IB Biology Expert Presentations on Evolution (with questions)

2 Explain how polyploidy can contribute to speciation
Polyploidy is …… This helps speciation by …..

3 Compare allopatric and sympatric speciation.
Sympatric: in the same geographical area. Allopatric: in different geographical areas.

4 Outline the process of adaptive radiation.
How does this explain the evolution of structures which are similar but have a different function? Pentadactyl limbs ….

5 Compare convergent and divergent evolution.
Convergent Evolution – example = Divergent Evolution – example =
