Homosexual Behavior in Female hill Gorillas: expression of Dominance, Affiliation, Reconciliation or Arousal?

Right right right Here we offer initial formal report of homosexual behavior in female gorillas/mountain gorillas.

We also make an effort to test three of the very often invoked hypotheses in connection with practical need for this pattern plus a extra theory. Offered the notably restricted range findings and partial not enough critical information to evaluate contending hypotheses, it is considered a pilot undertaking. 1) The reconciliation hypothesis proposes that vaginal contacts are designed for resolving disputes [7, 20]. This theory happens to be analyzed in bonobos and Hanuman langurs, with blended outcomes. Hohmann and Fruth [21] discovered that vaginal connections among female bonobos failed to take place in combination with agonistic incidents, but prices rose during post-aggression stages. The job of Sommer et al. [22] didn’t accrue any findings meant for this concept.

For the study that is present proof and only the reconciliation theory will be shown if homosexual behavior is closely preceded by agonistic interactions. 2) in accordance with the bond that is social, homosexual behavior functions as a way of expressing or strengthening affiliative bonds [23]. Previous data weren’t or just partly in agreement with this specific theory ([6, 21, 22], but see[24]).
