    Peruvians Select Genitically Superior Potatoes

    Peruvians Select Genitically Superior Potatoes
    From around 160 species of wild potatoes Peruvians plant the species with the lowest level of poisons and grow them for food.

    The Start of Agriculture

    People started planting their own food. They planted their food because of harsh weather and the bred animals so they didn't have to hunt. They would plant seeds close to shelters for easy access.
  • Sep 10, 900

    Preservation

    People could now grow their own food. Now there is a need to preserve the food. In the earlies years this was done by storing the food in cold caves.
  • Sep 10, 950

    Yeasts

    Yeasts have been used for human benefit for a very long time. They are used to make breads, alcohol, and alcoholic beverages. When the yeast ferments it creates alcohol.

    Cheese

    Cheese was made. This can be considered the earliest form of biotech because it takes renin from cows and adding it to milk.

    Anibiotics

    The first antibiotics appeared in China. They were soybean curds and they were used to cure boils.

    Cross-Breeding

    Cross-Breeding
    The earliest form of cross breeding can be shown when humans cross bred male donkeys and female horses creating a mule. Mules were the best of both worlds, strong and good endurance. They revolutionized transportation and transportation of goods.
  • Microbes in Detail

    Anton Van Leeuwenhoek, a Dutch tradesmand and skilled lens maker, is the first to describe microbes in detail.
  • Small Pox Vaccine

    English surgeon Edward Jenner was first to make the vaccine. He first inoculated a child with a viral smallpox vaccine. This was the first time someone had been inoculated by this vaccine.
  • Mendell Pea Plant Discovery

    Mendell Pea Plant Discovery
    Mendell discovers that through selective breeding, traits can be passed down from plants and animals. He does this by breeding pea plants and observing the different characteristics of each plant.
  • Discovery of Fungus Colonies on Gelatin

    Oscar Brefeld reports the growth of fungal colonies from single spores on gelatin. The German botanist Joseph Schroeter grows pigmented bacterial colonies on slices of potatoe.
  • Bacillus

    Ferdinand Julius Cohn publishes landmark paper on bacteria and the cycling of elements and it is an early classification scheme that uses the name bacillus.
  • Staining, Photographing, and Preparing Bacteria Slides

    Robert Koch develops methods for staining bacteria, photographing, and preparing permanent visual records on slides.
  • Pure Cultures of Bacteria

    Koch develops solid culture media and the methods for obtaining pure cultures of bacteria.
  • Discovery of Agar in Preservation

    Angelina Fannie and Walther Hesse in Koch's lab devolop the use of agar as a support medium for solid culture.
  • Indentifying Bacteria System

    Hans Christian Gram develops a disystem for developing bacteria. This identification method is known as the Gram Stain.
  • First Report of the Petri Plate

    In 1887, Julius R Petri invented and publicized the use of a plate of bacteria for scientific research.
  • Quantitave Approach for Analyzing Water

    M H McCrady establishes a quantitative approach for analyzing water samples. He does this by using the most probable number and multiple tube for fermentation test.
  • Mystery of DNA Solved

    Mystery of DNA Solved
    Watson and Crick discovered the double helix structure of DNA. They announced it in Belgium on April 8th. They were awarded the Nobel Prize of Physiology or Medicine on their study of nucleic acids.
  • Understanding of Genes

    The understanding of genes and how they work deepens.
  • GMO Development

    GM soybeans and corn are officially allowed to be sold in US. GM cotton is commercialized in the US. GM crops become the most rapidly adopted technology in the history of agriculture.
  • The Green Revolution

    Scientists work on creating a high yeild varieties of types of grain, wheat, corn, millet, and rice. This massively increases the production of crops in coutries and it is said to be the green revolution. Creation of the dwarf wheat increases 70%.
  • Concept of Operon

    Jacob and Monad introduce the Operon concept. An operon is a cluster of bacterial genes that helps to control the transcription of other genes using mRNA.
  • Synthesizing DNA

    For the first time Dr. Hargobind Khorana synthesized DNA in a test tube. He won the Nobel Prize for Physiology or Medicine for his work with nucleotides and nucleic acids.
  • Cytoplasmic Hybridization

    Kohler and Milestein created cytoplasmic hybridization. They produced the first monoclonal antibodies which revolutionized diagnostics.
  • Multiplying DNA

    Karl Murris was able to harness DNA in a test tube and amplify the DNA. He was able to make thousands of strands of DNA in a test tube.
  • Chymosin and the Development of GMOs.

    Scientists create chymosin to help in the making of hard cheese. China is now starting to sell GMO foods, mainly VR tobacco and tomatoes.
  • Golden Rice

    German and Swiss scientists develop golden rice, fortified with betacarotene, which stimulates production of Vitamin A that can prevent some forms of blindness.
  • Entire Plant Genome is Sequenced

    The first entire plant genome is sequenced, Arabidopsis thaliana, which provides researchers with greater insight into the genes that control specific traits in many other agricultural plants.
  • Tomato Farming Advancement

    Tomato Farming Advancement
    U.S. and Canadian scientists develop a transgenic tomato that thrives in salty conditions, a discovery with the potential to create tomatoes and other crops that can grow in marginal conditions.
  • GMO Revolutionizes Farming

    GMO Revolutionizes Farming
    The National Center for Food and Agricultural Policy (NCFAP) study found that six GM crops planted in the United States - soybeans, corn, cotton, papaya, squash and canola- produced an additional 4 billion pounds of food and fiber on the same acreage, improved farm income by $1.5 billion and reduced pesticide use by 46 million pounds.
