  1. AG 10.01 • Describe methods of plant and animal improvement as a result of biotechnology.

  2. Great Truths • 4,000 BC The moon is eaten once each month by a large invisible beast • The moon darkens each month because the angle between the Earth, Moon and Sun changes

  3. Great Truths • 1400 AD Diseases are caused by evil spirits that inhabit a body • Diseases are caused by microscopic agents • 1500 Flies develop spontaneously from rotten meat • Flies lay their eggs in rotten meant and hatch

  4. Great Truths • 1600 The brain pumps fluid into the muscles to make them bulge and contract • The brain contracts muscles using tiny electrical and chemical signals • 1800 Tyrannosaurus Rex walked vertically and dragged its tail • T-Rex leaned forward and its tail balanced it, but it didn’t touch the ground

  5. Great Truths • 1850 The planet Mars is covered with canals that could only be made by intelligent life • Mars is covered by icy cracks that were once rivers • 1900 The Apatosaurus and brontosaurus are two different dinosaurs. • They are the same species

  6. Great Truths • 1970 Saturn is the only plant with rings around it • Uranus and Jupiter also have rings • 1980 Eating eggs makes your cholesterol levels rise • Some people’s cholesterol levels stay the same or go down even if they eat eggs

  10. The Beginnings of Biotechnology • 1953 Watson and Crick reveal the three-dimensional structure of DNA • 1970 Dr. Norman Borlaug wins the Nobel Price for Peace • 1973 Cohen and Boyer perform the first successful recombinant DNA experiment.
