The Nature of Words in Human Protolanguages: It's Not a Holophrastic-Atomic Meanings Dichotomy
There is an ongoing debate as to whether the words in early pre-syntactic forms of human language had simple atomic meanings like modern words [4, 5], or whether they were holophr...

Evolution and Complexity: The Double-Edged Sword
We attempt to provide a comprehensive answer to the question of whether, and when, an arrow of complexity emerges in Darwinian evolution. We note that this expression can be interp...

Criteria for Conceptual and Operational Notions of Complexity
While complex systems have been studied now for more than two decades, there still is no agreement on what complexity actually is. This lack of a definition might be a problem when...
