Research finds positive relatedness among emerald coral gobies, suggesting kin selection as a key factor in their social structure. The study reveals that group members are more closely related to each other than to individuals from different reefs.
A team led by Dr Bill Hughes found that ancestral females in colonies of bees, wasps, and ants were monogamous, supporting the theory of kin selection. This study provides conclusive evidence that kin selection explains the evolution of social insects.
Edward O. Wilson's article in BioScience presents a new perspective on the evolution of eusociality in insects, suggesting that natural selection acts on nascent colonies rather than individual traits. This challenges the traditional explanation based on kin selection, highlighting the complexity of social organization in these species.
A study by UC Berkeley researcher Alan Krakauer found that subordinate male wild turkeys benefit indirectly from helping their dominant brothers breed, gaining an average of 1.7 offspring. This cooperative behavior is a key example of kin selection, which favors cooperation over selfishness.
Researchers found that social insects' policing behavior against cheating workers cannot be explained by relatedness alone. Instead, the energy invested in laying eggs detracts from colony efficiency and growth.
