It is difficult to give a complete and accurate picture of what the indigenous peoples of the Americas looked like before the arrival of Europeans because there were many different tribes and nations, each with their own unique physical characteristics. However, it is generally accepted that the first people to arrive in the Americas were indigenous to Asia and migrated across the Bering Land Bridge around 12,000 years ago. Over time, these people diversified and formed distinct groups with their own cultures, languages, and physical features. Some indigenous peoples were tall and thin, while others were shorter and more muscular. Skin tone could range from very light to very dark, and facial features varied widely. Hair color and texture also varied greatly, from straight black hair to curly red hair. It is important to note that there is no single "Native American" or "Indigenous" physical appearance, and any generalization is likely to be inaccurate and oversimplified.
