A new article published in the journal Scientific Reports reveals 44% of the colonies of Didemnum vexillum—a marine invertebrate tagged as invasive species—in the Ebro Delta (Tarragona, Spain) are formed by gene chimera: that is, cells with a different gene pool. According to the study, this ability to create chimera could be a determining factor in promoting genetic diversity and the colonizing success of this exotic species in natural ecosystems worldwide.
