What kind of diet did early humans evolve with? How is that realted to what we eat today?

They had to catch it before they could eat. We just need to buy it.

HUMAN DIGESTIVE SYSTEM IS NOT DESIGNED FOR TOO Many veggies cause we have a very small caesum(part of long intestine), caesum is ysed for digesting veggies....so basically we are carnivores (cause we have sharp canines) but we need roughage which we get from veggies!

Determining the origin of agriculture is problematic since it pre-dates the invention of writing. Some authorities insist localized farming took place more than 10,000 years ago, while others believe the earliest systematic plantings/harvestings took place no more than 7,000 years ago. \n\nThe practice of agriculture is often used to distinguish the neolithic period from earlier parts of the stone age. The first crops that humans domesticated included wheat (einkorn and emmer) and barley. \n\nIt is clear that farming was invented at least twice, probably more often: once in the Fertile Crescent (some say by the Natufian culture, others say by the Sumerians), once in East Asia (rice), and once in Central America (maize, squash). \n\nMost likely, there was a gradual transition from a hunter-gatherer economy to an agricultural one, via a lengthy period when some crops were deliberately planted, and other foods were gathered from the wild. The reasons for the earliest introduction of farming may have included climate change. \n\nFarming allows a much greater density of population than can be supported by hunting and gathering, and the ability of farmers to feed large numbers of people whose activities have nothing to do with material production was the crucial factor in the rise of standing armies. \n\nAfter 1492, the world's agricultural patterns were shuffled in the widespread exchange of plants and animals known as the Columbian Exchange. Crops and animals that were previously only known in the Old World were now transplanted in the New, and vice versa. \n\nArchaeobotanists/Paleoethnobotanists have traced the selection and cultivation of specific food plant characteristics, such as a semi-tough rachis and larger seeds, to just after the Younger Dryas (about 9,500 BC) in the early Holocene in the Levant region of the Fertile Crescent. Limited anthropological and archaeological evidence both indicate a grain-grinding culture farming along the Nile in the 10th millennium BC using the world's earliest known type of sickle blades. \n\nThere is even earlier evidence for conscious cultivation and seasonal harvest: grains of rye with domestic traits have been recovered from Epi-Palaeolithic (10,000+ BC) contexts at Abu Hureyra in Syria, but this appears to be a localised phenomenon resulting from cultivation of stands of wild rye, rather than a definitive step towards domestication. It is not until ca. 8,500 BC, in middle-Eastern cultures referred to as Pre-Pottery Neolithic B (PPNB), where there is the first definite evidence for the emergence of a widespread subsistence economy that was dependent on domesticated plants and animals. \n\nIn these contexts lie the origins of the eight so-called founder crops of agriculture: firstly emmer wheat, einkorn wheat, then hulled barley, pea, lentil, bitter vetch, chick pea and flax. These eight crops occur more or less simultaneously on PPNB sites in this region, although the consensus is that wheat was the first to be sown and harvested on a significant scale. \n\nThere are many sites that date to between ca. 8,500 BC and 7,500 BC where the systematic farming of these crops contributed the major part of the inhabitants' diet. From the Fertile Crescent agriculture spread eastwards to Central Asia and westwards into Cyprus, Anatolia and, by 7,000 BC, Greece. Farming, principally of emmer and einkorn, reached northwestern Europe via southeastern and central Europe by ca. 4,800 BC. \n\nThe reasons for the earliest introduction of farming may have included climate change, but possibly there were also social reasons (e.g. accumulation of food surplus for competitive gift-giving). Most certainly there was a gradual transition from hunter-gatherer to agricultural economies after a lengthy period when some crops were deliberately planted and other foods were gathered from the wild.

Pinpointing the absolute beginnings of agriculture is problematic because the transition away from purely hunter-gatherer societies, in some areas, began many thousands of years before the invention of writing. Nonetheless, Archaeobotanists/Paleoethnobotanists have traced the selection and cultivation of specific food plant characteristics, such as a semi-tough rachis and larger seeds, to just after the Younger Dryas (about 9,500 BC) in the early Holocene in the Levant region of the Fertile Crescent.

By 8000 BC, farming was in practice in Anatolia. By 7000 BC it reached Mesopotamia, by 6000 BC the Nile River, and by 5000 BC, it had spread to India. Around the same time, agriculture was developed independently in China. Maize was first domesticated from teosinte in the Americas around 3000-2700 BC. In these contexts lie the origins of the eight so-called founder crops of agriculture: firstly emmer and einkorn wheat, then hulled barley, peas, lentils, bitter vetch, chick peas and flax. These eight crops occur more or less simultaneously on PPNB sites in this region, although the consensus is that wheat was the first to be sown and harvested on a significant scale.

