Kin selection and polygyny: can relatedness lower the polygyny threshold?
Resource polygyny incurs costs of having to share breeding resources for female breeders. When breeding with a relative, however, such costs may be lessened by indirect fitness benefits through kin selection, while benefits from mutualistic behaviour, such as communal defence, may increase. If so, females should be less resistant to sharing a territory with a related female than with a non-rela...
متن کاملCan humans perceive their brain states?
Although the brain enables us to perceive the external world and our body, it remains unknown whether brain processes themselves can be perceived. Brain tissue does not have receptors for its own activity. However, the ability of humans to acquire self-control of brain processes indicates that the perception of these processes may also be achieved by learning. In this study patients learned to ...
متن کاملLegal Recognition of Intersex Persons; From Negative Recognition to Positive Recognition
Incontrovertibly each person’s body has an undeniable role in shaping personality and in self- definition of ego. Nowadays and based on scientific efforts, we know sex and accordingly, gender, as a spectrum in inter bodily experience. Over the long years intersex status was considered a "disorder", but recently and in the light of modern medical, psychiatric and cognitive science, "different" e...
متن کاملExperimental evidence that kin discrimination in the Seychelles warbler is based on association and not on genetic relatedness.
In cooperative breeding systems driven by kin selection, effective kin-recognition cues are important. Recognition could be achieved by the direct assessment of the genetic relatedness of individuals or by learning through association. In the Seychelles warbler, Acrocephalus sechellensis, female subordinates maximize indirect fitness by preferentially helping genetically related nestlings. Help...
متن کاملHumans can perceive heading without visual path information.
It has previously been reported that humans can determine their direction of 3D translation (heading) from the 2D velocity field of retinal motion experienced during self-motion through a rigid environment, as is done by current computational models of visual heading estimation from optic flow. However, these claims were supported by studies that used stimuli that contained low rotational flow ...
