Altruism the basis of sexual selectionAbstract The study was done to explain the human altruism of sexual selection hypothesis which was given by Darwin in the year 1871 (Bhogal, M. S., Galbraith, N., & Manktelow, K. (2016). This hypothesis told that altruism is a form of mating signal, so as to know about the characteristics ofopposite sex. This may increase the chance of selection to mate. This hypothesis states that altruism is a sexually selected trait so as to increase the chances of being attracted, retain and reproduce with the other sex (Kotlikoff, L. J., 2016). For the study, various participants were chosen and were asked to read the information and then were presented a series of images which were attractive and non-attractive. The observations were to be done in order to check the financial altruism or non-financial altruism and was noticed that the participants were choosing on the basis of attractiveness. This explained the evolution of altruism which determines that the people show altruism for more attractive people. The 2- D facial images and online facial database were used for the methodology and paired sample t-test for non-financial altruism were utilized for the experimentation or the study. The more attracted people were assumed to give more positive attribute range than the non-attractive ones (Bhogal, M. S., Galbraith, N., & Manktelow, K., 2016). Various studies have been reported for the past ten years. The whole experiment was based on the attractive and non-attractive images. Introduction Altruism is the word coined by Auguste Comte, a French philosopher; it is derived from Latin word ‘alteri' which means ‘someone else.' In French it is termed as ‘altruisme’ which means selflessness; used as an antonym for selfishness. Altruism is defined as welfare to others which

may 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 or attractiveness towards opposite sex. One is the reproductive success theory determines the natural selection by measuring the fitness of offsprings and by measuring the number of offspring left. According to sexual propaganda theory mate was lead opportunistically, by strength of mate signals, trophic resource, phenotypic characteristics, etc. and explained the genetic diversity maintenance within the population. The Hola effect tells about the observer's feelings, overall impressions of a person on others (Liu, S. Q., Liu, S. Q., Mattila, A. S., & Mattila, A. S., 2016). Darwin and Ronald Fisher gave a great contribution in the sexual theories by explaining that for natural selection the sexual selection is also important and mating with the opposite partner the sperm competitiveness, physical features are also important factors to get attracted (Taborsky, M., Frommen, J. G., & Riehl, C., 2016). The study is done to give an explanation to the sexual selection hypothesis given by Darwin in the year 1871. Altruism is known to be the mating signal which is important to attract and influence the opposite partner forsex behaviour (Shaver, P. R., Mikulincer, M., Gross, J. T., Stern, J. A., & Cassidy, J. A., 2016).The altruism was studied non-financially and financially using DV and IV. IV was the study done on the basis of facial attractiveness that too within the group while the DV determinesthe dependent variable which can be measured by social dilemma or online dictator game. Participants would be more altruisic towards facial attractiveness.Method An experiment was designed within the group of few people or may consider them as participants. Various images were pre-set into the category of attractiveness and unattractiveness;participants were allowed to rate those attractive and non-attractive images.
