Which term describes theories that assume all societies follow the same path from simple to complex?

• A. Multilinear
• B. Unilinear
• C. Circular evolution
• D. Postindustrial

Answer: (B)

The idea being tested is the belief that there is a single, universal path of development that all societies follow, moving from simple to complex in the same order. The term that captures this view is unilinear evolution. It holds that every culture progresses along one fixed ladder toward the same advanced outcomes. This concept was tied to early theories that used Western societies as the benchmark for development, but it’s been challenged for being ethnocentric and overly deterministic.

In contrast, multilinear evolution argues that different societies can follow various routes to reach similar levels of complexity, depending on local conditions, technology, and culture, so there isn’t just one universal path. Circular evolution, if discussed, implies cycles or repeated returns rather than a straight progression, which isn’t the standard way to describe a universal developmental path. Postindustrial describes a later stage of economic development—dominated by services and information—not a claim about a universal sequence from simple to complex.
