Fossil fruit from 52 million years ago revealed   BBC - January 5, 2017
A fossilized fruit dating back 52 million years has been discovered in South America. The ancient berry belongs to a family of plants that includes popular foods such as potatoes, tomatoes and peppers. The plant family's early history is largely unknown as, until now, only a few seeds have been found in the fossil record. Scientists say the origins of the class go back much further than previously thought, by tens of millions of years.




Every grain of rice: Ancient rice DNA data provides new view of domestication history   PhysOrg - July 26, 2016
Despite its importance on global palates and economies, the domestication and origins of rice have remained a mystery. The popular consensus is that japonica, the shorter stickier grain perfect for sushi, has been exclusively cultivated exclusively in northern part of East Asia. In northern parts of East Asia, consisting of Japan, Korea, and northern part of China, current rice production and consumption are japonica with very little exceptional use of indica.




Farming was spread into and across Europe by people originating in modern-day Greece and Western Turkey   PhysOrg - June 6, 2016
Early farmers from across Europe have an almost unbroken trail of ancestry leading back to the Aegean. For most of the last 45,000 years Europe was inhabited solely by hunter-gatherers. About 8,500 years ago a new form of subsistence - farming - started to spread across the continent from modern-day Turkey, reaching central Europe by 7,500 years ago and Britain by 6,100 years ago. This new subsistence strategy led to profound changes in society, including greater population density, new diseases, and poorer health. Such was the impact of farming on how we live that scientists have debated for more than 100 years how it was spread across Europe. Many believed that farming was spread as an idea to European hunter-gatherers but without a major migration of farmers themselves.




New support for human evolution in grasslands: A 24-million-year record of African plants plumbs deep past   PhysOrg - June 6, 2016
Buried deep in seabed sediments off east Africa, scientists have uncovered a 24-million-year record of vegetation trends in the region where humans evolved. The authors say the record lends weight to the idea that we developed key traits - flexible diets, large brains, complex social structures and the ability to walk and run on two legs - while adapting to the spread of open grasslands.




How diet shaped human evolution   Science Daily - March 30, 2016
Homo sapiens, the ancestor of modern humans, shared the planet with Neanderthals, a close, heavy-set relative that dwelled almost exclusively in Ice-Age Europe, until some 40,000 years ago. Black carbon image of hunting on sandstone. The Ice-Age diet -- a high-protein intake of large animals -- triggered physical changes in Neanderthals, namely a larger ribcage and a wider pelvis. Neanderthals were similar to Homo sapiens, with whom they sometimes mated -- but they were different, too. Among these many differences, Neanderthals were shorter and stockier, with wider pelvises and rib-cages than their modern human counterparts.




New research shows same growth rate for farming, non-farming prehistoric people   PhysOrg - December 21, 2015
Prehistoric human populations of hunter-gatherers in a region of North America grew at the same rate as farming societies in Europe, according to a new radiocarbon analysis. Transitioning farming societies experienced the same rate of growth as contemporaneous foraging societies.




Scientists peg Anthropocene to first farmers   Science Daily - December 17, 2015
A new analysis of the fossil record shows that a deep pattern in the structure of plant and animal communities remained the same for 300 million years. Then, 6,000 years ago, the pattern was disrupted--at about the same time that people started farming in North America and populations rose. The research suggests that humans were the cause of this profound change in nature.




Eat a paleo peach - first fossil peaches discovered in southwest China   PhysOrg - December 1, 2015

The sweet, juicy peaches we love today might have been a popular snack long before modern humans arrived on the scene. Scientists have found eight well-preserved fossilized peach endocarps, or pits, in southwest China dating back more than two and a half million years. Despite their age, the fossils appear nearly identical to modern peach pits.




Shift in human ancestors' diet earlier than previously thought   Science Daily - September 15, 2015

Pre-humans' shift toward a grass-based diet took place about 400,000 years earlier than experts previously thought, providing a clearer picture of a time of rapid change in conditions that shaped human evolution. Millions of years ago, our primate ancestors turned from trees and shrubs to search for food on the ground. In human evolution, that has made all the difference. The shift toward a grass-based diet marked a significant step toward the diverse eating habits that became a key human characteristic, and would have made these early humans more mobile and adaptable to their environment.




