Why do scientists think that people traveled the land bridge around 11000 BCE?

Scientists believe that people traveled the land bridge, known as Beringia, around 11,000 BCE due to evidence of human migration patterns and archaeological findings. During the last Ice Age, lower sea levels exposed this land bridge between Asia and North America, allowing hunter-gatherer groups to follow migrating animals for food. Additionally, fossil and tool discoveries in both regions support the theory that these early populations moved across the bridge in search of resources. This migration is considered a significant event in the peopling of the Americas.
