Early farmers picked up some fruit of wild plants to home, eat them, and spited out the bigger seeds or defecated the tiny size seeds to human latrines. And then the seeds germinated in the early lab. But the key points were how the early farmers decided to pick up which fruit? It’s not hard to make some hypothesis:
Fruit size:
Strawberry, early farmers went into thorny thicket amid the mosquitoes on a hot, humid day to pick up strawberry; the only criterion is the size. The early farmer would choose only bigger size ones to compensate the while to get sunburned and mosquito bitten.
Bitterness:
Many wild seeds evolved to be bitter, bad-tasting or even poisonous to keep human or animals away from eating them. Natural selection functioned as getting the fruit tasteful dispersed by animals and continue the process of reproducing, meanwhile if the seed remained tasteful, the animal will chew them up as well.
Occasional individual almond trees have a mutation in a single gene that prevents them from synthesizing the bitter-tasting amygdalin, which breaks down to yield poison cyanide. Such trees die out in the wild, while the trees lived near humans survived by being picked up by curious children or early farmers who noticed the non-bitter fruit.
Fleshiness, Oiliness and fiber length are all similar in the selection process.
Initially the wild fruit had less fruit around their seeds, but early farmers chose the fruit mutated to be with more Fleshiness, less seeds, such as squashes, pumpkins, bananas oranges, grapes, watermelons.
Olives were cultivated earliest around 4000 B.C. Ancient farmers also selected sesame, mustard, poppies and flax for oily seeds. Modern plant scientists have done the same for sunflower, safflower, and cotton.
Before recent development of cotton for oil, it was for its fibers, used to weave textiles. Flax, hemp.

Early Mesopotamia

...The discovery of ancient cave paintings and handcrafted tools that were produced over long periods of times and spanned across vast areas, demonstrated that the ideas and skills of early peoples were purposefully passed down within their societies. These “socially transmitted patterns of action and expression” (Bulliet 11) constituted their culture. Each generation is taught by their elders, as their culture, including the fabrication of material items such as clothing, shelters, and tools is communicated along with moral values, languages, and religious beliefs. The Stone Age refers to the period about 2.6 million years ago when the first crafted stone tools appeared, to about four thousand years ago when metal tools surfaced. Although coined the Stone Age, tools were also made of less useful materials than stone including wood, bone and skin. The Stone Age is broken up into two phases. The Paleolithic phase or Old Stone Age is characterized by hunters and gatherers who built temporary shelters, or found natural places of refuge. Increased meat eating was brought about by making tools such as the hand ax and spear. Men did most of the hunting, while women’s roles included gathering plants and vegetables. The need of human babies for longer maturation resulted in the imperative need for parental care by their parents. Extensive knowledge of their environment was crucial for survival, they had to learn how to adapt and use resources to make clothing and other materials.......

The Civilizing Process and the Domestication of Fire

...The Civilizing Process and the Domestication of Fire* johan goudsblom University of Amsterdam In the two volumes of The Civilizing Process (first published in German in 1939, and in English in 1982) Norbert Elias studied changes in manners, society, and personality in western Europe over the period roughly from 850 to 1850. The documentary evidence upon which he based his argument was mainly derived from the second half of this period, from 1350 to 1850. The purpose of the study was to arrive at a better understanding of the contemporary world, and of its social and psychological problems.1 Now, by any conventional standards the period from 1350 to 1850, not to speak of the millennium from 850 to 1850, is a very long time. Yet, when we take into account the full history of human civilization, it is short: an episode, no more. Consequently, since Elias’s focus was upon the changes that have taken place in western Europe since 1350, certain underlying patterns in human history had to remain in the background. Elias himself was aware of this, and in later writings he 1 Journal of World History, Vol. 3, No. 1 © 1992 by University of Hawai‘i Press *This is the slightly abridged text of the first Norbert Elias lecture, delivered at the University of Leicester on 6 March 1991. 1 For further information on the book and its background, see Stephen Mennel, Norbert Elias: Civilization and the Human Self-Image (Oxford: Basil Blackwell, 1989).

