Final answer:
The similarity between the Karankawas and the Mescalero Apache is that both were nomadic tribes, characterized by their seasonal movements and hunting practices rather than agriculture.
Step-by-step explanation:
The similarity between the Karankawas and the Mescalero Apache is that both were nomadic tribes. Nomadic tribes are characterized by their mobility, often moving seasonally to follow food sources and take advantage of different resources. In the case of the Mescalero Apache, nomadic patterns enabled them to be efficient hunters, especially after the introduction of the horse. The Karankawas, located along the Gulf Coast of Texas, led a nomadic lifestyle mainly focusing on fishing and gathering along the coast and inland waterways. While both tribes had interactions with agriculturalist societies, they did not primarily rely on farming for their subsistence.
