  We expose a new excitation transport channel in FMO, consisting of the 7
intramonomeric pigments and their 2nd nearest intermonomeric counterpart. Such
a channel outcompetes the standard alternative, where intramonomeric pigments
partner with their closest intermonomeric pigment. The efficient performance of
the new channel lies at the interplay between incoherent energy transfer and
the capacity of quantum coherence to build optimal acceptor levels. Finally,
the differential fitness and peculiarity of the new over the alternative
channel highlights its possible role within natural selection.
