Group structure and kinship in beluga whale societies [PDF]
Scientific Reports, 2020 AbstractEvolutionary explanations for mammalian sociality typically center on inclusive-fitness benefits of associating and cooperating with close kin, or close maternal kin as in some whale societies, including killer and sperm whales. Their matrilineal structure has strongly influenced the thinking about social structure in less well-studied ...
