"Homo informatio" v2

Highlights/Short Abstract1. A broader cognitive zone of bounded surprisal (ZBS) emerged during Late Miocene times in small social units of mosaic-landscape dwelling homininans than in woodland-dwelling paninans. 2. Small-world homininan networks of small, mixed-sex philopatric, social units, with maternal and paternal close proximity to children, facilitated the augmentation of intra- and inter-unit information.3. Pliocene and Pleistocene spatiotemporal spread of homininans involved increases of transmissible information that expanded tool-making, resource-exploitation, and communicative fluency.4. Biological and natural processes are indicated which could have been advantageous or disadvantageous to the survival of various homininan taxa identified in the Pliocene and Pleistocene fossil record.
