The former is a mathematical expression denoting an understanding of physical forces. The latter by default postulates a sole cause that omits intelligent design. This is due to a philosophical stance that defines science as incapable of, or disinterested in, anything beyond what is physically observed. Bull. Evolution by mutation and natural selection is an algorithm, and is thus as much as mathematical model as f = ma, albeit more complicated.
Evolution by mutation and natural selection is an algorithm . . .Perhaps these may be explained in terms of algorithms (as may anything that is intelligible and intelligently designed), but in essence they are physical processes interpreted post facto as causative of all speciation.
