basaler

Basaler is a term found chiefly in German-language scientific and academic writing, where it functions as the comparative form of the adjective basal (or basale). It denotes that something is more basal, meaning it is situated toward the base of a structure or more closely related to the base in an evolutionary sense. The root is the Latin-based bas-, from basis, meaning base or foundation.

In biology and paleontology, basaler is occasionally used to describe features, taxa, or positions that are closer to the base of a phylogenetic tree or closer to ancestral conditions compared with more derived forms. In botany or anatomy, basale or basaler can describe structures located at the base of an organ or organism; for instance, the basale layer of the epidermis.

In English-language usage, the corresponding term is basal, and the comparative is more basal, not a common standalone form. German and some other languages maintain basaler as part of standard scientific phrasing, though the exact usage can vary by field.
