You might have seen the reality shows that put multiple bachelors together and it ends up in dramatic cases of cheating and adultery. Mixing attractive people provides a good recipe for amorous behavior. Polygamy should follow in close-knit and passion-filled social environment. However, we do know that individual male-female bonding can arise and be maintained even under such situations. How can monogamy be sustained?
Kirill Tokarev and colleagues used zebra finches as model to understand development of monogamy in a close-knit social structure. Female zebra finches are attracted to the singing of the male song, and in a community, multiple male songs would be heard by the female. Evolution of monogamy would require atleast two conditions:
1. after bonding, females responding to their partner's singing only,
2. to maintain harmony in the society males not being aggressive to other singing males.
How do both these conditions arise in zebra finches? To know that, please listen to Kirill.
