Q
Changes in ecosystems can lead to speciation. A high concentration of copper in soil is toxic
to most plants. In some areas where the soil is polluted with copper, populations of grasses
are found to be growing. These populations of grass belong to a species also found growing
on unpolluted soils.
It has been suggested that a new species of grass may evolve on soil that has been polluted with
copper. Explain how this new species might evolve. (5 marks)
