• It created land bridges where ocean had once been.
• It required people to create new shelters.
• It required people to form larger communities.
O It required people to live closer together.
• It created land bridges where ocean had once been.
The last ice age, which occurred around 10,000 to 20,000 years ago, had a significant impact on human migration. It created land bridges where the ocean had once been, allowing humans to migrate to new areas. This was because large amounts of water were trapped in the form of ice, causing the sea levels to drop and exposing new land. These land bridges, such as the Bering Land Bridge between present-day Alaska and Siberia, provided pathways for humans to migrate to different continents.
Additionally, the ice age required people to create new shelters due to the harsh and cold conditions. As the temperatures dropped and ice covered many regions, humans had to adapt by constructing new types of dwellings to protect themselves from the cold. This likely led to the development of more advanced and innovative shelter designs.
Moreover, the ice age necessitated people to form larger communities. The challenging environmental conditions pushed humans to gather in groups for protection, food sourcing, and sharing resources. By living in larger communities, people could better cooperate, share knowledge, and increase their chances of survival during this difficult period.
Overall, the last ice age influenced human migration by creating land bridges, requiring the creation of new shelters, and promoting the formation of larger communities.
The correct answer is: It created land bridges where ocean had once been.
During the last ice age, which occurred from about 110,000 to 12,000 years ago, large portions of the Earth were covered in thick ice sheets. As the ice expanded, it caused a significant drop in sea levels. This drop in sea levels exposed land bridges in various parts of the world, connecting previously separated land areas. These land bridges served as new pathways for human migration.
For example, the Bering Land Bridge, also known as Beringia, connected Asia and North America across what is now the Bering Strait. This land bridge allowed early humans to migrate from Asia to North America, and it is believed that these migrations eventually led to the colonization of the Americas by humans.
These land bridges created by the last ice age played a pivotal role in shaping human migration patterns and the spread of human populations across the globe.
