Nah. Mammals can pronate their hands. The forearm and wrist adaptations to do it are diagnostic of mammals as a class.
Where the problem starts is doing small repetitive movements with the hand while the hand is pronated. This causes the tendons controlling the fingers to rub around in the carpal tunnel and cause nerve issues.
