Aggressiveness of martial artists correlates with reduced temporal pole grey matter concentration

From an evolutionary point of view, aggressive behaviour is a widespread phenomenon in animals and humans (Kr ämer et al., 2011; Pietrini and Bambini, 2009). Violence against the own species occurs in almost all mammals (Gómez et al., 2016; Porges and Decety, 2013). Lorenz (1963) has explained this remarkable abundance by reproductive advantages for more aggressive individuals and their aggression disposi ng genes. This kind of behaviour is a prerequisite for building and dominating hierarchies, which goes along with power and higher reproductive success (Elbert et al., 2010).
