What did the Scottish geologist James Hutton claim about a possible evolutionary mechanism similar to natural selection (many years before Charles Darwin and Alfred Russel Wallace)? selection for heritable variation could improve neither varieties nor species of plants and animals artificial selection of crops and livestock improves plants and animals more than natural selection only natural selection, not artificial selection, could lead to improved plant and animal species only artificial selection, not natural selection, could lead to improved plants and animal species selection for heritable variation could improve varieties, but not species, of plants and animals
