What consequence occurred after the Ice Age ended?

After the Ice Age ended, one of the significant consequences was the rise in ocean levels and the subsequent loss of migration routes. As the glaciers melted and the climate warmed, the volume of water in the oceans increased, causing sea levels to rise. This shift transformed coastlines and submerged land bridges that were critical for migration. For instance, the Bering land bridge, which once connected Asia and North America, was inundated, altering the pathways humans and animals took during the migration.

The other options reflect changes that can occur due to the post-Ice Age environment but do not capture the specific and immediate geological impacts of rising ocean levels. While agricultural development and population growth were likely influenced by the changes in climate and environment, they were not direct consequences of the end of the Ice Age itself. Similarly, while animal migration patterns may have shifted, the immediate result of rising sea levels was more directly related to the loss of routes rather than a decline in migration per se.
