Farming and Sericulture Producing food by cultivating crops and raising animals was a most important step forward in the development of human history. Around 10, years ago, people moved from an economy of gathering to one of producing, and entered the New Stone Age. Before that, people maintained their lives by picking wild fruits and other plants, and hunting animals. In order to look for food, they lived a nomadic life, but cultivation of grain crops made them settle down, thus the earliest villages appeared. Ruins of the New Stone Age can be found throughout China’s north and south. China was one of the first countries to see the emergence of agriculture. Finds at the ruins of the Hemudu Culture in Yuyao and the site of the matriarchal society at Banpo Village near Xi’an, which all date back 6, to 7, years, include rice, millet and spade-like farm tools made of stone or bone.

So suggests new research that tracked changes in two genes thought to help regulate brain growth, changes that appeared well after the rise of modern humans , years ago. That the defining feature of humans — our large brains — continued to evolve as recently as 5, years ago, and may be doing so today, promises to surprise the average person, if not biologists.
Lahn and colleagues examined two genes, named microcephalin and ASPM, that are connected to brain size. If those genes don’t work, babies are born with severely small brains, called microcephaly. Using DNA samples from ethnically diverse populations, they identified a collection of variations in each gene that occurred with unusually high frequency.
Agriculture was the foundation of the Ancient Greek economy. Nearly 80% of the population was involved in this activity.
Each of the pictured bottles has a relatively short description and explanation including estimated dates or date ranges for that type bottle and links to other view pictures of the bottle. Additional links to images of similar bottles are also frequently included. The array of references used to support the conclusions and estimates found here – including the listed dating ranges – are noted.
Additional information and estimates are based on the empirical observations of the author over 50 years of experience; this is often but not always noted. Various terminology is used in the descriptions that may be unfamiliar if you have not studied other pages on this site. If a term is unfamiliar, first check the Bottle Glossary page for an explanation or definition. As an alternative, one can do a search of this website. Figured Flasks Figured flasks is a generic name for the large class of liquor flasks primarily produced between and Due to their esthetic and decorative nature, these flasks were infrequently discarded unless broken so many survived to the present day.
Figured flasks also include c alabash bottles example below , which are covered separately here because of their distinctive shape, and some flasks that fit the form description but are just embossed with lettering, i. Unlike most other types of liquor bottles which are generally more common without embossing, figured flasks are by definition embossed since the embossed motifs and molded designs are what defines them as figured flasks, though many shapes are also unique to this group e.
Unembossed flasks with shapes similar to some of the later s primarily figured flasks are considered generically in the “Flask not considered figured ” category. The figured flasks described here represent a small cross-section of the hundreds of different types made during their heyday.
Source Would You Swap This For example, astronomy informed us that our tiny, fragile blue planet is just one of billions of celestial bodies rather than the bright centre of the universe. Biology showed us that like all other species, we evolved gradually over millions of years, rather than being created spontaneously by a supernatural being. Archaeology meanwhile is presently destroying another long held belief of human society; that our history over the last 10, years has been a continuous and glorious tale of progress.
Recent discoveries in the Middle East, Southern Europe and elsewhere have suggested that the discovery of agriculture, far from being a giant stride towards a better life, represented nothing more than a disaster, one from which we have yet to recover. For example, agriculture facilitated the onset of substantial social and sexual inequality, as well numerous diseases that continue to haunt our lives today.

Mesoamerica An understanding of Mesoamerican agricultural origins is hampered by the fact that few archaeological sites pertinent to the question have been explored. Several squash seeds that are larger than those from wild squashes have also been found at this site, indicating that domestication was occurring. One of the largest of these seeds has been directly dated to 10, bp, making it among the oldest evidence for a domesticated plant in the Americas.
Local experimentation with foxtail grass seems to have led to a failed domestication attempt. Cotton pollen and seeds that may be from the domesticated sunflower Helianthus species have also been recovered there and dated to bp. However, the sunflower is problematic because all available evidence is for its domestication in eastern North America , suggesting that the Mexican specimens may belong to another species.
Low-density, highly mobile Preceramic populations were responsible for these developments. Among the wild grasses—including teosintes e. In one model a series of massive mutations has been proposed to account for the development of the corn cob, but how to account for these mutations is problematic. Instead of requiring mutations , a recent genetic analysis indicates that a third grass, gamma grass Tripsacum dactyloides , crossed with teosinte to produce a hybrid with the cob structure typical of corn.
Although teosinte is not particularly palatable , Tripsacum has a history of being used for food. People may have recognized teosinte-Tripsacum crosses in the wild and selected them for planting. Another possibility is that teosinte and early corn were exploited first for the sugar content of their stalks and leaves. Ancient Mexicans chewed the leaves and stalks of early corn for their sweet flavour, and the sugar and starch from corn were also useful in making alcohol , an important comestible in many types of social interactions.

