and treeless tundra, it was covered with grasses and plant life, attracting the large animals that early humans hunted for their survival. The first people to reach North America almost certainly did so without knowing they had crossed into a new continent. They would have been following game, as their ancestors had for thousands of years, along the Siberian coast and then across the land bridge.
Race Type
The most marked physical characteristics of the Indian race type are brown skin, dark brown eyes, prominent cheek bones, straight black hair, and scantiness of beard.
