Document Summary
Parental investments: males contribute a great amount of investment, their level of free will decreases, the cost increases as the investments increase. Reproductive asymmetry: towards female investment and less of male, primates have strong asymmetry roles, their reproductive attitudes, 15mm of sperm (male) that"s all the investment they give, so the females have more investment in the birthing. Benefits of polyandry: mating with more than male, indirect genetic. If we mate with more than one there should be one that would be fertile enough. The quality of genes in animals can be seen as a shopping spree that you want to pass on to your offspring. One half is you, the other half is something you can choose. Mating with more than one the genes that would be passed would be of high quality. Genetic compatibility making good matches between males and females. To know the best phenotypes to be passed on you have to get high quality: direct material.