Ancient DNA reveals how Europeans developed light skin and lactose tolerance   PhysOrg - June 11, 2015
Food intolerance is often dismissed as a modern invention and a "first-world problem". However, a study analyzing the genomes of 101 Bronze-Age Eurasians reveals that around 90% were lactose intolerant. The research also sheds light on how modern Europeans came to look the way they do - and that these various traits may originate in different ancient populations. Blue eyes, it suggests, could come from hunter gatherers in Mesolithic Europe (10,000 to 5,000 BC), while other characteristics arrived later with newcomers from the East. About 40,000 years ago, after modern humans spread from Africa, one group moved north and came to populate Europe as well as north, west and central Asia. Today their descendants are still there and are recognizable by some very distinctive characteristics. They have light skin, a range of eye and hair colors and nearly all can happily drink milk.




Our ancient obsession with food   PhysOrg - June 6, 2015

Amateur cook-offs like the hugely popular Master Chef series now in its seventh season in Australia have been part of our TV diet for almost two decades. These shows celebrate the remarkable lengths we humans will go to to whet the appetite, stimulate the senses, fire our neural reward systems and sustain the body. Yet, few of us pause to reflect on the hugely important role diet plays in the ecology and evolutionary history of all species, including our own. So much of what we read about human evolution portrays the protagonists as unwitting players in a game of chance: natural selection acting through external environmental factors beyond their control and sealing their evolutionary fate. Yet, all species influence their environment through the normal ecological interactions that occur in every ecosystem, such as between predators and their prey. Such interactions shape ecosystems over long time scales and are profoundly important in terms of evolution. When a species alters its environment and influences its own evolution, becomes as 'co-director' if you will, the process is dubbed 'niche construction'.




Scientists find evidence of wheat in UK 8,000 years ago   BBC - February 27, 2015
Wheat was present in Britain 8,000 years ago, according to new archaeological evidence. Fragments of wheat DNA recovered from an ancient peat bog suggests the grain was traded or exchanged long before it was grown by the first British farmers. The grain was found at what is now a submerged cliff off the Isle of Wight.




Tooth Tales: Prehistoric Plaque Reveals Early Humans Ate Weeds   Live Science - July 17, 2014

When looking for a meal, prehistoric people in Africa munched on the tuberous roots of weeds such as the purple nutsedge, according to a new study of hardened plaque on samples of ancient teeth. Researchers examined the dental buildup of 14 people buried at Al Khiday, an archeological site near the Nile River in central Sudan. The skeletons date back to between about 6,700 B.C., when prehistoric people relied on hunting and gathering, to agricultural times, at about the beginning of the first millennium B.C. The researchers collected samples of the individuals' dental calculus, the hardened grime that forms when plaque accumulates and mineralizes on teeth. Such buildup is fairly common in prehistoric skeletons, the researchers said.




Oldest human feces shows Neanderthals ate vegetables   BBC - June 26, 2014

Analysis of the oldest reported trace of human feces has added weight to the view that Neanderthals ate vegetables. Found at a dig in Spain, the ancient excrement showed chemical traces of both meat and plant digestion. An earlier view of these early humans as purely meat-eating has already been partially discredited by plant remains found in their caves and teeth.


Did Neanderthals eat their vegetables?   PhysOrg - June 25, 2014
The popular conception of the Neanderthal as a club-wielding carnivore is, well, rather primitive, according to a new study conducted at MIT. Instead, our prehistoric cousin may have had a more varied diet that, while heavy on meat, also included plant tissues, such as tubers and nuts.




Paleo diet didn't change – the climate did   PhysOrg - March 19, 2014
Why were Neanderthals replaced by anatomically modern humans around 40,000 years ago? One popular hypothesis states that a broader dietary spectrum of modern humans gave them a competitive advantage on Neanderthals. Geochemical analyses of fossil bones seemed to confirm this dietary difference. Indeed, higher amounts of nitrogen heavy isotopes were found in the bones of modern humans compared to those of Neanderthals, suggesting at first that modern humans included fish in their diet while Neanderthals were focused on the meat of terrestrial large game, such as mammoth and bison.




