26 2.3 The evolution of life Content Selection and changes in allele frequency Speciation Aspects of evolution Cambridge Pre-U Draft Learning outcomes Candidates should be able to: a) outline Darwin’s and Wallace’s observations and conclusions b) describe evolutionary patterns of divergence and adaptive radiation including the Galapagos finches as an example c) outline the mechanisms leading to evolutionary changes in allele frequency in populations including: the role of mutation in producing genetic variation; how such variations might enable organisms with particular alleles and particular phenotypes to survive better and reproduce more frequently d) describe and explain directional, stabilising and disruptive selection e) discuss what effect increased environmental stress resulting from global climate change (with increased temperatures and more extreme weather conditions) might have on habitats and organisms and thus on food chains and niche occupation f) compare current and background rates of extinction with those during past mass extinctions (students should be aware that these figures are not agreed by all scientists) g) explain the role of isolation in allopatric speciation (with particular reference to evidence from ‘ring species’) and sympatric speciation (in relation to behavioural isolation in African cichlids) h) explain the causes and effects of bacterial genetic resistance to antibiotics Practical learning outcomes Candidates should be able to: i) investigate the relationship between aspects of the environment and features of species such as banded snails (Cepaea spp.)
Cambridge Pre-U Syllabus 2.4 Classification Content The species concept Classification systems Learning outcomes Candidates should be able to: a) define the term species with reference to morphological, genetic and biochemical similarities and capability to produce fertile offspring b) explain why classification systems are used to categorise organisms c) distinguish between phylogenetic (cladistic) and phenetic classification systems and understand the general preference for phylogenetic systems d) describe the hierarchy of seven major taxonomic groups from Kingdom to species with reference to an example (e.g. Homo sapiens) e) understand the term binomial nomenclature and why Latin and Greek are used for biological nomenclature f) discuss the merits of the five kingdom and the three domain classification systems (limited to utility and phylogenetic validity) g) explain the difficulties of including viruses in classifications of organisms Practical learning outcomes Candidates should be able to: i) recognise key features of the different kingdoms from specimens, photographs and drawings ii) use dichotomous keys to identify organisms from different taxa 27
