This interesting article elaborates how the latest neuroscience studies show how it is second nature for babies learn two languages at the same time. The article, though, I think isn’t asking the most fertile question when it starts off with: “When do babies learn language?” and “Is it okay for babies to learn two languages?” Not only is it okay, it’s scandalous that our children aren’t learning at minimum three, four, even a handful of languages when it is mere child’s play for a brief window.
But for me, the real question (or one of them) is: Who invented language? I argue in The Philosophy of Childing that the evidence is overwhelmingly compelling that children invented human language.
Here’s a snippet of how I put it:
Is it highly probable that children were the originators of human language—and just as likely that they are the principal creators of new languages. Consider the development of a form of creole in Hawaii after the explosive growth of sugar plantations on the islands in the late 1900s brought with it a tremendous influx of laborers from places like China, Japan, Korea, Puerto Rico, and the United States. While adults among the different groups made scant and halting progress in communicating with one another, the children made comparatively fast work inventing a nuanced pidgin language. They soon were able to converse with one another, while their parents couldn’t make heads or tails of what their children were saying.
