Bombardier Beetle Defies Evolution

The defense mechanism uses features which are common in other beetles and have evolved as variations have been subject to natural selection. Various quinones are commonly produced by cells in the skin of insects to harden their skin into a cuticle, and as they taste bad to predators many insects secrete this to deter predators. Where there are indentations in the cuticle, these can vary to form little sacs which store the deterrent quinone. Where predators develop resistance to this chemical, other related chemicals such as hydroquinone can develop, and in many beetles specialised cells secreting hydroquinone from glands connected by ducts to a reservoir sac which can be closed off by muscles to stop leakage. While all carabid beetles have this sort of arrangement, in some cases Hydrogen peroxide which is a common by-product of the metabolism of cells can become mixed in with the hydroquinone, and some of the catalases which exist in most cells can make the process more efficient. The chemical reaction can produce heat and pressure which pushes out the discharge when the insect is attacked, as in the beetle Metrius contractus which produces a foamy discharge, while a flap forms a valve to ensure that the pressure pushes the discharge out. In other bombardier beetles, muscles controlling the outlet have developed nozzles that can direct an increasingly explosive reaction to squirt the deterrent chemicals at an attacker. More detailed scenarios have been developed showing a series of small changes that could have led to this mechanism.

First: not creditable.
Second: please name the 'assumptions' instead of just talking about it. You sound like a commercial. By the way, called glittering propaganda.
Third: I'm sure that the bug had some other defense that was useless against it's predators, so it changed it's defense.
Fourth: Has he ever considered that our digestive system and BRAIN is more complicated then an abestos lined organ? Oh, and that organ was once a stomach. Thought I would let you know.

Why does this guy make the assumtion that this little beetle would have evolved an explosive chemical reaction powerfull enough to blow up the insect when it first showed up in its genetic profile?
Isnt it more likely that it first evolved just enough explosive chemical to make a small reaction first then eventually through random mutation developed a more and more powerfull explosion?

Has anyone noticed that he never says where he was a professor? That is typical of these fake scientists that claim to support creationism. Where did he get his degree? A diploma mill? That does not make him a professor. he knows nothing of biology or how evolution ACTUALLY works.
