Above is the Ngram<\/a> result for paradigm shift<\/a>, a ubiquitous descriptive concept which can be quite slippery when applied to contemporary science. For example, every few years there is always a new “revolution” which is going to overturn “Darwinism.” Be it punctuated equilibrium<\/a>, symbiogenesis<\/a>, or epigenetics<\/a>. But over time revolutionary fervor abates, and the orthodoxy remains standing, albeit with modifications and alterations, making it all the more robust.<\/p>

I thought of this when I saw Andrea Cantor’s comment below<\/a> in relation to twin studies:<\/p>

Twin studies underestimate heritability only if you subscribe to the crude notion<\/strong> that the effect of genes is additive, i.e., keeping “environments” the same, the more similar two people are genetically the more alike they will be. This ignores everything we now know<\/em> about the way genes work.<\/strong><\/p>

Genes are not self-activating: they do not turn themselves on and produce traits. Genes do not, in fact, produce anything. Genes are turned on and off by the epigenome <\/strong>in response to environmental inputs. If you are inclined to doubt this, then consider: If all the cells in our body are supposed to contain identical ...<\/p><\/blockquote>
