Car vs. Wild - African wild dog - Netflix
The African wild dog (Lycaon pictus), also known as African hunting dog, African painted dog, painted hunting dog, or painted wolf, is a canid native to Sub-Saharan Africa. It is the largest of its family in Africa, and the only extant member of the genus Lycaon, which is distinguished from Canis by its fewer toes and its dentition, which is highly specialised for a hypercarnivorous diet. It is classified as endangered by the IUCN, as it has disappeared from much of its original range. The current population has been estimated at roughly 39 subpopulations containing 6,600 adults, only 1,400 of which are fully grown. The decline of these populations is ongoing, due to habitat fragmentation, human persecution, and disease outbreaks. The African wild dog is a highly social animal, living in packs with separate dominance hierarchies for males and females. Uniquely among social carnivores, it is the females rather than the males that scatter from the natal pack once sexually mature, and the young are allowed to feed first on carcasses. The species is a specialised diurnal hunter of antelopes, which it catches by chasing them to exhaustion. Like other canids, it regurgitates food for its young, but this action is also extended to adults, to the point of being the bedrock of African wild dog social life. It has few natural predators, though lions are a major source of mortality, and spotted hyenas are frequent kleptoparasites. Although not as prominent in African folklore or culture as other African carnivores, it has been respected in several hunter-gatherer societies, particularly those of the predynastic Egyptians and the San people.
Car vs. Wild - Inbreeding avoidance - Netflix
Because L. pictus largely exists in fragmented small populations, its existence is endangered. Inbreeding avoidance via mate selection is characteristic of the species and has important potential consequences for population persistence. Inbreeding is rare within natal packs. Inbreeding is likely avoided because it leads to the expression of recessive deleterious alleles. Computer-population simulations indicate that all populations continuing to avoid incestuous mating will become extinct within 100 years due to the unavailability of unrelated mates. Thus the impact of reduced numbers of suitable unrelated mates will likely have a severe demographic impact on the future viability of small wild dog populations.
