There is an important part in what is meant by "machine".

Mechanics, strictly speaking, is pervasive in but not sufficient to account for the life process.

There's something else going on that looks like classical teleos and both the cells and the organism have it.

There's interesting work to get teleos out of mechanics in far from equilibrium thermodynamics.. Prigogine, Kauffman, Wolfram, Deacon, England even Dennet.
