In 1912 he painted Flowering Apple Tree, a richly branching diagram
through which pale leaf-shapes flow.
These five independent variables were then represented on a branching diagram
(Fig.1 below) following the particular order in which a variable occurs.
Evolutionary trees, branching diagrams
that often look like a cross between a candelabra and a subway map, aren't just for figuring out whether aardvarks are more closely related to moles or manatees, or pinpointing a slime mold's closest cousins.
There, the separate drawings and sculptures coalesced into a delicate Gesamtkunstwerk amid a fractured white crystalline landscape in which models of constellations and spheres, refractions, and branching diagrams
of trees merged into an almost otherworldly panorama atop their pedestals.
"If you visualize evolutionary relationships in the form of branching diagrams
and then plot them on a time scale, new patterns begin to emerge, with gaps in the fossil record suddenly filling rapidly," Ruta stated.
The problem of partial phylogeny was well analyzed by these authors: branching diagrams
for relations between the parts of organisms (partial phylogenies) can be depicted independent of any full phylogeny that attempts to show the evolutionary history of the entire population or species of organism in question.
