What is the name given to the land bridge that connected Siberia and Alaska?

The correct answer is Beringia, which refers to the land bridge that existed during the last Ice Age, connecting what is now Siberia in Russia with Alaska in the United States. This land bridge emerged due to lower sea levels when large amounts of water were trapped in ice sheets, allowing prehistoric peoples and animals to migrate between Asia and North America. The existence of Beringia played a crucial role in the spread of human populations into the Americas, as it provided a route for migration as well as access to resources. Additionally, the concept of Beringia helps to explain the archaeological and genetic links between ancient populations in North America and those in Asia, providing insight into the peopling of the continent.
