Scientific Inquiry Conclusion:
"To explore the effects of promiscuity on the genetic level, Mariam
Okhovat and colleagues took a closer look at the expression of avpr1a, a
gene that predicts sexual fidelity in males and that's well known to
play a role in a spatial-memory circuitry. Lower expression of the
related receptor V1aR in certain brain regions is associated with a poor
memory for locations of aggressive interactions with other males, a
result that could lead to wandering (and contact with non-pair females).
By contrast, abundance of V1aR is linked to a better spatial memory for
past aggressive encounters, and less wandering."
