The objective of this study was to determine the genetic and environmental sources of individual differences in fear conditioning by means of a twin sample. A 2008 study of twins found that the genetic factors influencing fear at younger ages were different than the genetic factors influencing fear after puberty. "I'm not sure if anyone till now has demonstrated with data just how dangerous large snakes must have been to early hominin species in the ancient past," writes Headland, who co-authored the paper with Cornell University herpetologist Harry Greene.
