Turing also turned his math skills to understanding how regular features could emerge on the developing embryo. Scientists since then have applied his equations to the development of such patterns as ...

On the left, Turing’s original test involves a human interrogator (C) trying to identify a machine (A) that imitates a human assistant (B). On the right, the modern Turing-like test replaces the human ...

Turing’s ideas explain how some animal patterns arise. A spot-maker is the most basic version of Turing patterning. It involves two key substances, or morphogens, as Turing called them, that can move ...
