Carolus Linnaeus
he placed organisms into groups based on their observable features
Observable characteristics are traits or features that can be easily seen, heard, or detected. These may include physical appearance, behavior, actions, or any other visible attribute that can be perceived by the senses.
In determining the taxon based on morphology, a scientist typically considers observable physical traits and features of organisms to classify them into hierarchical groups. While genetic similarities can provide additional evidence to support taxonomic classification, morphology is the primary basis for assigning organisms to different taxonomic groups.

There are other answers, but here's one: Science is the systematic accummulation of knowledge about the observable world which has features of self-correction to it.
That characteristic is known as an observable attribute. Observable attributes are qualities that can be perceived through the senses, such as color, size, shape, or texture. They serve as key features used to describe and differentiate objects.
