almost 50% of our current DNA is because of viruses
where did you get this number?
and what does your statement mean? because of viruses...
I read it somewhere on a medical board somewhere, can't remember now, posted it a while ago when all this crap first started. The "because of viruses" means that they forced a lot of biological changes in us to become more resistant to them. Our bodies learn, each part can learn as we go through life, our immune system needs to practice to, thus why colds and flus are important, because we can survive those without medical attention. Each time we get sick from viruses our body learns how to fight them off better, thus why you really can't get the same cold or flu twice, unless you get the vaccine, in which case your body doesn't learn as much since it's already dead. Each time you get the cold or flu it's a different virus.
