That's why they go on about "information", it puts a new ill-defined concept into the mix that can be used to make claims without any real support.
Ultimately the DNA just results in the creation of many different molecules which all float around reacting with other molecules.
People think of DNA as a blueprint, but it's not.
A good example is one experiment where during the development of an embryo they took a patch of skin from the front of the animal and grafted it onto the back. Big deal right? Well during development the nerves that normally grew out to go to that patch of skin
turned around and started growing towards the back!
It's not the blueprint that determined where the nerves grew, the skin itself was creating a chemical signal (determined by its DNA) that triggered behaviour in other cells (determined by their DNA).
I think it's that blueprint mental model that actually makes it difficult to understand how evolution can actually produce the kinds of changes it does.
