Animals, Evolution, and Mechanical Infusion

The rate of evolution within the animal kingdom has drastically increased as the third millennium progressed, with the novel implementation of the mechanical nature into themselves and their offspring, into body and soul, through a process known as mechanical infusion.
The legitimacy of this phenomenon is a heated debate among Earthlings, more so than the nature of evolution as a whole, and questions regarding potential human involvement, deliberateness as opposed to a natural course, and whether these creatures are biotic or abiotic are common topics.

The difference between animals that are mechanically infused and artificial robots lies within the fallacy of their internal processes and hardware as opposed to the neatness of traditional machines. Biological organs are typically found fused to metal, wire, and other parts when dissected.
These components are able to self-replicate, as with traditional biological reproduction, continuing the process of evolution through 'genetic' mixing with individuals of respective species and mutation.

Mechanical infusion currently only affects undomesticated animals (from mammals, to arthropods, to extremophiles), as animals in captivity are selectively bred. This is more common among terrestrial and arboreal animals, but not unheard of in marine life. This process has not (yet) reached plants or fungi and currently only affects Earth.

Mechanically infused animals are edible due to their plating consisting of a biodegradable flesh-like metal alloy. It's been noted to taste like "licking a fried streetlamp" when raw and "surprisingly pleasant" when cooked, as with the wires. It's tougher than traditional meat. However, it can be softened through cooking. The 'skeletons' are commonly described as "fucking garbage" and are discarded, as with biological skeletons.
The blood, commonly called ichor is also edible and garners the same responses.

How this process has not occurred with humans (including mutants and astronomical variants) naturally is unclear.

Trivia

• Mechanically infused animals have a better chance of getting along with machines than purely organic creatures.
• Most of them have their original vocal range, but can also beep and boop.
