Question

a scientist creates a diagram that sorts organisms based on their observed traits. they are creating a(n) select transitional fossil. lineage. cladogram. taxon.

Explanation:

A diagram that classifies organisms by shared observable traits, showing evolutionary relationships through branching, is defined as a cladogram. The other options do not match: transitional fossils are fossilized organisms with intermediate traits, a lineage is a sequence of ancestral/descendant organisms, and a taxon is a named group of organisms.

Answer:

cladogram.
