Here's an interesting part that's buried by the end:

>Another area of research focuses on maggots’ wound-healing properties. “Clinical and anecdotal evidence suggested that maggots improve or accelerate and stimulate a wound to heal,” says Nigam. “We were really interested in why this could be possible when that’s of no evolutionary interest to the maggot at all. We’ve discovered that it’s more than likely an inadvertent happening. > >“The growth factors [hormones] that are produced have a very similar structure to the human molecules and that is how perhaps by accident the human wound is stimulated to heal faster. We’re going to investigate that further.”

Just another example of evolution being taken for granted. As far as I can tell the theory doesn’t even explain the origin of species, let alone the wound-healing properties of maggots.

Except your concern is addressed even in the part that I quoted:

"The growth factors [hormones] that are produced have a very similar structure to the human molecules and that is how perhaps by accident the human wound is stimulated to heal faster."

No idea how you got from that to "evolution can't even explain the origin of species", but it seems to me you're not exactly looking for truth here.
