Some food for thought, i brought up nylon eating bacteria earlier. Again popular science where a layman such as myself is usually a decade behind...
In 2016 japanese scientists discovered a new bacteria strain that can eat PET (polyethylene teraphthalate)
The newfound species -- named Ideonella sakaiensis 201-F6 -- breaks down the plastic by using two enzymes to hydrolyze poly[ethylene terephthalate], or PET.

Man made material, invented in 1941. Scientists are just as stumped as they were with the nylon eaters, they cannot explain how this capability evolved in ~60 years.
Keep in mind, it took 60 million years for fungus and bacteria to develop the capability to produce enzymes to digest lignin, the material that plants evolved to create wood.
Remember, all that undigestable, non-biodegradable wood ended up buried, unable to rot, eventually became what we call coal.
