See www.sciencedaily.com/releases/2012/09/120924144751.htm Looking into the article, and other recent research findings http://iopscience.iop.org/0004-637X/754/1/56 "Was The Sun Born In A Massive Cluster? some facts seem significant: the odds of transfer are good in star clusters, and even better in super-clusters; the Sun seems to've been born in a supercluster of many tens of thousands stars (or more): evidenced by our finding heavy elements born in nearby super-novas, plus many meteoritic traces - so the Sun must've had lots of close neighbours in its early life; the over-lapping windows of opportunity for these events - many near neighbours, lots of slow transfer, suitable early Earth conditions (or on other Earthlike planets) all mean that a good deal of mutual transfers could have been of bacteria (including DNA). Many of our Sun's siblings will have dispersed randomly throughout the Galaxy during the 20 to 30 galactic orbits the Sun has made since birth, but there are probably many more still in the vicinity. Recent research has hugely increased the chances of planets, including Earthlike ones, around virtually any star, including double or triple star systems. An obvious conclusion is that there might be many thousands, or hundreds of thousands of life forms in the Galaxy which are DNA related to Earth life, and many won't be very far away.
