The population has also adapted to feeding on dry rubber seeds.

By this means, the population adapts genetically to its circumstances.

But for natural selection to help populations adapt to the Western diet, we'd have to be prepared to let those whom it sickens die.

During the 1980s and 1990s, studies of the process by which populations adapted to food stress as food security worsened received much attention.

The answer has been given since Darwin's time: because the sexual populations adapt better to changing circumstances.

The local population adapted relatively easily to Roman culture.

But it was also possible to make direct studies of how a single population adapted to changes taking place in its local environment.

A high incidence of the disease indicates the population adapted poorly to its environment or was under nutritional stress.

They found that the sexual and asexual populations adapted equally well to the new environment.

Under this philosophy use of free ranging populations of native animals adapted to the environment makes environmental sense.
