First Evidence of Horizontal DNA Transfer From Parasite to Host

 

The first real evidence of horizontal transfer of specific DNA segments called transposons has been obtained by genome biologist Cédric Feschotte and postdoctoral researchers Clément Gilbert and Sarah Schaack. The findings will be published in the journal Nature.

Transposons are pieces of DNA that can replicate and change position within a genome, indicating that these horizontal transfers could have had potentially dramatic impacts on the evolution of many species, including mammals...and us.

The effects observed between a bug and a snail are intriguing, but how transposons can spread across a broad range of species is still a mystery. Almost half of the human genome is composed of transposons, emphasizing the findings´ potential import.

  I suppose...  
 
...it might look better if Transposon in the title was replaced with DNA. Your call Admin :)

  "including mammals...and us."  
 
the and us isn´t needed as we are mammals.

  So  
 
... DNA from a spider could really be transferred to a young science student, is that what we´re talking about here?

  mitochondrial theories  
 
It was a theory that mitochondria was a form of symbiote with cellular hosts which eventually became inextricably bonded with one-another.

  Are there...  
 
...any nice looking female research scientists who would care to help me in a horizontal DNA transfer experiment? Come on folks, this is science.

(Sorry, I kinda had to since no one else had yet)

(Article is fascinating)
