Altruism the basis of sexual selectionAbstractThe study was done to explain the human altruism of sexual selection hypothesis which wasgiven by Darwin in the year 1871. This hypothesis told that altruism is a form of mating signal,so as to know about the characteristics of opposite sex. This may increase the chance of selectionto mate. This hypothesis states that altruism is a sexually selected trait so as to increase thechances of being attracted, retain and reproduce with the other sex. For the study, variousparticipants were chosen and were asked to read the information and then were presented a seriesof images which were attractive and non-attractive. The observations were to be done in order tocheck the financial altruism or non-financial altruism and was noticed that the participants werechoosing on the basis of attractiveness. This explained the evolution of altruism whichdetermines that the people show altruism for more attractive people. The 2- D facial images andonline facial database were used for the methodology and paired sample t-test for non-financialaltruism were utilized for the experimentation or the study.The more attracted people wereassumed to give more positive attribute range than the non-attractive ones. Various studies havebeen reported for the past ten years. The whole experiment was based on the attractive and non-attractive images.IntroductionAltruism is the word coined by Auguste Comte, a French philosopher; it is derived from Latinword ‘alteri' which means ‘someone else.' In French it is termed as ‘altruisme’ which meansselflessness; used as an antonym for selfishness. Altruism is defined as welfare to others whichmay or may not harm or benefits themselves.There are many sexual selection theories which talk
about the natural selection of the living creatures on the basis of their mating patterns orattractiveness towards opposite sex. One is the reproductive success theory determines thenatural selection by measuring the fitness of offsprings and by measuring the number ofoffspring left. According to sexual propaganda theory mate was lead opportunistically, bystrength of mate signals, trophic resource, phenotypic characteristics, etc. and explained thegenetic diversity maintenance within the population. The Hola effect tells about the observer'sfeelings, overall impressions of a person on others. Darwin and Ronald Fisher gave a greatcontribution in the sexual theories by explaining that for natural selection the sexual selection isalso important and mating with the opposite partner the sperm competitiveness, physical featuresare also important factors to get attracted.The study is done to give an explanation to the sexualselection hypothesis given by Darwin in the year 1871. Altruism is known to be the matingsignal which is important to attract and influence the opposite partner for sex behavior.Thealtruism was studied non-financially and financially using DV andIV. IV was the study done onthe basis of facial attractiveness that too within the group while the DV determines the dependentvariable which can be measured by social dilemma or online dictator game. Participants wouldbe more altruisic towards facial attractiveness.MethodAn experiment was designed within the group of few people or may consider them asparticipants. Various images were pre-set into the category of attractiveness and unattractiveness;participants were allowed to rate those attractive and non-attractive images.DesignA between groups 2 x 2 MANCOVA design was adopted in which the independent variableswere attractiveness (high and low) and sex (male and female).
