"To twist an old quip: Theories come and theories go, the environment remains. The first half of the 20th century was a big bang for the idea that every child was born a blank slate to be shaped by family and social environments. During the second half of the 20th century, the obtuse pendulum of fashion swung in the other direction, until everyone, down to every newspaper editor and science writer, shouted at the public that no, it's not environment but genes and heredity that shaped people. Now the pendulum is swinging the other way (yes, I wrote a book about it), but it may take certain media science pundits another decade before they realize the goose is running away from them at high speed."

My own take on this article is that it helps modify the current belief that genes are everything, but I would argue that genes are something, and that they create the matrix within which environmental influences play out. A person may be born with a genetic susceptibility to stress-related illnesses such as mood disorders or anxiety disorders, say, but the provision of positive environmental influences, especially during the early years, can tweak gene expressions to avoid these illnesses in later life. In the end, its the particular dance between genes and environment that gives us health or disorder. Ultimately, I think an individual's neurodiversity comes about as a result of nature AND nuture.
