Vampire bats from the family Phyllostomidae, comprised of three known species and blood sucking leeches (sanguinivores) from four subspecies (Hirudo medicinalis) tested all share common genes.
The vampire bat is a unique evolutionary specimen. The only mammals that survive on blood alone (obligate sanguivory) the 93% protein diet requires specialized kidney function and unique microbiome (gut bacteria) along with an enhanced immune system required for an all blood diet. Interestingly, 87% of the bat salivary proteins are common across the tree of life. 13% was unique, but common to both species.
That leeches and vampire bats share a common ancestry of 4 million years was no huge surprise to geneticists. However, the 13% unique protein genome is also found in a majority population of pastors, priests, and bishops. The remarkable gene has spawned a niche in humanity surpassing the mythical vampire. The preacher—impervious to contradiction through enhanced immunity while addicted to the blood of another is a remarkable connection even I didn’t foresee.
Sucking the life out of humanity without contributing anything. Talk about unprofitable servants! Isn’t that a scripture?
