Document Summary
One of the realizations that grew out of sociobiology was the importance of getting more of your genes in to the next generation. This could be accomplished in ways other than having your own offspring (i. e. by taking care of siblings). Hymenoptera wasps, bees, ants (all social insects except termites are in this order) Haplodiploidy unfertilized eggs become males and are haploid, fertilized eggs become females and are diploid. * you"re better off helping your mom raise more sisters so you pass on more of your gene. So females benefit from raising their sisters more than from having their own daughters! Males benefit from raising their brothers and sisters. (for haplodiploidy) Get as much as you can from your parents before they cut you off. Parents" job is to continue making kids, therefore, she has to invest into her next offspring. Sibling rivalry (i. e. baby birds in nest they fight each other for the food)
