Lesson 2 – Precambrian/Cambrian, Early Life, Arthropods. Evolution, Darwin

Examine the earth’s most early forms of life in the Precambrian and Cambrian periods. Spend some time on the Cambrian explosion and the Burgess Shale creatures. Introduce evolution. We may take a few weeks to cover this, as evolution is so important and the basis of modern biology. Our first scientist, Charles Darwin will be covered, his story as well as the Galapagos Islands.
