There was, long ago, a confusion in social science circles. Alfred Marshall, Karl Pearson, Bernard Shaw, Ronald Fisher, etc, framed the question in terms of nature versus nature. However, this framing was later critically addressed, by prominent figures at the time within biology and neuroscience.
In 1956 (2), Donald Hebb wrote that it is 100 percent both, that the nature versus nurture is misleading and incorrect, that there is no nature part and no nurture part. They cannot be separated or calculated as fractions. Environment determined how genes are expressed and while absence of one (now called developmental resource) causes some behavior not to be learned, no behavior is attributable to some environment or to some genetic component, because mere presence of that independent of the whole complex system does not produce that behavior. He was later elected president of the American Psychological Association. In his earlier famous coalitional neural networks monograph (1), he wrote that attributing substantial differences in human learning behavior specifically to different genetics is very misleading. Most significant genetic differences in a species, he argued, do not themselves cause any behavior difference when small and cause obvious physical illness when sufficiently great.
Before him Raymond Wheeler wrote much the same thing in places like Psychological Review, and Conrad Waddington wrote the same thing on numerous occasions in his well known books in 1949, 1954, 1957, etc, and in places like Nature. Today we talk about whole developmental systems and developmental resources that must be present at a certain time for something to occur but none of which by itself codes or causes anything. So much for the scientific history of this.