Local apples were used for pie. Baking powder came in different strengths single, double acting. Did you know some culinary historians say we Americans measure with objects as opposed to weight because of our pioneer heritage? Family recipes specifying “5 tins” of sugar are among the most challenging. The omission of flour measures is brilliant. Prior to modern supermarket flour, this variable item created different products according to grain, grind, season, and storage.
The Incas was the largest Empire in South America in the Pre-Columbian era. This civilization flourished in the areas of present-day Ecuador, Peru, and Chile and had its administrative, military and political center located at Cusco which lies in modern-day Peru.
Department of Agriculture Overview The U. USDA duties range from helping farmers with price support subsidies, to inspecting food to ensure the safety of the American public. The department seeks to expand overseas markets for U. USDA farm subsidies have been the subject of much controversy for decades as critics say the assistance is distributed unevenly and manipulates the agricultural market.
The department has also come under scrutiny for its failure to adequately protect American consumers from tainted foods that are not processed properly at slaughterhouses and other facilities. The current Secretary of Agriculture is Tom Vilsack. The earliest precursor to the U. In , President Abraham Lincoln created the U.
Growing up on a farm, Lincoln was a strong advocate for homesteading, railroad expansion, and land grants to fund agricultural and engineering colleges. He often praised technological advancements in agriculture, such as using horse-drawn machines instead of manual labor and the potential usefulness of steam plows. In , a case of imported animals that had been identified as diseased livestock prompted Congress to pass an act to quarantine imported animals.
Congress passed the act, but gave regulation duties to the Treasury Department, which did little to fix the problem. As a result, veterinarians and ranchers pushed for a more regulated solution.

Origin hypotheses[ edit ] Indigenous Australian camp by Skinner Prout, Scholars have developed a number of hypotheses to explain the historical origins of agriculture. Studies of the transition from hunter-gatherer to agricultural societies indicate an antecedent period of intensification and increasing sedentism ; examples are the Natufian culture in the Levant , and the Early Chinese Neolithic in China. Current models indicate that wild stands that had been harvested previously started to be planted, but were not immediately domesticated.
An abundance of readily storable wild grains and pulses enabled hunter-gatherers in some areas to form the first settled villages at this time. List of food origins Sumerian harvester’s sickle, BC, made from baked clay Early people began altering communities of flora and fauna for their own benefit through means such as fire-stick farming and forest gardening very early. An example is the semi-tough rachis and larger seeds of cereals from just after the Younger Dryas about BC in the early Holocene in the Levant region of the Fertile Crescent.
Monophyletic characteristics were attained without any human intervention, implying that apparent domestication of the cereal rachis could have occurred quite naturally. Similar ploughs were used throughout antiquity. Agriculture began independently in different parts of the globe, and included a diverse range of taxa. At least 11 separate regions of the Old and New World were involved as independent centers of origin. Domestic pigs had multiple centres of origin in Eurasia, including Europe, East Asia and Southwest Asia,  where wild boar were first domesticated about 10, years ago.
Area 3 grey is no longer recognised as a centre of origin, and Papua New Guinea red, ‘P’ was identified more recently. These eight crops occur more or less simultaneously on Pre-Pottery Neolithic B PPNB sites in the Levant , although wheat was the first to be grown and harvested on a significant scale. At around the same time BC , parthenocarpic fig trees were domesticated.

Humanity has passed through three major evolutionary phases – hunter gatherer , agricultural and technological. It is difficult to generalise on human lifestyles as adaptation to the environment is a continual, cultural and learned process. Instead of genetic adaptation, cultural adaptation has been important. Physical changes are small.
Producing food by cultivating crops and raising animals was a most important step forward in the development of human history.
Technical Information Art, science, and industry of managing the growth of plants and animals for human use. In a broad sense agriculture includes cultivation of the soil, growing and harvesting crops, breeding and raising of livestock, dairying, and forestry. Regional and national agriculture are covered in more detail in individual continent and country articles. See also separate articles on the states of Australia and the U. Modern agriculture depends heavily on engineering and technology and on the biological and physical sciences.
Irrigation , drainage , conservation, and sanitation each of which is important in successful farming-are some of the fields requiring the specialized knowledge of agricultural engineers. Agricultural chemistry deals with other vital farm problems, such as uses of fertilizer, insecticide, and fungicide, soil makeup, analysis of agricultural products, and nutritional needs of farm animals.
Plant breeding and genetics contribute immeasurably to farm productivity. Genetics has also placed livestock breeding on a scientific basis.