...many different types of plants on the planet earth, but one that stands out to me is the eucalyptus tree. Growing up as a kid, I always wondered how a plant could grow so tall towering over everything else and lasting for years and years through severe weather changes. Eucalyptus is flowering tree with several different types of species. The name is actually derived from the Greek word “eucalyptos,” which means “well covered,” and refers to the cuplike membrane that covers the budding flowers of the tree.2 They are mostly found in the continent of Australia, and few parts in Africa as well. The wood from eucalyptus trees are very hard and they are used to make furniture, fences, canoe boats and picture frames. These trees can grow really tall usually over 80 meters in height towering into the sky with wide spread leaves. Because of its large geographic range the genus exhibits many habits, from tall trees to multistemmed, shrubby species called mallees. The mountain ash (Eucalyptus regnans) of Victoria and Tasmania is the tallest hardwood in the world, reaching heights over 330 ft (100 m); only the coast redwoods of California are taller. Having epicormic buds in branches and stems, and lignotubers in the roots, many species are well adapted for surviving fire and drought. Some species have smooth bark, in which case they are referred to as gum-barked, while others have rough bark.1 To begin, the scientific name for the eucalyptus plant is Eucalyptus......

Domestication designates the type of translation in which a transparent, fluent style is adopted to minimize the strangeness of the foreign text for target language readers; while foreignization means a target text is produced which deliberately breaks target conventions by retaining something of the foreignness of the original. In the contemporary international translation field, E ugene Nida is regarded as the representative of those who favour domesticating translation, whereas the Italian scholar L aw rence Venuti is regarded to be the spokesman for those who favour foreignizing translation, who has also led the debate to a white-hot state.

Early Civilazations

... Early Civilizations From 10200 B.C to 400 AD was a timeline of Early Civilizations. Early Civilizations are divided into 3 main groups; The Neolithic Era, Bronze Age and Iron Age. They all had great accomplishments in agriculture, government, religion, and education. Every civilization had their own unique way of living. Many of our agriculture, inventions, and religion were practiced by them. We merely adopted their way of life. So we can say that Early Civilizations became fundamentals for our modern invention, agriculture and religion. Ancient people discovered the development of agriculture accidentally. Before finding agriculture, ancient people had a hunter-gatherer system where males go hunting and females and kids stay home and gather fruits or any other edible plants. Farming started from the Neolithic Era which involved the domestication of animals and plants. Increasing population was the number one reason people started to farm. Because they couldn’t feed all the hungry mouths just by hunting animals. They had to have a large population at that time because ancient people lived under constant dangers caused by other tribes. The people who first cultivated cereal grains have observed them in the wild while they were hunting or gathering and noticed the seeds fall. After sometime, they return to the same place to find a newly grown plant. That’s when they got the idea of farming. 2 best......

...Hikemeister, While I can’t turn you into a hot botanist, I can explain how C3 and C4 plants are different and suggest how their distribution might be expected to change with altitude. As I will best try to become your “Plants for Dummys” guide as it is crucial that you first have an understanding of the difference between C3 and C4 plants, to even remotely fool your plant lady guru. Firstly, the difference between C3 and C4 plants is that C3 plants form a pair of 3 carbon-atom molecules during CO2 assimilation while C4plants, which account for an abundance on higher regions of the mountain, form 4 carbon-atom molecules. By far the most important difference for rising CO2 levels is that C3 species continue to increase photosynthesis with rising CO2 while C4 does not. As you climb up the mountain, as I’m sure you noticed, the air becomes very dry and thin all due to the change in altitude. This is due to the enzyme used in C4 plants to convert CO2 into organic molecules known as PEP carboxylase, which has a high affinity only for CO2 - making it easier at fixing CO2 than C3 plants. Ultimately, this means that C4 plants don’t have to keep their stomata open as long as C3 plants in order to produce the exact same number of CO2 molecules, which are used to make ATP and glucose in the Calvin Cycle. As a result, as water loss is reduced, C4 plants become a much better fit to arid the “Three Sisters” of Alberta. Hope this peaks both your......

