EVOLUTION & BIODIVERSITY (& Classification) Topic 5


The new IB syllabus has given this topic a boost! There is some good biology here now, as well as a twist in the end for HL, about speciation.

TOPIC 5 EVOLUTION AND BIODIVERSITY (and classification). The syllabuses:

5.1 EVIDENCE FOR EVOLUTION5.1 evidence for evolution

5.2 NATURAL SELECTION5.2 natural selection

5.3 CLASSIFICATION AND BIODIVERSITY5.3 classification and biodiversity a5.3 classification and biodiversity b

5.4 CLADISTICS5.4 cladistics


10.3 HL gene pools and speciation
