The mechanisms associated are complex. To have any chance of understanding them, we need to look at how these organs progressed.

To get some solutions, a group of scientists led by José M. Gómez turned to evolutionary biology. Employing phylogenetic tools — solutions that reconstruct the evolutionary associations between species — they traced the origins of similar-sex actions across mammals.
This aligns with evidence from extant primates, such as bonobos and chimpanzees, which use SSSB for social bonding. The analyze demonstrates that SSSB is prevalent and infrequently evolves in social species, In particular People with complicated social buildings.
