As far as I know, before agricultural and industrial revolution, people in hunter gatherer societies spend a majority of their time resting. They spent maybe 4-5 hours a day on hunting, gathering and other stuff. The rest of the day is spent with family and napping/lying/resting.
To answer your question I think that sitting 8 hours every day is not very healthy, but it's far better than standing 8 hours. Break long period of sitting with some walking, stretching or some light exercise, and you would eliminate almost all negative effects of prolonged sitting.
