  • 6. The Linnaeus Classification System • In 1758 Carolus Linnaeus, a Swedish botanist, created the framework for the classification system we use today. Interesting!
  • 7. Six - Kingdom System– The six-kingdom system © Current Publishing Corp. 2006 divides kingdom Monera into two kingdoms: kingdom Eubacteria and kingdom Archaebacteria.– Some people just divide living things into 5 kingdoms (uniting all bacteria) Taxa tree 5-7

Who was the scientist that really came up with the first really good classification system?8. What language are scientific names in? Where was this spoken? Quiz next time
