Document Summary
Chapter nine developmental stages through the life cycle. Demography and conservation: box 9. 2 the legacy of life histories. This chapter describes the life cycle of primates (covering some of the same material covered in the life course lecture), with an emphasis on sex differences. It begins (fertilization to birth) with a description of how the sex of primates is determined (by whether the sperm is bearing an x or a y chromosome), in comparison with some other animals. Be sure to know the meaning of the terms such as heterogametic, homogametic, primary sex ratios and secondary sex ratios. The rest of the chapter is straightforward (and corresponds nicely with the lecture), considering maternal, paternal, and alloparental care of infants; then weaning conflict (predicted by parental investment theory), and then the challenges faced by juveniles.
