In this paper, we examine a case of scientific controversy over the evolving role of the paranasal sinuses, comparing Neanderthals and humans by analyzing two rival hypotheses. The first hypothesis states that the paranasal sinuses do not represent an adaptation to extreme cold, while the second claims the contrary. The two articles partially use the same database and employ identical methodologies and evolutionary examples of evolutionary adaptation in humans assumptions.

Our paper highlights the misunderstandings that can arise when an attempt is made to analyze a complex structure from an evolutionary perspective using two-dimensional analytical techniques, that is to say, explaining a trait in isolation and, consequently, losing an integrated approach to the organism and its multiple interactions with the environment. Key words: Scientific controversy, paranasal sinuses, Neanderthals, humans, complex systems, modularity, controversial spaces, methodologies, evolutionary explanations, philosophy of biology.

Homologous chromosomes chromosome pairs of the same length, centromere position, and staining pattern, with genes for the same characteristics at corresponding loci. Our results, including several complementary approaches, confirm the strong selection pressure that the antimicrobial effect of sulfite imposes on yeasts in human-driven fermentations, as well as remarks on the role of chromosomal rearrangements as a source evolutoinary variation to promote yeast adaptations in fast-evolving environments.
