What are the characteristics of primitive ancestors in sculpture?

In terms of sculpture, primitive ancestors have noticed the image capture from the carving and grinding of stone tools to the modeling of pottery sculptures. All the images of people and animals they come into contact with and are interested in are willing to be shaped with clay. Taking the pictographic pottery unearthed in Shandong as an example, the author's keen observation of the images of pigs and dogs who have the most contact in life is obviously inspired. Another example is the painted pottery bottle with the head as the mouth ornament unearthed in Qin 'an, Gansu Province. Because the bottle is round, like a standing body, it becomes a vivid whole portrait made together. This method of absorbing images from life and transforming it into a creative method of artistic works is a valuable contribution of our ancestors in sculpture art five or six thousand years ago. It took the first step for later realistic sculpture creation.
