#hierarchical classification

Evolution notebook doodles!! Brought to you by “the lecture is long and chemistry takes me longer”

Also this is Hank Teal, he is a plushie I got from Target last week and I love him lol he’s so soft

and e.g. with geology – terms like 'schistose' are reasonably well known but you don't know its comparative equivalents. on a (theoretical) site with hierarchical descriptors, you'd nest:

schistose < coarse-grained foliated metamorphic rock fabrics (schistose, gneissic) < foliated metamorphic rock fabrics (coarse, fine) < metamorphic rock secondary fabrics (foliated, non-foliated) < metamorphic rock fabrics (primary, secondary)

while pencil cleavage would be:

pencil cleavage < fine-grained foliated metamorphic rock fabrics (pencil, slaty, crenulation, phyllitic) < foliated metamorphic rock fabrics (coarse, fine) < metamorphic rock secondary fabrics (foliated, non-foliated) < metamorphic rock fabrics (primary, secondary)
