Selection on the joint actions of pairs leads to divergent adaptation and coadaptation of care-giving parents during pre-hatching care

We used experimental evolution to investigate how jointly expressed actions evolve upon exposure to a new environmental challenge.

Multilevel selection leads to divergent coadaptation of care-giving parents during pre-hatching parental care

|
By Rahia Mashoodh, Sonia Pascoal, Swastika Issar, Darren Rebar

New Results doi: https://doi.org/10.1101/2022.05.23.493134 Abstract Parental care often involves coordination between the mothers and fathers. Their coordination is partly due to flexible "negotiation rules" that allow mothers and fathers to respond adaptively to each other in real time, but could also be due to divergent environmental conditions that cause different negotiation rules to evolve in different populations through coadaptation.
