The Tree of Life

a group at the European Molecular Biology Lab in Heidelberg, Germany has published an improved 'tree' of evolutionary relationships in this week's Science. their genomic analysis reduced noise by excluding from analysis those genes introduced by horizontal gene transfer, a process in which genetic material from a parent is swapped into an organism other than its progeny (this has been hailed as "a new paradigm for evolutionary biology", and is potentially very dangerous). fair enough, this may not have much to do with Christianity, but their new analysis is cool.
