Explanation:

The thumb is crucial for fine - motor skills and grasping objects. Tasks like fastening buttons, picking up books, turning doorknobs, holding tools, and using a screwdriver rely on thumb function. Without thumbs, complex tool - use and manipulation would be severely impaired, likely hindering the development of civilization as tools are fundamental to technological and societal progress.

Answer:

No, civilization would likely not be as advanced. Without thumbs, tasks that require precise grasping and manipulation of tools, which are essential for technological and industrial development, would be extremely difficult or impossible. This would have limited the ability to build, create, and innovate, thus stalling the progress of civilization.