...Inquiry Research Paper Every plant is different. There are no two plants that are the same, nor are there two that grow the same way. Some plants grow in hot, dry environments while others grow in cold, damp environments. Some plants grow in the tropical rain forests while others grow in prairies. Even plants that are in the same family can grow in different climates and environments. Plants can be as similar as they are different. Plants need certain factors to be able to thrive in an environment. They need certain levels of water and sunlight. They need a certain type of soil and certain amount of shade. Plants are very picky on how, when and where they grow. The Beavertail Cactus, African Lilly, and Boston fern are three plants that are very different in many ways. They all grow in different regions and require different levels of abiotic factors. They are each unique in their own way and are ever different then the species in their families. The Beavertail Cactus is a part of the cactaceae, cactus family. It has a scientific name of Opuntia basilaris. The cactus is the state cactus of Texas. The lifespan of it is over twenty years. Another name that the Beavertail Cactus is referred to is “Prickly Pear.” It is referred by that name because of the fruit that grows on it. Spanish-American culture influenced a nickname for the fruit, “tuna.” The Beavertail Cactus is flat and pancake like with no leafs. It is a dull green color. The cactus can reach up to seven......

...into the 20th century, species were divided into two kingdoms: animals and plants. Driven by DNA characterizations and other modern analysis, fungi and bacteria have now been removed to separate kingdoms; in particular, fungi have cell walls that contain chitin rather than cellulose. Lichens, which are a symbiotic association of a fungal and photosynthetic organism, are generally not considered plants in the purest sense of taxonomy, although earlier classification schemes viewed them as plants. Viruses are also not considered to be plants, since they do not have a cell of their own, but inhabit a host cell of another organism; moreover, in many classifications they are not considered a living organism at all. Myxomycetes, or slime molds, are also not considered plants, but rather are heterotrophs that can ingest bacteria, fungal spores, and other items. The scientific study of plants, known as botany, has identified about 350,000 extant taxa of plants, defined as seed plants, bryophytes, ferns and fern allies. As of 2008, approximately 400,000 plant species have been described,[2] of which roughly ninety percent are flowering plants. Vascular plants have lignified tissue and specialized structures termed xylem and phloem, which transport water, minerals, and nutrients upward from the roots and return sugars and other photosynthetic products. Vascular plants include ferns, club mosses, flowering plants, conifers and other gymnosperms. A scientific name for this......

Domestication and Classification of Non Ruminants

...Introduction Domestication is the process of adapting wild plants and animals for human use in which individual species have been altered to create breeds with characteristics more desirable to human needs. Some of our earliest evidence of man (and art) is tied to animals. Dogs were the first species of animals to be domesticated due to security. SWINE  BRIEF HISTORYOF DOMESTICATION All Pigs were descended from the European wild boar as early as 13,000 BC. And the Local breeds were introduced to African countries by the colonists DISTRIBUTION OF PIGS ACROSS THE WORLD The distribution of pigs around the world is not the same. Almost half the exotic world’s pig population is in Asia (China) 30 per cent in Europe and the former USSR. The population of pigs in large parts of the tropical and sub-tropical developing regions for example Africa and Latin America is relatively small. Local breeds are widely distributed in west- African countries ( Ghana and Nigeria). A typical example of local breeds is the Ashanti dwarf pig or Nigerian hairy black pig. CLASSIFICATION OF PIGS  Generally, Pigs can be classified as; 1. Classification Based On functionality: Meat Type: They are meaty pigs with little fats e.g Berkshire, Chester white Duroc, Hampshire. Lard Type: These are small lardy pigs (composed of high percentage of fats). Bacon Type: They build sufficient muscles for desirable bacon (meat from the sides, belly, or back of a pig).......