Paleo Diet May Have Included Some Sweets, Carbs   Live Science - January 6, 2014
The teeth from skeletons unearthed in the Grotte des Pigeons cave in Morocco reveal evidence of extensive tooth decay and other dental problems, likely a result of their acorn-rich diet. Ancient hunter-gatherers from the area that is now Morocco had cavities and missing teeth, a new study finds. The rotten teeth on the ancient skeletons, which date back to about 15,000 years ago, probably resulted from a carbohydrate-rich diet full of acorns. The findings show that at least some ancient populations were loading up on carbs thousands of years before the cultivation of grain took hold




Cavemen discovered recycling   PhysOrg - October 11, 2013
If you thought recycling was just a modern phenomenon championed by environmentalists and concerned urbanites - think again. There is mounting evidence that hundreds of thousands of years ago, our prehistoric ancestors learned to recycle the objects they used in their daily lives. Just as today we recycle materials such as paper and plastic to manufacture new items, early hominids would collect discarded or broken tools made of flint and bone to create new utensils




'Ancient humans' used toothpicks   BBC - October 8, 2013
"Ancient humans" used toothpicks nearly 1.8 million years ago, a study of their teeth has revealed. A team studied hominid jaws from the Dmanisi Republic of Georgia - the earliest evidence of primitive humans outside Africa. They also found evidence of gum disease caused by repeated use of what must have been a basic toothpick. Writing in PNAS, the team says its findings help to explain the diversity found in hominid teeth. The researchers used a new forensic approach to look at variations on the teeth of hominids thought by some to be early European ancestors. Teeth can shed light on what the individuals ate and how old they may have been, but until now it was not clear why there was so much diversity in the Georgian hominid mandibles, or jaws.




Prehistoric Europeans spiced their cooking   BBC - August 22, 2013
Europeans had a taste for spicy food at least 6,000 years ago, it seems. Researchers found evidence for garlic mustard in the residues left on ancient pottery shards discovered in what is now Denmark and Germany. The spice was found alongside fat residues from meat and fish.




Prehistoric Europeans Liked Spicy Food, Study Suggests   Live Science - August 22, 2013

A piece of an ancient cooking pot with some blackened foodresidue on it. The pottery shard, excavated from an archaeological site in northern Europe, is more than 6,000 years old.




Early humans in Iran were growing wheat 12,000 years ago   MSNBC - July 4, 2013

Stone tools and clay artifacts were collected from a site in the Zagros Mountains in Iran, where humans were cultivating plants 12,000 years ago. Among stone grinding tools, clay figures shaped like humans and animals and carved bone artifacts, archaeologists have harvested ancient grains from an early human settlement that are preserved 12,000 years. The finds suggest that generations of communities were earnestly experimenting with plant cultivation since the last Ice Age, and that agriculture, which laid the foundations for later civilizations, emerged concurrently in a number of locations that archaeologists recognize as the "Fertile Crescent" of the near east.




Salmon hot pot: earliest pottery was used to cook fish   Telegraph.co.uk - April 10, 2013
Archaeologists have found that charred shards some of the world’s oldest ceramic pots still contain residues of the food that was cooked in them. It is helps provide evidence of why hunter gatherer societies first began making pottery. Previously it was thought that ceramic pot emerged with the advent of farming 10,000 years ago as a way to store food. But pottery dating back more than 20,000 years has been discovered recently and has left historians baffled as to why the nomadic people who lived at the time would have gone to the effort of making such heavy pots.




Early human ancestors had more variable diet: Dietary preferences of 3 groups of hominins reconstructed   PhysOrg - August 8, 2012
The latest research sheds more light on the diet and home ranges of early hominins belonging to three different genera, notably Australopithecus, Paranthropus and Homo – that were discovered at sites such as Sterkfontein, Swartkrans and Kromdraai in the Cradle of Humankind, about 50 kilometres from Johannesburg. Australopithecus existed before the other two genera evolved about 2 million years ago.




