Final answer:
The Inca Empire made their home in the Andes Mountains and had a highly developed civilization with an extensive road system.
Step-by-step explanation:
The ancient civilization that made their home in the Andes Mountains is the Inca Empire. The Inca Empire was established in Peru in the early 12th century and lasted until the Spanish invasion in 1532 CE. They built an empire that covered Peru, parts of Ecuador, Bolivia, Argentina, and Chile along the chain of the Andes Mountains.
The Inca Empire developed a highly efficient road system that rivaled that of the Romans. The roads enabled the rapid movement of their army and facilitated communication. The Inca people were also known for their impressive architectural skills, as seen in cities like Cuzco and Machu Picchu.
