The primitively social behavior of Euglossa cordata (Hymenoptera, Apidae, Euglossini): a view from the perspective of kin selection theory and models of reproductive skew.
The evolution of social behavior is perhaps one of the most controversial topics of biology, since the emergence of such behavior implies the evolution of altruistic traits that reduce the chance of reproduction (fitness) of individuals, through Natural Selection ( Freeman & Herron, 2009). Currently, there are models that link outputs for this apparent paradox, being the "Kinship Selection Theory" or "Theory of Fitness Inclusive", proposed by Hamilton (1964), which produced the greatest scientific impact (Queller & Strassmann, 1998; Keller & Chapuisat, 1999; Strassmann et al, 2011;. Liao, Rong & Queller, 2015).
According of Kin Selection Theory, the evolution of altruistic behavior, such as the reproductive division of labor, is associated with the genetic relatedness among group members. By granting reproductive opportunities for related individuals can obtain reproductive success. As related individuals share alleles by descent when an individual help your relative to reproduce, he's going through …show more content…
In this scenario, the bees of Euglossini tribe have been considered excellent material for such studies (ZUCCHI et al, 1969; DRESSLER 1982; Garofalo, 1994; Ramirez et al., 2002; CAMERON; RAMIREZ., 2001; Soucy et al, 2003; CAMERON, 2004; Garofalo, 2006; AUGUSTO; Garofalo, 2004, 2009 and 2011) because they are the only clearly not eusocial bees between the monophyletic group known as the group of corbiculate bees. This group is formed by Apini tribes, Meliponi and Bombini, beyond Euglossini tribe. All species of Apini and Meliponini are highly eusocial, while species Bombini are primitively eusocial (MICHENER,
