Question

Quizplus · Accepted Answer

Changes in climate have had a significant impact on the present day distribution patterns of plants and animals, with the ice ages of the Pleistocene playing a particularly important role in shaping the distribution of species. As the climate changed, species had to adapt and migrate to new areas in order to survive. This has led to the development of distinct biogeographic regions based on their unique climates and the plants and animals that can thrive within them.
