Assessment statements

DCS Topic Code Statement Guidance
A.6.A1 Migratory behaviour in blackcaps as an example of the genetic basis of behaviour and its change by natural selection. The seven applications in this sub-topic are intended to reinforce understanding of the general principles. The applications include a range of types of behaviour and types of animal. Other examples, including local examples that can be observed, should also be studied if possible.
A.6.A2 Blood sharing in vampire bats as an example of the development of altruistic behaviour by natural selection.  
A.6.A3 Foraging behaviour in shore crabs as an example of increasing chances of survival by optimal prey choice.  
A.6.A4 Breeding strategies in coho salmon populations as an example of behaviour affecting chances of survival and reproduction.  
A.6.A5 Courtship in birds of paradise as an example of mate selection.  
A.6.A6 Synchronized oestrus in female lions in a pride as an example of innate behaviour that increases the chances of survival and reproduction of offspring.  
A.6.A7 Feeding on cream from milk bottles in blue tits as an example of the development and loss of learned behaviour.  
A.6.U1 Ethology is the study of animal behaviour in natural conditions.  
A.6.U2 Natural selection can change the frequency of observed animal behaviour.  
A.6.U3 Behaviour that increases the chances of survival and reproduction will become more prevalent in a population.  
A.6.U4 Learned behaviour can spread through a population or be lost from it more rapidly than innate behaviour.
