What of the following contributed to the success of the Native American groups of the far north?

The success of the Native American groups of the far north was largely attributed to their deep understanding of the harsh Arctic environment, which allowed them to develop specialized hunting and fishing techniques. Their use of materials available in their surroundings, such as seal skin for clothing and kayaks for transportation, further enhanced their adaptability. Additionally, strong communal ties and cooperative social structures facilitated effective resource sharing and survival strategies in a challenging climate.
