"The researchers used a radioactive tracer to be sure that the slugs are actually producing the chlorophyll themselves, as opposed to just stealing the ready-made pigment from algae. In fact, the slugs incorporate the genetic material so well, they pass it on to further generations of slugs."<p>That is simply mind blowing. So essentially the case is made that DNA that you <i>eat</i> ends up in your genetic lineage ?!<p>That means that there might be serious repercussions from ingesting genetic material.<p>I find that in some way bigger news than the slug that does photosynthesis, mind boggling as it is.
