On the planet Nova 3, there exists a species of intelligent, Macropodidae-like creatures called Novians. The species is mostly herbivorous, although meat is eaten on special occasion. Their planet is covered by many biomes, such as rolling plains, dense jungle, savannah, and tundra. The Novians evolved from bipedal horse-like creatures 175,000 years ago, and they have four stomachs. Most of what they eat is grass and roots. They used to be prey to creatures called Daystalkers, but those all went extinct long ago. Novian culture never developed the wheel, but they were able to advance to an era similar to humanity's space age.
My question is: could a modern society exist without the wheel?
