But given that other research has linked the same 7R variant to far riskier behaviours, such as addiction, a short temper and delinquent behaviour, the irrepressible impulse to go interrailing seems like the better end of the Darwinistic deal.
由於有些研究將更具威脅性的行為與 7R 變異基因做連結,例如成癮行為、脾氣暴躁和違法行為,無法抑制的冒險衝動算是達爾文演化論中較好的特質。
