This is surely an extraordinary process and it brings the following
questions to the mind:
1) How does the gnat know that there is an clotting enzyme in the human body?
2) In order to produce a neutralising secretion in its own body against that enzyme, it
needs to know the chemical of the enzyme. How can this be possible?
3) Even if it somehow attains such a knowledge (!), how come can it produce such a
secretion in its own body and constitute the "technical rigging" needed to
transfer it to its sting?
