My initial thoughts on the Cousins et al. paper on a deep structure for Homo sapiens origins (Nature Genetics)

Simplicity in all things is highly praised; but in order to achieve it, one should be extremely skilled and astute. (G. Spalletti)

Speaking unstable words is a sign of truth . . . alien to artifice, and being touched by the truth, correcting yourself, crying out as you were enraptured by the truth, and finally showing a diligent negligence and a negligent diligence, all of this can give the appearance of truth. (D. Barbaro)

Art must simulate chance, and remain concealed. (Ovid -- Ars Amatoria 3.210)

And, to use possibly a new word, to practice in everything a certain ‘nonchalance’ [sprezzatura] that shall conceal art and show that what is done and said is done without effort and almost without thought. (Castiglione -- The Book of the Courtier)