No nuts for 'Nutcracker Man': Early human relative apparently chewed grass instead   PhysOrg - May 2, 2011
For decades, a 2.3 million- to 1.2 million-year-old human relative named Paranthropus boisei has been nicknamed Nutcracker Man because of his big, flat molar teeth and thick, powerful jaw. But a definitive new University of Utah study shows that Nutcracker Man didn’t eat nuts, but instead chewed grasses and possibly sedges - a discovery that upsets conventional wisdom about early humanity’s diet.




Why the switch from foraging to farming?   PhysOrg - March 7, 2011
Thousands of years ago, our ancestors gave up foraging for food and took up farming, one of the most important and debated decisions in history.




Coca leaves first chewed 8,000 years ago, says research   BBC - December 2, 2010
Peruvian foraging societies were already chewing coca leaves 8,000 years ago, archaeological evidence has shown. Ruins beneath house floors in the northwestern Peru showed evidence of chewed coca and calcium-rich rocks. Such rocks would have been burned to create lime, chewed with coca to release more of its active chemicals.

Prehistoric man ate flatbread 30,000 years ago: study   PhysOrg - October 19, 2010
Starch grains found on grinding stones suggest that prehistoric man may have consumed a type of bread at least 30,000 years ago in Europe, US researchers said.




Fossils of earliest land plants discovered in Argentina   BBC - October 12, 2010

The discovery puts back by 10 million years the colonization of land by plants, and suggests that a diversity of land plants had evolved by 472 million years ago. The newly found plants are liverworts, very simple plants that lack stems or roots.




Tool-making and meat-eating began 3.5 million years ago   BBC - August 11, 2010

Researchers have found evidence that hominins - early human ancestors - used stone tools to cleave meat from animal bones more than 3.2 million years ago. That pushes back the earliest known tool use and meat-eating in such hominins by more than 800,000 years.




Human Ancestors Were Homemakers   Live Science - December 18, 2009
In a stone-age version of "Iron Chef," early humans were dividing their living spaces into kitchens and work areas much earlier than previously thought, a new study found. So rather than cooking and eating in the same area where they snoozed, early humans demarcated such living quarters. Archaeologists discovered evidence of this coordinated living at a hominid site at Gesher Benot Ya‘aqov, Israel from about 800,000 years ago. Scientists aren't sure exactly who lived there, but it predates the appearance of modern humans, so it was likely a human ancestor such as Homo erectus.

Exploring the Stone Age pantry   PhysOrg - December 18, 2009
The consumption of wild cereals among prehistoric hunters and gatherers appears to be far more ancient than previously thought, according to a University of Calgary archaeologist who has found the oldest example of extensive reliance on cereal and root staples in the diet of early Homo sapiens more than 100,000 years ago.




A 200,000-year-old cut of meat   PhysOrg - October 15, 2009
New finds unearthed at Qesem Cave in Israel suggest that during the late Lower Paleolithic period (between 400,000 and 200,000 years ago), people hunted and shared meat differently than they did in later times. Instead of a prey's carcass being prepared by just one or two persons resulting in clear and repeated cutting marks -- the forefathers of the modern butcher cut marks on ancient animal bones suggest something else.




Diet, population size and the spread of modern humans into Europe   PhysOrg - August 11, 2009
Research suggests that at least some of the European early modern humans consistently consumed fish, supplementing their diet of terrestrial animals. Accumulating carbon and nitrogen stable isotope data from fossil humans in Europe is pointing towards a significant shift in the range of animal resources exploited with the spread of modern humans into Europe 40,000 years ago. Both the preceding Neandertals and the incoming modern humans regularly and successfully hunted large game such as deer, cattle and horses, as well as occasionally killing larger or more dangerous animals. There is little evidence for the regular eating of fish by the Neanderthals.




