Grolar Bears and Narlugas: Rise of the Arctic Hybrids

[lilyannerose]

Lack of suitable mates often trigger the adaptive behavior of looking further afield and/or accepting less suitable mates. This could extend to mating outside the traditional mate pool. This results in testing of the definition of species. Traditionally a species of sexual organisms like humans, dogs and bears is defined to be any population sufficiently similar genetically and behaviorally so that when individuals of different sex of breeding age are brough together, they can mate and produce offspring that are both viable and fertile.
