Document Summary
Chapter 9 kinship: sexual reproduction, sexual selection, mating systems point is to end up with offspring, this leads to parent and kids. Kin selection: this is the basis of the theory of kin selection (developed by w. d. Family dynamics: kin selection also makes predictions about family dynamics (emlen evolutionary biologist) Some are solitary: so how did eusociality evolve in these species, we must look at gene-- Social insects: recall back in evolution/genes lecture, we discussed that chromosomes are diploid (have two forms) one from father, one from mother. In some social insects, the genetics are different: males are haploid (only have one sex chromosome, from an unfertilized egg, females are diploid (have two sex chromosomes, from a fertilized egg) If you think about the relationship between parents and offspring, you see that each has a different goal: parents: invest enough to bring offspring to weaning or fledging, then invest in new young.
