Reproductive Social Behavior: Cooperative Games to Replace Sexual
Selection
Joan Roughgarden, Meeko Oishi, Erol Akçay
Theories about sexual selection can be traced back to Darwin in 1871.
He proposed that males fertilize as many females as possible with
inexpensive sperm, whereas females, with a limited supply of large
eggs, select the genetically highest quality males to endow their
offspring with superior capabilities. Since its proposal, problems
with this narrative have continued to accumulate, and it is our view
that sexual selection theory needs to be replaced. We suggest an
approach that relies on the exchange of direct ecological benefits
among cooperating animals without reference to genetic benefits.
This approach can be expressed mathematically in a branch of game
theory that pertains to bargaining and side payments.

PiP comment: Sounds interesting. Joan (formerly Jonathan) Roughgarden
has a unique perspective on how our own gender identity colors our
thinking about sexual selection.

Quote from the above: "We suggest an approach that relies on the exchange of
direct ecological benefits among cooperating animals without reference to
genetic benefits" is enlightening."
The inference re: the dominance of just "genetic benefits" I consider to
refer to Fisher's outdated concept of what is and what is not "heritable"
and therefore "selectable" in 2006. I also consider the phrase "ecological
benefits" to refer to heritable phenotype fitness benefits and not just
genotype fitness benefits. I argue that TOTAL fitness benefits per selectee
must become mutualised between interdependent sexes within one population no
matter how you define fitness.
