Same-sex sexual behaviour in crickets: understanding the paradox
http://dx.doi.org/10.1016/j.anbehav.2016.01.022 0003-3472/© 2016 The Association for the Study of A Same-sex sexual behaviour (SSSB) occurs in animals ranging from insects to mammals, yet its evolutionary origins remain enigmatic. Is it adaptive, or has it evolved as a by-product of selection for other traits? Using data from two experiments on male spring field crickets, Gryllus veletis, we te...
متن کاملSame-sex sexual behaviour as a dominance display
http://dx.doi.org/10.1016/j.anbehav.2016.01.005 0003-3472/ Crown Copyright © 2016 Published on be license (http://creativecommons.org/licenses/by/4.0/). Same-sex sexual behaviour (SSB) is widespread across taxa. One adaptive hypothesis to explain the occurrence and maintenance of SSB is that it acts to intensify or diminish aggression by providing males with a means to reinforce or resolve domi...
متن کاملTesting for competence rather than for "intelligence".
The testing movement in the United States has been a success, if one judges success by the usual American criteria of size, influence, and profitability. Intelligence and aptitude tests are used nearly everywhere by schools, colleges, and employers. It is a sign of backwardness not to have test scores in the school records of children. The Educational Testing Service alone employs about 2,000 p...
متن کاملA test of genetic models for the evolutionary maintenance of same-sex sexual behaviour.
The evolutionary maintenance of same-sex sexual behaviour (SSB) has received increasing attention because it is perceived to be an evolutionary paradox. The genetic basis of SSB is almost wholly unknown in non-human animals, though this is key to understanding its persistence. Recent theoretical work has yielded broadly applicable predictions centred on two genetic models for SSB: overdominance...
متن کاملSame-sex sexual behavior and evolution.
Same-sex sexual behavior has been extensively documented in non-human animals. Here we review the contexts in which it has been studied, focusing on case studies that have tested both adaptive and non-adaptive explanations for the persistence of same-sex sexual behavior. Researchers have begun to make headway unraveling possible evolutionary origins of these behaviors and reasons for their main...
