When I first started teaching the Diploma, my Head of Science at the time, enthused about Option D – Evolution unit as THE biology unit that best embodies the philosophy of the IBO (and I believe him to be right), encapsulating the notion of commonality of all, sharing the same common ancestors.
I continued to teach option D for 18 years, and was therefore disappointed to find that the unit has now been broken up and sections removed. No more Human evolution, no more Hardy-Weinberg equation.
I therefore thought I would use this entry to share my resources on the Option
D1 Origin of life on Earth
Video that runs through a plausible theory for the origin of the genetic code
Video on Hydrothermal Vents –
Video – Origin of life made easy
Video Miller -Urey summary But remember this was later discredited as the Earth was shown to contain CO2 in its early years, which was absent from the Miller-Urey experiment
D2 Species and Speciation
Video Natural selection made easy
Video on the finches of the Galapagos
Sex and the gubby simulation from the PBS
Peppered Moth simulation website
D3 Human evolution
Lets start with a neat simulation which I have used to teach radioactive dating.
And regarding HUman evolution, I will leave you with the following;
I will complete my sharing of resources in my next post.
