farmers have selected and bred plants and animals to favor, or bring out,
characteristics they desired. For example, cows that produced large amounts of
milk were selected for breeding, while poor milk producers were not allowed to

these desired characteristics were selected for breeding. Over time, these
preferred breeds became more common than earlier, less desired types. This
selective breeding is called artificial selection.
In this
passage, Camp and Arms explain how this same process occurs naturally. The
theory of evolution by natural selection was put forward in a joint presentation
of the views of Charles Darwin and Alfred Russell Wallace before the Linnaean
Society of London in 1858. Darwin and Wallace were not the first to suggest that
evolution occurred; but their names are linked with the idea o
A. Its definition.