Early human hunters had fewer meat-sharing rituals   PhysOrg - August 13, 2009
A University of Arizona anthropologist has discovered that humans living at a Paleolithic cave site in central Israel between 400,000 and 250,000 years ago were as successful at big-game hunting as were later stone-age hunters at the site, but that the earlier humans shared meat differently. The Qesem Cave people hunted cooperatively, then carried the highest quality body parts of their prey to the cave, where they cut the meat with stone blade cutting tools and cooked it with fire. "Qesem" means "surprise." The cave was discovered in hilly limestone terrain about seven miles east of Tel-Aviv not quite nine years ago, during road construction.




Neanderthals wouldn't have eaten their sprouts either   PhysOrg - August 12, 2009
Spanish researchers say they're a step closer to resolving a "mystery of evolution" -- why some people like Brussels sprouts but others hate them. They have found that a gene in modern humans that makes some people dislike a bitter chemical called phenylthiocarbamide, or PTC, was also present in Neanderthals hundreds of thousands of years ago. The scientists made the discovery after recovering and sequencing a fragment of the TAS2R38 gene taken from 48,000-year-old Neanderthal bones found at a site in El Sidron, in northern Spain




Humans Ate Fish 40,000 Years Ago   Live Science - July 7, 2009
At least one of our ancestors regularly ate fish 40,000 years ago, a new study finds. Scientists analyzed chemical compositions of the protein collagen in an ancient human skeleton from Tianyuan Cave near Beijing to reach their conclusion. Fishing at this time must have involved considerable effort, the researchers think, because fossil records suggest humans were not using sophisticated tools - beyond crude stone blades - until about 50,000 years ago.




Mammals 'Got Milk' for Past 160 Million Years   Live Science - May 12, 2009
Moms today are strongly encouraged to nurse their babies. Mother's milk is more nourishing than formula and provides infants with some immune protection. This makes intuitive sense. Mammals and milk go together - it is produced by all species in this group and apparently has been for at least 160 million years. A new study looks at the genes that produce milk among seven species of mammals, including us, and finds that all of them share a lot of the same milk-making genes but not all species deliver the same milk. In fact, the milk might be tailored to the specific immune system needs of the animals.




Chocolate Origins Traced to Beer Makers 3,000 Years Ago National Geographic - November 13, 2007
People have been enjoying chocolate for more than 3,000 years - about 500 years earlier than previously believed, according to a new study. Researchers also think that chocolate was discovered by accident - when Central American Indians making beer from the pulp of cacao seedpods found a new use for a byproduct of that process.




African Cave Yields Earliest Proof of Beach Living National Geographic - October 17, 2007
The earliest modern humans probably arose on the savannas of East Africa, but a new study shows they soon learned that life could be good on the beach. Excavation of a sea cave on the tip of South Africa has shown that by 165,000 years ago people were already living near the coast and relying heavily on a diet of shellfish.




Fossil Meat Found in 380-Million-Year-Old Fish National Geographic - February 12, 2007
Australian scientists say they have found morsels of fossilized muscle - the oldest vertebrate tissue ever known—in the remains of two fish that lived 380 to 384 million years ago. Unearthed in western Australia 20 years ago, the specimens belong to two species of an extinct group of primitive, armored fish known as placoderms.




Americans Cooked With Chili Peppers 6,000 Years Ago, Study Finds National Geographic - February 15, 2007
Domesticated chili peppers started to spice up dishes across the Americas at least 6,000 years ago, according to new research tracing the early spread of the crop. Peppers quickly spread around the world after Christopher Columbus brought them back to Europe at the end of the 15th century, but their ancient history had been poorly known until now.




Oldest noodles unearthed in China BBC - October 12, 2005

Domesticated chili peppers started to spice up dishes across the Americas at least 6,000 years ago, according to new research tracing the early spread of the crop. Peppers quickly spread around the world after Christopher Columbus brought them back to Europe at the end of the 15th century, but their ancient history had been poorly known until now.




Oldest hamster food store found - 17 million year old nuts BBC - December 2003
A hoard of nuts buried by a rodent 17 million years ago is the oldest food larder so far discovered in the fossil record, say scientists in Germany. A team from the University of Bonn found a burrow containing 1,800 fossilized nuts when digging at an open-cast mine near Garzweiler. The winter food supplies were probably hidden away by a large hamster.
