altruism- kin selection theory

why did kin alone fail to explain the results generated from the experiment conducted by Simmons et al (1977)

since only 47% of the siblings said yes when they were asked to donate their kidney (86% of the parents said yes)

mention two strengths of the theory

supported by empirical studies, demonstrated by mathematical computer simulations

Kin Selection Theory (evolutionary theory)

(Hamilton)individuals are more likely to sacrifice themselves for relatives than non-relatives

mention two weaknesses with the theory

cannot explain why people help non-relatives, human kinship isn't necessarily based upon blood tie

Simmons et al (1977)

investigated wheter close relatives were more likely to be kidney donors

mention one possible explanation for the unexpected outcomes of the experiment conducted by simmons et al (1977)

the subject for donation felt very close to 63% of the potential donors, but only to 42% of the potential non-donors
