Its invention led to the development of many other machines that helped replace animalpowered carts and plows. Most of this new technology was powered by burning coal that ran steam engines. C. However, it was not used to run machinery until the late 1600s. Steam-driven tractors were introduced in 1750 and were common by 1904. E. Lenoir in 1860. Gasoline-engine tractors and farm equipment replaced steamdriven machinery by the 1920s. 4). Energy from fossil fuels also aided transportation and food processing.

The ancestoral plants usually produced smaller and fewer edible parts. Corn grown today produces many larger kernels Gregor Mendel and Selective Breeding Little was known about the inheritance of traits before the research of Czechoslovakian monk Gregor Mendel was rediscovered in 1900 by Carl Correns in Germany, Hugo de Vries in the Netherlands, and Erich von Tschermak-Seysenegg in Austria. William Bateson coined the term “genetics” to explain the study of inheritance. From 1857 to 1865, Mendel performed experiments with the pea plant showing that traits were inherited in predictable patterns.

Agricultural biotechnology makes use of these molecules to make consumer products or to improve animals and crops. 7 8 BIOTECHNOLOGY ON THE FARM AND IN THE FACTORY (continued from page 5) sheets of a protein called keratin. Proteins called enzymes carry out a variety of jobs for cells. Their main job is to perform the chemical reactions that run an organism’s metabolism. Enzymes have thousands of uses in everyday life. They are commonly used in making certain foods and household substances. Proteins called antibodies fight disease and others called storage proteins act as reserves for amino acids.
