However, some think it may help  diffuse  confrontation or foster intimacy by revealing weakness. 2 – Laughter: mood-improving endorphins are released when we  laugh, which seems  an obvious reason to do it but a 10-year study muddied the waters when  it found  more laughter is produced by banal comments than jokes. 3 – Kissing: the explanation for kissing is unlikely to be  genetic as not all  human societies do it. There are theories that it is associated with  memories of  breastfeeding and that ancient humans weaned their children by feeding  them from  their mouths, which reinforced the link between sharing saliva and  pleasure. 4 – Dreaming: Sigmund Freud’s theory of dreams expressing our  subconscious  desires have been generally discredited and it is recognised that they  help us  process emotions, but the reason why we see such strange visions has not  been  properly explained. 5 – Superstition: unusual but reassuring habits make no  evolutionary sense;  however, ancient humans would have benefited from not dismissing a  lion’s rustle  in the grass as a gust of wind. Religion seems to tap into this impulse. 6 – Picking your nose: the unappealing but common habit of  ingesting ‘nasal  detritus’ offers almost no nutritional benefit, so why do a quarter of  teenagers  do it, on average four times a day? Some think it boosts the immune  system. 7 – Adolescence: no other animal undergoes the stroppy,  unpredictable teenage  years. Some suggest it helps our large brain reorganise itself before  adulthood  or that it allows experimentation in behaviour before the responsibility  of  later years. 8 – Altruism: giving things away with no certain return is odd  behaviour in  evolutionary terms. It may help with group bonding or simply give  pleasure. 9 – Art: painting, dance, sculpture and music could all be the  human equivalent  of a peacock’s tail in showing what a good potential mate someone is.  However,  it could also be a tool for spreading knowledge or sharing experience. 10 – Body hair: fine hair on the body and thick hair on the  genitals is the  opposite of what occurs in primates, our close animal relatives.  Suggested  reasons for pubic hair include a role in radiating scent, providing  warmth or  even protecting from chafing.
