Vocab Word: the altruism of an individual benefits it close relatives
kin selection
This type of phylogenetic analysis was used to infer the ancestral mating systems of eusocial Hymenoptera species.
Ancestral state reconstruction
What mating systems did the study suggest to be derived from ancestral linages of Hymenoptera?
Facultative low polyandry and polyandry mating systems.
Which artist hasn't released an album since 2016?
Rihanna
What is the hypothesis that was explored in this study?
If kin selection is important, monandry should be ancestral, as it maximizes relatedness.
What does it mean to be scored for reproductive totipotency? What was the scale used?
Workers either retained or lost the ability to mate and reproduce (1 or 0).
Which primary factor did Hughes et al. propose that influences the transition from solitary to eusocial lifestyles?
Increased fitness through indirect benefits from helping relatives.
Who won season 6 of Love Island USA?
Serena and Kordell
The traditional view is that eusociality evolved because of the direct benefits of altruism and the close relatedness of individuals. What is the idea that challenges this view?
Eusociality evolved due to the direct benefits of cooperation - individuals cooperate because being part of a social group increases their fitness.
The software program used for evolutionary analysis in the Role of Kin Selection test:
Mesquite
The inclusive fitness theory suggests that polyandry in eusocial taxa is likely to evolve after certain conditions are met. What condition is typically required for this evolution?
Only after workers have lost reproductive totipotency.
