Both the bears are living happily on an iceberg.
Trait selected-white furTrait selected against- brown furType of adaptation- Physical (color) environment/environmental change- Predator (poacher)
A poacher approaches the iceberg and can only see the brown bears.
The poacher then proceeds to kill the brown bears because the white bears are obviously hiding and blending in to the snow.
Only the white bears are left because the brown bears could not do anything to save themselves.
