Every time I find interesting (and frighting) that we are nothing but a collection of ourselves and virus and bacterias, written down to our DNA and RNA or living together with close dependence deep in our guts (literally).

Going further, a lot of what we do unconciously is just what a virus or something else "did" to survive or spread in the past, and our free will isn't that free...

Edit: "did" wasn't meaning that a specific goal was set, for example, but just that the survival rate was better for certain configuration of atoms

It's also revealing how the unique ability of humans to overcome their fundamental biological nature can be quite impressive and inspiring. Humans have many natural tendencies that are not socially accepted, and better behavior can be learned and tendencies suppressed. Addicts and alcoholics can turn their lives around, even though they remain addicts for life.

That ability is itself part of the fundamental biological nature of humans, or whatever. The way you phrased it suggests a Cartesian dualistic interpretation.

Human Endogenous Retrovirus-K HML-2 integration within RASGRF2 is associated with intravenous drug abuse and modulates transcription in a cell-line model

Not all humans have the same HK2 viruses in their genomes. Here we show that one specific uncommon HK2, which lies close to a gene involved in dopaminergic activity in the brain, is more frequently found in drug addicts and thus is significantly associated with addiction. We experimentally show that HK2 can manipulate nearby genes. Our study provides strong evidence that uncommon HK2 can be responsible for unappreciated pathogenic burden, and thus underlines the health importance of exploring the phenotypic roles of young, insertionally polymorphic HK2 integrations in human populations.

...

Based on our cell-line experiments, we suggest that RASGRF2-int leads to enhancement of dopaminergic activity through higher expression of the first exons of RASGRF2, which then results in increased potential for addiction.

I have some bad news for you: your perception of free will is a by-product of your ignorance of how your brain works. Every decision you think you make is actually just a bunch of neurons firing, and those neurons were built by your DNA.

No one actually believes this, including you. You may say you do, and even think you do, but you don’t. Everyone acts as if they and others around them possess free will. We act that way because that’s what we believe.

Honestly, I don’t think we understand enough about consciousness and how it arises from physical brains/bodies to make such an extraordinary claim like “there is no free will,” when the entire history of human thought and philosophy presupposes that there is.

Does this mean you could be tested for the specific gene?

They don't actually believe it. Deterministic processes in their brain are making them THINK they believe it.

About 20% of the human genome is endogenous retroviruses. We've all got them, and there is significant evidence that they become more active in old age, and may be a factor in dementia and other illnesses.
