropologist at Stony Brook University in New York, said it’s more useful to think of the different local populations as a single one, connected the same way a big city is connected by subway stops.

“These are parts of a network,” through which ideas and genes flowed, he said.

Shea said it made sense to find such old traces of early Homo sapiens in northwestern Africa. He agreed that it doesn’t mean our species first appeared there.

“When it comes to evidence for human origins in northwest Africa versus eastern Africa versus southern Africa, it’s a tie,” he wrote in an email.

Richard Potts of the Smithsonian Institution’s National Museum of Natural History said the Morocco fossils “appear to reflect the very early transition to Homo sapiens, very possibly denoting the outset of the lineage to which all people belong.”

The site is about 34 miles (55 kilometers) southeast of the coastal city of Safi, northwest of Marrakech. Its age was determined chiefly by analyzing bits of flint found there, and the authors concluded they were around 315,000 years old. Hublin said that since a different method suggested a younger age for the site, he considers the bones to be about 300,000 years old.

Richard Roberts of the University of Woollongong in Australia, an expert in determining ages of ancient sites, supported that conclusion.

“I’d say the authors have presented pretty convincing evidence for the presence of early modern humans at this site by 300,000 years ago and perhaps a little earlier,” Roberts wrote in an email.

Humans evolved at least 100,000 years earlier than previously thought in Morocco, palaeoanthropologists have discovered, debunking the theory that the Rift Valley of Ethiopia was the ‘cradle of mankind.’

The world’s oldest Homo sapiens fossils - which could represent the first human family - were excavated in a barite mine at Jebel Irhoud, 60 miles west of Marrakesh, and date to between 300,000 and 350,000 years old.

There is no Garden of Eden in Africa. Or if there is, it is the whole of Africa.

Until now, experts believed all humans living today descended from a population that lived in East Africa. The earliest examples of our species were found in the 1960s by Richard Leakey, at Omo Kibish in south-western Ethiopia dating from 195,000 years ago.
The new fossils, of three young adults, one adolescent and a child of around eight years old, prove that early modern humans were already established at Jebel Irhoud at least 300,000 years ago.

“There is this notion that somewhere in East Africa there is a Garden of Eden where are species first developed and then spread within Africa, and outside of Africa,” said Professor Jean-Jacques Hublin, of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany
Our results challenge this picture in many ways. Very early in the process we realised the site was much older than anyone could imagine and we came to the conclusion that the layer richest in hominids around the site was around 300,000 years, so that was much older than anything else in Africa.

“These dates were a big wow. This material represent the very root of our species. So there is no Garden of Eden in Africa. Or if there is, it is the whole of Africa.”

Fossil remains were first discovered by miners working at the Jebel Irhoud in the 1960s, who while digging a new gallery, hit a pocket of reddish sediment which collapsed, revealing stone artefacts, bone and a skull.

But initial dating suggested they were only 40,000 years old.

However experts were puzzled by the features of the bones which had some modern human traits, but also more ancient brain cavities.

So in 2004, experts at the Max Plank Institute began a painstaking new excavation to hunt for new fossils and re-date the stone tools using the latest scientific methods.
Using state-of-the-art scans and statistical shape analysis based on hundreds of measurements the experts were able to recreate a computer-generated image of the original face of one of the fossils, and found it was virtually indistinguishable from that of modern humans living today.

The only difference was a slightly more elongated braincase, which would have held a different shaped brain.

Reporting their findings at a press briefing, Prof Hublin said: “It’s not just that we have an older date for the older forms of Homo sapiens but also it allowed us to envision a rather more complex picture for the emergence of our species with different parts of our anatomy evolving at different rates.

“There is an idea that humans like us appeared rather quickly but our results show this is very unlikely to be true.

“The story of our species in the last 300,000 years is mostly the evolution of our brain.”

Dr Philipp Gunz, of the Max Plank Institute added: "Our findings suggest that modern human facial morphology was established early on in the history of our species, and that brain shape, and possibly brain function, evolved within the Homo sapiens lineage.
The fossils were found in deposits containing animal bones showing evidence of having been hunted, with the most frequent species being gazelle.

By looking at the animals present, archaeologists were able to recreate the landscape and climate from the time, to give a picture of the environment for our early ancestors.

"Conditions were wetter than they were today, a little bit more humid, a landscape that is still open but with some clumps of trees, a sort of mixed environment,” added Max Planck Institute archaeologist Shannon McPherron.

“The site itself is in a hill and at the time of occupation would have been a cave, would have provided shelter and we found animal bones and stone tools which they would have used to process and consume those animals.

“We also find evidence of the fires that they had and the overall picture that one gets is a kind of hunting encampment, a place where people were passing through the landscape and spending the night, taking shelter there in search of subsistence.”

The new discoveries were reported in the journal Nature.

Hm..nadam se da se radi o lapsusu i da ne vidis zaista zenke u njima.

Ovo su djeca.

Pojava i razvoj civilizacije je doveo do degeneracije ljudske rase.
Prapovijesni ljudi bili su inteligentniji i sposobniji od današnjih ljudi, imali su veće mozgove, bili zdraviji, izdržiljiviji.
Degeneracija ljudske rase sa razvojem znanosti i tehnologije se samo ubrzala, što će i naposljetku dovesti i do nestanka ljudske rase i prije nego većina ljudi misli.
