No, but they learn the words for various body parts very early in life, usually before the age of 2 and beginning around 1-year-old. A 2-year-old also has significant physiological and neurological constraints on vocalizations.

There are also cognitive development constraints, of course.

The question is, from where do we get the correlation? If it's physiological or neurological, then there's nothing to support fanciful claims of innate language models. It's the cognitive constraints that can support fanciful claims, but you have to first show that it's those constraints, rather than the physiological or neurological constraints, that are controlling word choice.
