"Something like Demski's filter" might be helpful; but Dembksi's
filter itself is of no help.

A recent paper suggests that the original function of these
heme-carrying proteins was not to carry oxygen but to perform
a detoxification process. Thus myoglobin, as an oxygen carrier,
appears to have its origin in an older protein with a different
Now, while there is no way to rule out "some form of actualized
design" behind the progenitor of oxygen-carrying hemoglobins,
what exactly is there to support this belief? Personally, I find
it hard to make the case for design based on the negative argument
presented. Positive evidence is what's needed.
