These studies suggest that the hyena family tree includes four living species with varying genetic diversity and evolutionary histories, influenced by ecological specialization and historical migrations.
The family Hyaenidae, commonly known as hyenas, is a small but ecologically and socially diverse group within the mammalian carnivores. Despite having only four extant species today, hyenas have a rich evolutionary history that includes a wide range of ecological niches and social structures. This synthesis aims to provide an overview of the evolutionary history, genetic diversity, and ecological adaptations of the hyena family, with a focus on the family tree and the relationships among the extant and extinct species.
Evolutionary History and Diversity:
Genetic Diversity and Population Decline:
Phylogenetic Relationships and Gene Flow:
Ecological Specialization and Adaptations:
Historical Biogeography:
The family Hyaenidae has undergone significant evolutionary changes, from a highly diverse group in the Miocene to the four specialized species we see today. Genetic studies reveal low diversity in some species due to historical population declines, while others maintain higher diversity. Phylogenetic analyses indicate complex relationships and gene flow among species, with significant ecological adaptations shaping their evolutionary paths. The historical biogeography of hyenas highlights multiple migrations and a rich fossil record that provides insights into their past diversity and distribution.