Cambridge University Press; Harris, D. [ed.] 1996 The Origins and Spread of Agriculture in Eurasia. UCL Press).\n\n \nA tractor ploughing an alfalfa fieldThe reasons for the earliest introduction of farming may have included climate change, but possibly there were also social reasons (e.g. accumulation of food surplus for competitive gift-giving). Most certainly there was a gradual transition from hunter-gatherer to agricultural economies after a lengthy period when some crops were deliberately planted and other foods were gathered from the wild.

Baked clay. Field Museum.Full dependency on domestic crops and animals did not occur until the Bronze Age, by which time wild resources contributed a nutritionally insignificant component to the diet. If the operative definition of agriculture includes large scale intensive cultivation of land, mono-cropping, organized irrigation, and use of a specialized labour force, the title "inventors of agriculture" would fall to the Sumerians, starting ca. 5,500 BC. Intensive farming allows a much greater density of population than can be supported by hunting and gathering and allows for the accumulation of excess product to keep for winter use or to sell for profit. The ability of farmers to feed large numbers of people whose activities have nothing to do with material production was the crucial factor in the rise of standing armies. The agriculturalism of the Sumerians allowed them to embark on an unpreceden

Sorry to be picky, but we didn't evolve from monkeys, we evolved from apes!\n\nModern monkeys aren't the same as our and their common ancestors, they have evolved too! They've just changed in different ways to adapt to their environment. Evolution has made them very well adapted to living in trees, e.g. long prehensile tails and both "hands" and "feet" that can grip. Note that humans don't have these marvellous adaptations!\n\nWe got bigger brains, tool-making and language skills, and the ability to walk upright, which enabled us to thrive in environments that monkeys would struggle to survive in. But you try living in a tree and eating bananas all day and see how well adapted you are to that! Evolution has just treated us differently, that's all.

The history of technology is at least as old as humanity. Some primitive forms of tools have been discovered with almost every find of ancient human remains dating from the time of homo habilis). Nevertheless, other animals have been found to use tools—and to learn to use and refine tools—so it is incorrect to distinguish humans as the only tool-using or tool-making animal. The history of technology follows a progression from simple tools and simple (mostly human) energy sources to complex high-technology tools and energy sources.\n\nThe earliest technologies converted readily occurring natural resources (such as rock, wood and other vegetation, bone and other animal byproducts) into simple tools. Processes such as carving, chipping, scraping, rolling (the wheel), and sun-baking are simple means for the conversion of raw materials into usable products. Anthropologists have uncovered many early human habitations and tools made from natural resources. Birds and other animals often build elaborate nests and some simple tools out of various materials. We normally don't consider them to be performing a technological feat, primarily because such behavior is largely instinctive. There is some evidence of occasional cultural transferrence, especially among the other, nonhuman primates. Nevertheless, there is now considerable evidence of such simple technology among animals other than humans.\n\nThe use, and then mastery, of fire (circa 1,000,000 - 500,000 BC) was a turning point in the technological evolution of humankind, affording a simple energy source with many profound uses. Perhaps the first use of fire beyond providing heat was the preparation of food. This enabled a significant increase in the vegetable and animal sources of food, while greatly reducing perishability.\n\nThe use of fire extended the capability for the treatment of natural resources and allowed the use of natural resources that require heat to be useful. (The oldest projectile found is a wooden spear with fire hardened point, circa 250,000 BC.) Wood and charcoal were among the first materials used as a fuel. Wood, clay, and rock (such as limestone), were among the earliest materials shaped or treated by fire, for making artifacts such as weapons, pottery, bricks, and cement. Continuing improvements led to the furnace and bellows and provided the ability to smelt and forge native metals (naturally occurring in relatively pure form). Gold, copper, silver, and lead, were such early metals. The advantages of copper tools over stone, bone, and wooden tools were quickly apparent to early humans, and native copper was probably used from near the beginning of Neolithic times (about 8000 BCE). Native copper does not naturally occur in large amounts, but copper ores are quite common and some of them produce metal easily when burned in wood or charcoal fires.\n\nEventually, the working of metals led to the discovery of alloys such as bronze and brass (about 4000 BCE). The first uses of iron alloys such as steel dates to around 1400 BCE.\n\nMeanwhile, humans were learning to harness other forms of energy. The earliest known use of wind power is the sailboat. The earliest record of a ship under sail is shown on an Egyptian pot dating back to 3200 BCE. From prehistoric times, Egyptians probably used "the power of the Nile" annual floods to irrigate their lands, gradually learning to regulate much of it through purposely built irrigation channels and 'catch' basins. Similarly, the early peoples of Mesopotamia, the Sumerians, learned to use the Tigris and Euphrates rivers for much the same purposes. But more extensive use of wind and water (and even human) power required another invention.\n\nIt is still a mystery as to who invented the wheel and when and why it was invented. According to some archaeologists, it was probably originally invented about 8000 B.C. The wheel was almost certainly independently invented in Mesopotamia -— present-day Iraq.

yeah he had wood peckers and as to where he kept them i have no idea but i do know that all the animals had one diet in common. back then even lions ate leave and grass and herb not meat but after the flood the diet was changed.

the mink...  it is likely due to the fact that they have short, active lifespans... they need a constant, high energy diet but can not eat too much in one sitting..  during evolution, it's likely that there was little to no energy invested in development of the digestive tract because of its short lifespan...\n\nalso, being a carnivore, they have no need for a cecum and long digestive tract (like rabbits, sheep, and deer) which is useful in extracting the low amounts of energy from plant material...

