Sibling competition has lasting consequences on offspring development, behaviour and fitness. However, most studies have focused on competition between same-aged broodmates or littermates. Less is known on sibling competition in species which produce one offspring at a time, like humans. I will collect behavioural data from juveniles, and use long-term data from the Tsaobis Baboon Project and the Mandrillus Project to investigate the dynamics and consequences of sibling competition in chacma baboons and in mandrills.
