Modern humans genetically proven to have serious attention based on cerebellum feedback focus!

 Lombard identified 180 genes associated with attention in Homo sapiens that differ from those in Neanderthals and Denisovans. Eighteen were highly expressed in specific brain regions, including the brainstem, cerebellum, amygdala, basal ganglia, white matter, and thalamus. Many of these regions are typically considered “ancient” brain structures, not the obvious centers of higher cognition. “These subcortical regions, along with the thalamus, are implicated in the evolution of human attention and deserve more focused study,” Lombard argues.


 This is the SECRET of what makes modern humans different than Neanderthals or Denisovans! Wow.

  direct genetic influences cannot be ruled out. Based on their genetic archaeology of human cognitive traits, Kaczanowska et al. (2022) suggest that adaptive evolution associated with excitatory neurons and synaptic function, shifted from functional networks for motor control to attention in ancient hominoids by > 19 Ma and hominids by > 7.4 Ma. After our split from the great apes >5 Ma, the hominin ability to control attention continued to go through wide-ranging changes, with extinct hominins likely evolving quantitatively and qualitatively different permutations (Bruner and Colom, 2022; Bruner, 2024). According to Bruner (2024: 7) the complex socio-technical networks “of the genus Homo (especially in H. sapiens) are not possible without an attentional system”.
