the world's population will reach 7 billion
Only a tiny fraction of this number still makes a living by hunting and gathering
the way all our ancestors did before about 12,000 years ago
According to a set of claims relentlessly pushed in some books and blogs
as many modern humans as possible should adopt a hunter-gatherer diet
we should eat lean meat and vegetables because our Paleolithic hunting-and-gathering ancestors did
grains and sugars because our hunting-and-gathering ancestors didn't eat these items
I'd greet this embrace of the human prehistoric past with unalloyed delight
especially in a country where a high percentage of our population is evolution-averse
I don't think there's good science behind these claims
It's best to clarify right off that leaders of the paleo-diet movement don't think monolithically. Lean meat and veggies take center stage, but the emphasis may vary in details such as how much seafood to eat. A look at the current issue of Paleo — a magazine devoted to "modern primal living" — indicates that
paleo-faddists think hard about exercise and lifestyle choices
Some of them, in fact, take a paleo-lifestyle to startling lengths. In profiling this "modern-day Stone Age subculture" and its leaders, Arthur de Vany and Loren Cordain, the German magazine Der Spiegel interviews disciples who run through the undergrowth and eat wild boar in explicit emulation of their Paleolithic forebears
When I've interacted online with paleo-diet fans
I've found the great majority to be measured and thoughtful
I worried aloud about the consequences of urging even more carnivory than we've already got
But the paleo-movement seems to doom (even if unintentionally) more animals to life and death in factory farms
A greater percentage of grain crops would also be diverted to rich countries' animals and away from poor countries' people
What I learned is that some paleo-dieters reject the eating of animals from factory farms
focusing instead on avoiding grains and sugary foods
So no one should dismiss these people as blind fanatics
But do their core beliefs accord with good science
Many nutrition scientists give the paleo-diet a thumbs-down
They worry about its dearth of carbohydrates
and the fact that its boasts for good health are medically unproven
Our ancestors began to eat meat in large quantities around 2 million years ago
when the first Homo forms began regular use of stone tool technology
the diet of australopithecines and their relatives was overwhelmingly plant-based
I could argue that the more genuine "paleo" diet was vegetarian
More worrisome are persistent attempts to match a modern diet to an "average" Paleolithic one, or Loren Cordain's insistence that "we were genetically designed to eat lean meat and fish and other foods that made up the diet of our Paleolithic ancestors."
Here's where science most forcefully speaks back
ancient hunter-gatherer groups adapted to local environments that were regionally and seasonally variable — for instance
game-saturated or grain-abundant (eating grains was not necessarily incompatible with hunter-gatherer living)
People learned what worked in local context for survival and reproduction
cultural traditions began to play a role in who ate what
there was no single hunter-gatherer foraging strategy
and genes no more "designed" our eating behavior than they designed our language or our ways of relating between the genders
It's not paleo-fantasy that's going to help us negotiate a healthy future

German newspaper, inFranden.de reports that a Ferrari F12 Berlinetta crashed into a central reservation over the weekend
Fortunately neither driver nor passenger suffered injuries
Damage is quite heavy to the front with the right side rear fender and rear bumper damaged too
The accident happened near Allersberg on the derestricted section of the A9 autobahn
The Ferrari F12 Berlinetta is a thoroughbred Ferrari GT car
It features a 6.3 litre V12 engine with 730hp routed exclusively to the rear wheels
it is inevitable that one or two accidents were going to occur
The pictures reveal that a BMW M6 was also at the scene of the accident