Oh boy, there are about three relavant answers to that question.  First one is that a large meteor hit near Cancun Mexico, which sent wave after wave of dust into the atmosphere blocking out most of the suns rays, and killing off vegitation, causing herbavors to starve, which left the carnivores with nothing to eat.  Another theory is that they mearly evolved and were replaced with more capable species, which replaced them.  Yet another is that a very intense volcanic eruption occured (probably something like yellowstone) which did the same as the meteor would have.  It would've blocked out the sun, cooled the planet, and killed off most of the vegitation.

In a nutshell, the original Blood Type "O", hunters & gatherers, do best eating meat, fish, nuts, berries/fruits & eggs. Anything harvested naturally in the wild, and eaten fresh...minimal cooking. No processed foods. Roughly 50% of the human population, is still "O"...\nBlood Type "A", the first farmers to grow grain at the same location. They thrive on breads, cereal grains & vegetables, some fruits, some fish, less meat. They are most prone to cancers, and comprise roughly 30% of the population...\nBlood Type "B" were nomadic people, milking their transportion (Camels, cows, sheep, goats, etc.). This is the only Type that thrives on dairy products, and has the most balanced diet overall. Each new environment they encountered in their travels, had different foods available. They represent 15% of the people...\nBlood Type "AB" is the newest evolutionary Blood Type. It is only 1000 years old and combimes some of the traits of both "A" & "B". These are only 5% of the population...\n\nThat's roughly how it works, and health is more the focus, than dieting (losing weight) per se...

Noo we werent monkeys...\nit was said that we evovled from monkeys in other words we were ancestors. We humans look like monkeys, even a long time ago, because we share the common ancestors with the monkeys... It is believed that not too long ago (compared to the life history of the earth), a certain type of old ape started to evolve toward what ended up as humans today, but some of them also evolved toward the ape direction and gave rise to the apes of today. It is not hard to imagine why we look so similar to apes since really we have not had a time long enough to really diverge our appearance since we originated from the same ancestor.

ok.. so in the past, our smart ancestors needed all those teeth. as one of my colleagues has said, they needed to chew hard food and be crunching on those bones, meat and so on. but that's not it although they had large jaws (which in due time and evolution shrinked) they also didn't have toothpaste!!! so, their teeth would decay in time, and they would do anythg to get rid of those ones that pained them much (like bang it to a tree so that it falls, and or chew on a large apple so that tooth is stuck on it, w/o going to doctor to fix a small decay. so they would end up losing most of their teeth at the age of 18. but that was ok for they would have extra fantastic 4 to the rescue.\n\nnow, since we have toothpaste, and dentists and loads of other stuff to protect our teeth, our jaws shrunk and we were in all ways cooking food and not crunching on big nuts like desperate fools, rather use special tools to break nuts & so on. so, we proected our teeth, and eventually we don't need those extra four... which are a surplus extra by all means, and they would hurt our mouth when they come out... so BYE BYE ADDITIONAL MOLARS! OUCH!

Wisdom teeth are an evolutionary left over from when we evolved from Apes.  OUr diets were more fibrous and our jaws were longer.  We have since lost our tough diets and stopped evolving due to modern day diets our jaws grow less.\n\nIf you are a strict creationist.  ?????. . . Wisdom teeth are a spiritual challenge to your faith,  placed there by GOD.  For some unknown to us reason.

Man originated from earlier primates in eastern Africa. The big step in their evolution is the drying of eastern Africa about 4 million years ago. When the jungles died and separated, what would become man developed a locking knee joint. This enabled them to walk much farther (and endurance run) to cover more ground and obtain more resources, putting them at a distinct advantage to other primates. If you don't believe me, try walking around without locking your knee, it's hard and taxing.\n\nThis adaptation allowed for the development of many other things that we've come to love: our large heads and brains (when we were strictly bipedal, we free up our hands for projects, and this favors big brains), short rib cage (for flexibility), and big butts (something has to give you balance when you don't have a tail).\n\nThis climate change occurred when New Guinea moved in the way of a prominent current that brought warm, moist water to east Africa. Over time, these newly smart, adapted primates radiated out of Africa and to the rest of the world.
