Instructor: Frank Gregerio
Life forms on Earth are so dynamic and complex that their biology is clearly one of the great mysteries of the universe. This class will lay the foundation of what scientists believe is the history of life on Earth.
Week 1. Development of Life on Earth. How and when do we think Life began on Earth? What course of evolution did life follow over the next 4 billion years? How did our biosphere recover from five mass extinctions, with one wiping out over 95% of all living things on Earth? Are we now experiencing our sixth mass extinction?
Week 2. The cell. All life on Earth is made of microscopic cells. What is a cell? What are nuclei, DNA, ribosomes, mitochondria, Golgi Bodies and other internal organelles? What turns a single cell into a butterfly, a worm, an elephant, a human, or a giant tree?
Week 3. DNA and RNA. What exactly are they? What are genes and chromosomes? How do they reproduce so faithfully? How do DNA and RNA mutate and cause problems? What is the newly discovered “Epigenome” that may be a vital part of our cellular chemistry?
Week 4. Genetics and Inheritance. How does DNA and RNA code get translated into various tissues? What are Gregor Mendel’s principles of Inheritance and Traits? What are “dominant” and “recessive” genes? How do mutation and change shape life on Earth?
