    Genetically Modified Foods

    GM plants were first marketed in the 1990s. The first commercialized GM crop was a TOMATO called Flavr Savr (resistant to rotting), marketed in 1994 by a US-based company, Calgene. Since then, many GM crops have been commercialized.

    Genetics

    Genetics is that subdiscipline of biology devoted to the study of heredity, the phenomenon by which organisms pass on their characteristics to their offspring. Although humankind has always shown an interest in heredity, the practice of the science is usually considered to have begun in 1865 with Gregor Mendel, an Austrian monk. Through a study of pea plants, Mendel worked out the simple patterns of inheritance that apply to most inheritable characteristics of living things (e.g., size, shape, colour, hairiness, smell, behaviour, disease resistance). Mendel formulated the concept of the gene to define the fundamental units of heredity that determine such properties. Today the molecular structure and function of genes is quite well understood.

    Geomorphology

    Geomorphology is primarily concerned with the scientific study of landscapes and landforms on Earth's surface, and the processes acting on them, although geomorphic principles are also applied to the study of planetary bodies with solid crusts, such as the Moon and Mars. Geomorphologists seek to explain variations in surface form and evolution and the impact of geomorphological processes on human populations, including hazardous events such as landslides and river flooding, which may intensify in the future with climate change. Modern geomorphologists usually align themselves with a specialized branch of the subject, such as glaciers, rivers or coasts. In Canada, which was covered by several large ice sheets and still has permafrost underlying half its land mass, many geomorphologists are concerned with the Quaternary (last 2.6 million years) or with prevailing cold conditions.

    Grain Elevators

    Grain elevators, which have been variously referred to as prairie icons, prairie cathedrals or prairie sentinels, are a visual symbol of western Canada. Numbering as many as 5,758 in 1933, elevators have dominated the prairie landscape for more than a century with every hamlet, village and town boasting its row of them, a declaration of a community's economic viability and a region's agricultural strength.
