Question

in africa,the weak animals and birds are eliminated and breeding is done only between strong male and female animals or birds in the event of diseases outbreak and drought they send domesticated animals and birds to friends and relative in far off location why do they do this

Answer 1

Continued mating between the superior party among the African animals and birds  ,restricts the adptablity towards the adverse conditions as the result at the time of calamities (eg:droughts) the superior animals with restricted protections towards the so held situations, shows a major decline in their population and since to be enjoying the only tittle of the specie , it leads to extinction of the specie with them.

So to protect their high yield superior animals and birds they send them to the more safer zones, may be their friends, relatives areas placed far away from the calamity and bring them back after the relief.
