hiv is a darwin's dna? interresting article :)
« on: July 04, 2015, 12:25:26 AM »
research has shown that about eight percent of human genetic material comes from a virus and not from our ancestors, according to researchers in Japan and the U.S.

The genomes of humans and other mammals contain DNA derived from the insertion of bornaviruses, RNA viruses whose replication and transcription takes place in the nucleus. Research led by Professor Keizo Tomonaga at Osaka University in Japan shows virally transmitted DNA may be a cause of mutation and psychiatric disorders such as schizophrenia and mood disorders.
The findings were in an article by University of Texas at Arlington biology professor CÚdric Feschotte in the Jan. 7, 2010 issue of Nature magazine. Feschotte speculates about the role of such viral insertions in causing mutations with evolutionary and medical consequences. The assimilation of viral sequences into the host genome is a process referred to as endogenization, which occurs when viral DNA integrates into a chromosome of reproductive cells and is subsequently passed from parent to offspring.

Until now, retroviruses were the only viruses known to generate such endogenous copies in vertebrates. But Feschotte said that scientists have found that non-retroviral viruses called bornaviruses have been endogenized repeatedly in mammals throughout evolution

Not sure how it really or directly relates to HIV at all.

Anyhow you did not include a link however if I recall the reason CÚdric Feschotte was looking into this was he speculated that in patients with mental illnesses it was related to the viral DNA markers being present, I think it was links between Schizophrenia/Bi-Polar and depression. (I read it at the time as I have a interest with regards to Schizophrenia)

However if I remember correctly studies over the years following concluded no link   and debunked CÚdric's theory's and studies for the most part. That's okay though as you need a good scientific theory before you start trying to prove or dis prove it :-).

I always liked this one: http://phenomena.nationalgeographic.com/2013/01/01/how-a-quarter-of-the-cow-genome-came-from-snakes/

25 % of a cow is the same as a snake, still a cow is a cow and a snake is a snake.

Wish you would post with a links and references hayssam.
(No I'm not looking them up for you)

To quote my sister:
See my theory is dad farted so much near us as kids that he has given me all these deficiencies! So be careful where you fart! 😁
