I can think of a few microorganisms, possibly the tubercle bacillus, the syphilis spirochete, the malarial parasite, and a few others, that have a selective advantage in their ability to infect human beings, but there is nothing to be gained, in an evolutionary sense, by the capacity to cause illness or death. Pathogenicity may be something of a disadvantage for most microbes, carrying lethal risks far more frightening to them than to us. The man who catches a meningococcus is in considerably less danger for his life, even without chemotherapy, than meningococci with the bad luck to catch a man.
I am proud that I am an Australian, a daughter of the Southern Cross, a child of the mighty bush. I am thankful I am a peasant, a part of the bone and muscle of my nation, and earn my bread by the sweat of my brow, as man was meant to do. I rejoice I was not born a parasite, one of the blood-suckers who loll on velvet and satin, crushed from the proceeds of human sweat and blood and souls.of Bin Bin
A huge parasite in the marketplace, feeding and fattening itself off of local television stations and copyright owners of copyrighted material. We do not like it because we think it wrong and unfair.jack valenti
This essay treats the most celebrated story in the extreme simplification in an adult parasite - in the interests of illuminating, reconciling, and, perhaps, even resolving two major biases that have so hindered our understanding of natural history: the misequation of evolution with progress, and the undervaluing of an organism by considering only its adult form and not the entire life cycle.stephen jay gould
The parasite has somehow evolved to turn off the host's defenses, presumably by disarming the crab's immune response with some chemical trickery that fools the host into accepting the parasite as part of itself. ...The adult parasite castrates the host, not by directly eating the gonadal tissue, but by some unknown mechanism probably involving penetration of the interna's roots around and into the crab's nervous system.stephen jay gould
In short, the root-head turns the crab into a Darwinian cipher, a feeding machine working entirely in the parasite's service. The castrated crab can make no contribution to its own evolutionary history; its "Darwinian fitness" has become flat zero. ...But ever so carefully, for the parasite must maintain the crab in constant and perfect servitude - not draining the host enough to kill this golden goose, but not letting the crab do anything for its own Darwinian benefit.stephen jay gould
‘You didn't build that’ will be Obama's political epitaph: With these remarks, Obama has come out of the closet as a most odious collectivist, who believes religiously that government predation is a condition for production. Or, put simply, that the parasite created the host.ilana mercer
"Perfect replication is the enemy of any robust system... Lacking a central nervous system much less a brain the parasite is a simple system designed to compromise a very specific target host. The more uniform the host, the more effective the infestation."daniel suarez
The man who attempts to live for others is a dependent. He is a parasite in motive and makes parasites of those he serves.Ayn Rand
