Extant transitional species and lineages that bridge major evolutionary steps have been well-documented in various taxa, supporting the occurrence of evolutionary transitions.
The claim posits that living intermediate species exist that bridge major evolutionary transitions. Papers like [1] explicitly identify relict extant species occupying transitional phylogenetic positions between major ant agricultural systems, and paper [3] discusses extant and fossil forms spanning dietary transitions. The retrieved literature clearly supports the existence of transitional taxa. Therefore, the balance verdict is SUPPORTED.
