Scientists agree that Krapina prehistoric man represents the progressive following in the evolution of modern man. Kramberger himself at the beginning of this century compared this collection to some other rich osteological collections of the world, and linked the anatomy of the Krapina neanderthals with modern man. The discovery in Krapina was a proof that the fossil man really did exist, and that the remains found do not belong to some pathological creatures, but normal individuals.

The Krapina proto-human, judging from its anatomy, was probably robust-built - which is also the reflection of their way of life. It is considered that he lived a nomadic life, constantly searching for food and shelter. The cave was used as his habitat, indications of which are the layers of ashes found in the deposits. He used fire, and knew how to make primitive tools from stone used in everyday life. His stone tools are mostly crude, shaped as a knife or scratching tools, made mostly from river stones found around the cave. They are typical of the Mousterian culture. Besides stone, he also used bone tools. It's considered that his average height was approximatly 160 cm, deducted from the studies of the various limb bones.
