dolls representing infants, animals, and soldiers, as well as representations of tools used by adults are readily found at archaeological sites.
The earliest and most primitive dolls were simple wooden carvings and bundles of grass.
Egyptian dolls were sometimes jointed so that their limbs could move realistically.
By the early 20th century there were dolls that could say “mama”.
Today there are computerized dolls that can recognize and identify objects, the voice of their owner, and choose among hundreds of pre-programmed phrases to respond.