Describe the Evolutionary Developments That Enabled the Successful Colonisation of Terrestrial Habitat by the Early Plants

...Question Describe the evolutionary developments that enabled the successful colonisation of terrestrial habitat by the early plant? Plants evolved from an aquatic algal ancestor during the Devonian period. The transition from water to land had some useful advantages. Land provided a good substrate with nutrient rich soils and there were no predators in form of herbivores and microbes. Carbon dioxide concentration in air was very high and readily diffuses in plants than when dissolved in water. Sunlight levels in air were very high and these conditions favoured photosynthesis (Raven et al, 1992). However life on land presented challenges that led to morphological adaptations and to the subsequent evolution of present day plants. Life on earth presented problems of acquisition and distribution of nutrients, preservation of water support and reproduction. The earliest evolutionary adaptation was multicellularity, differentiation and specialisation of structures. The plants evolved an aerial structure that is photosynthetic and functions in gaseous exchange. They also developed an anchorage to the substratum, soil. Meristems evolved and provided the much needed cells that differentiated and specialised into useful structures (Campbell and Reece, 2005). In bryophytes the cells differentiated into rhizoids, antheridia and archegonia, setae and capsule. In Pteridophytes they developed into xylem and phloem, fronds, roots and root hairs (Solomon et al, 2012). This......

...Plants, also called green plants, are multicellular eukaryotes of the kingdom Plantae. They form an unranked clade Viridiplantae(Latin for green plants) that includes the flowering plants, conifers and other gymnosperms, ferns, clubmosses, hornworts, liverworts,mosses and the green algae. Green plants excludes the red and brown algae, the fungi, archaea, bacteria and animals. Green plants have cell walls with cellulose and obtain most of their energy from sunlight via photosynthesis by primary chloroplasts, derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic and have lost the ability to produce normal amounts of chlorophyll or to photosynthesize. Plants are also characterized by sexual reproduction, modular[clarification needed] and indeterminate growth, and an alternation of generations, althoughasexual reproduction is also common. Precise numbers are difficult to determine, but as of 2010, there are thought to be 300–315 thousand species of plants, of which the great majority, some 260–290 thousand, are seed plants (see the table below).[1] Green plants provide most of the world's molecular oxygen[2] and are the basis of most of the earth's ecologies, especially on land. Plants that produce grains, fruits and vegetables form mankind's basic foodstuffs, and have been domesticated for millennia. Plants are used as ornaments and, until recently and in great variety, they...

...Plants are vital to the survival of all life on Earth--plants transform the light of the sun into energy that is usable to other life on Earth. Without plants, animals would not be able to use the energy of the Sun that reaches the Earth. The removal of one plant from the ecosystem can cause many unforeseen changes, sometimes irreversibly damaging an ecosystem. However, some plants are more important than others, either for biological or cultural reasons. In my country, Korea, I would say that the grass that produces rice has come to be the most important plant, not just because rice is a staple food, but also for other cultural reasons. Virtually every Korean eats rice at least twice a day. I, for example, had rice at breakfast, lunch, and dinner yesterday. For most Koreans, rice is an integral part of a meal, as expected in a meal as ink is to a pen or wheels are to a car--a meal without rice is not a meal. In fact, if I have dinner with my American friends and do not eat rice, I actually feel hungry even if I have filled myself with potatoes or other food while eating with them. Many of my friends have made similar comments to me. So, I believe that rice is as much a part of our daily lives as work or talking on the telephone is. However, rice is much more than just a staple food to most Koreans--it represents the very sustenance of much of our culture. Our history teachers tell us that the development of rice as an agricultural product was largely responsible for the......

...evolutionary relationships among organisms and the diversity of life on earth. Biological science is classified into various branches, which depend upon the organisms to be studied. These are some main branches of biology Botany, Entomology, Ecology, Anatomy, Immunology, Limnology, Genetics, Histology, Biomechanics and Embryology. The study of plant life or phytology is known as botany. It's studies the life and development of fungi, algae and plants. Botany also probes into the structure growth, diseases, chemical and physical properties of the plant species. Also it implies the importance of study of plant life on earth because they generated food, fibers, medicines, fuel and oxygen. A person who is working in the study of botany is called a botanist. As a botanist, you study plants and apply you knowledge to teaching and research in agriculture, horticulture, and land use planning and medicine. Usually they investigate the effects of environmental factors such as rainfall, temperature and disease on plant growth, they grow plants under controlled conditions to assess the significance of environmental variables and prepare handbooks for plant identification. Entomology is the study of insects. Insects are one of the most successful and diverse groups of living organisms in world today. It concentrates on studying the taxonomy, features, adaptations, roles and behavior of insects. If you're interested about insects and their behavior you might consider yourself to be an......
