History of Bear in Timeline

By Popular Timelines Editorial Team · Updated: November 28, 2025

Bears are carnivoran mammals belonging to the Ursidae family, classified as caniforms. While only eight species exist today, they inhabit diverse habitats across much of the Northern Hemisphere and parts of the Southern Hemisphere, including North America, South America, and Eurasia. Common traits include large, stocky bodies, long snouts, small, rounded ears, shaggy fur, plantigrade paws with non-retractile claws, and short tails.

1992: Bear Classification into Subfamilies

In 1992, McLellan and colleagues classified bears into seven subfamilies: Amphicynodontinae, Hemicyoninae, Ursavinae, Agriotheriinae, Ailuropodinae, Tremarctinae, and Ursinae.

1997: Ursoidea Superfamily Classification

In 1997, McKenna et al. classified the bear species into the superfamily Ursoidea, with Hemicyoninae and Agriotheriinae being classified in the family "Hemicyonidae".

2005: Phylogenetic tree analysis

In 2005, Flynn's molecular phylogenetic analysis of six genes established the relationship of the bear family with other carnivorans.

2005: Classification of Ursidae in Caniformia

In 2005, Wesley-Hunt and Flynn classified the family Ursidae as one of nine families in the suborder Caniformia, or "doglike" carnivorans, within the order Carnivora.

2006: UNESCO World Heritage Site Designation

In 2006, the Sichuan Giant Panda Sanctuaries, home to around 30% of the wild panda population, gained a UNESCO World Heritage Site designation.

2007: Mitochondrial DNA Sequence Phylogeny

In 2007, a phylogeny based on complete mitochondrial DNA sequences from Yu et al. showed that the polar bear and the brown bear form a close grouping, but the relationships of the other species are not well resolved.

2017: Genetic Study of Ursine Bears

In 2017, a genetic study by Kumar et al. concluded that Ursine bears originated around five million years ago, and there has been extensive hybridization among the different species.
