3.2 Natural selection

Students should:
$i Understand how evolution can come about through natural selection acting on variation bringing about adaptations. ii Understand how organisms occupy niches according to physiological, behavioural and anatomical adaptations. iii Understand how reproductive isolation can lead to allopatric and sympatric speciation. iv Understand that there is an evolutionary race between pathogens and the development of medicines to treat the diseases they cause.$
