COMMUNICATION Animals use signals to influence the behavior of other animals Social animals – those that live in groups – have many forms of communication There are different signals for different social situations The signal must be something that can be easily sent and received

PRIMATE COMMUNICATION V ocal communication is most developed in primates Many have different sounds (‘words’) for different predators Human language development begins at an early age – a child learns the language it hears spoken Other forms of communication – body language – are also important

REPRODUCTIVE BEHAVIOR Each species has a unique courtship signal – prevents mating with the wrong species Mate choice – in most animals the female evaluates a mate before choosing The female has a higher ‘stake’ in the choice – more energy to have babies & care for them Sexual selection – the mate is chosen based on a certain trait – fancy tail feathers in male birds In some species the males compete with each other – often to select the strongest
