When we transplant organs, we are enabling viruses to jump natural barriers between species.
Pretty much everybody knows there are not enough organs for all of those patients who need to get transplants, and what happens is, is that organs are actually directed in liver transplantation to those patients who are the sickest. So the patients who have the greatest chance of dying in the next three months or so are the ones who get the priority for the liver transplant.
Viruses have to live somewhere. They can only replicate in living creatures. So, when the Ebola virus disappears between outbreaks, it has to be living in some reservoir host, presumably some species of animal.
The risk from viruses is an unanswered question - and it won't be answered until you have had organs transplanted into humans over many years.
But we must here state that we should not see anything if there were a vacuum. But this would not be due to some nature hindering species, and resisting it, but because of the lack of a nature suitable for the multiplication of species; for species is a natural thing, and therefore needs a natural medium; but in a vacuum nature does not exist.
It is natural selection that gives direction to changes, orients chance, and slowly, progressively produces more complex structures, new organs, and new species. Novelties come from previously unseen association of old material. To create is to recombine.
Moreover, the concern of some that moving DNA among species would breach customary breeding barriers and have profound effects on natural evolutionary processes has substantially disappeared as the science revealed that such exchanges occur in nature.
The natural barriers between England and Scotland were not sufficient to prevent the extension of the Saxon settlements and kingdoms across the border.
There is an important distinction between barriers to entry and barriers to imitation.
I believe that there are barriers, educational barriers, cultural barriers, societal barriers, that are keeping people from accessing the promise of a vibrant free enterprise economy.
Why were there so many barriers between us, always? Barriers of clothing, of etiquette, of time and age and reason.
Surveying the way viruses have been discovered in the past, I came to the conclusion that I could use my technology that I developed as a graduate student - DNA microarray technology - to create a chip that would simultaneously screen for all viruses ever discovered, and furthermore have the built-in capability of discovering new viruses.
Secrecy sets barriers between men, but at the same time offers the seductive temptation to break through the barriers by gossip or confession.
A new species develops if a population which has become geographically isolated from its parental species acquires during this period of isolation characters which promote or guarantee reproductive isolation when the external barriers break down.
As Darwin himself was at pains to point out, natural selection is all about differential survival within species, not between them.
Concord, solidarity, and mutual help are the most important means of enabling animal species to survive.
To conquer nature is, in effect, to remove all natural barriers and human norms and to substitute artificial, fabricated equivalents for natural processes.
