By 2009, at least 17 different hybrid grizzly-polar bears had been born in zoos across the world. The number of confirmed hybrids has since risen to eight, all of them descending from the same female polar bear.[3]. This appears to reflect a process in which a population of polar bears was left behind as the species retreated northwards at the end of the last ice age, with male brown bears subsequently introducing genes from the adjacent mainland, but female brown bears being generally unable or unwilling to swim across several kilometres of open ocean to reach the islands (thus the lack of exchange of mitochondrial DNA). The Brown Bear's is Ursus arctos. The number of pizzly bears is not well known, but it is believed that their populations are increasing as the ranges of polar bears and grizzly bears overlap due to climate change. By one convention,[29] the name of the sire comes first in such combinations: the offspring of a male polar bear and a female grizzly would be the suggested nanulak or a "pizzly bear", while the offspring of a male grizzly and a female polar bear would be a "grolar bear" or possibly an aknuk.
