This week in grade 11 biology we started to study topic 5: Evolution. We discussed the differences between facts and theories bringing in some thoughts from the Theory of knowledge coutse. We understood that theories are based on a vast amount of evidence and are our best scientific explanation for the real world phenomena we experience everyday. The students then researched the evidence from anatomy (homologous structures), paleontology (fossils), molecular biology (similarities between proteins and the universality of the genetic code), embryology and many other fields of biology. This topics recommended reading for students that want to learn more about the comprehensive evidence for evolution is Richard Dawkin’s The Greatest Show on Earth.
