As only limited insight into behaviour is available from the archaeological record, much of our understanding of historical changes in human cognition is restricted to identifying changes in brain size and architecture. Using both absolute and residual brain size estimates, we show that hominin brain evolution was likely to be the result of a mix of processes; punctuated changes at approximately 100 kya, 1 Mya and 1.8 Mya are supplemented by gradual within-lineage changes in Homo erectus and…

Pattern and process in hominin brain size evolution are scale-dependent
A reliable proxy for brain size in fossils, endocranial volume (ECV), is used to better understand how brain size evolved at both clade- and lineage-level scales and provides a quantitative basis for developing and testing scale-explicit hypotheses about the factors that led brain size to increase during hominin evolution.
A synthesis of the theories and concepts of early human evolution
The pulsed climate variability hypothesis suggests the long-term drying trend in East Africa was punctuated by episodes of short alternating periods of extreme humidity and aridity which may have driven hominin speciation, encephalization and dispersals out of Africa.
Early Human Speciation, Brain Expansion and Dispersal Influenced by African Climate Pulses
It is proposed that the collated record of ephemeral East African Rift System (EARS) lakes could be a proxy for the regional paleoclimate conditions experienced by early hominins, and Plio-Pleistocene East African climate pulses as evinced by the paleo-lake records seem fundamental to hominin speciation, encephalisation and migration.

Different environmental variables predict body and brain size evolution in Homo
Temperature is identified as a major predictor of body size variation within Homo, in accordance with Bergmann’s rule, and net primary productivity of environments and long-term variability in precipitation correlate with brain size but explain low amounts of the observed variation.
Pattern and rate in the Plio-Pleistocene evolution of modern human brain size
Fourteen studies of brain size evolution in Plio-Pleistocene hominins published over the past fifty years show substantial long-term increase in endocranial volume (ECV) for the broad lineage leading

Oceans and seas are more frequently thought to have been barriers to than enablers of movement for archaic hominins. This interpretation has been challenged by a revisionist model which suggests that
Paleoneurology and Behaviour
This chapter examines some inferences that can be made about the origins of language based on paleoneurological and archaeological evidence, and focuses on laterality as a case study for the many behaviours that could be inferred from archaeology, and which are relevant to the origins and evolution of language.

Long-term patterns of body mass and stature evolution within the hominin lineage
Combined taxonomic and temporal analyses show that in relation to australopithecines, early Homo is characterized by significantly larger average body mass and stature but retains considerable diversity, including small body sizes.


Environmental hypotheses of hominin evolution.

Several environmental hypotheses of human evolution are presented and it is shown that the variability selection hypothesis is strongly supported by the persistence of hominins through long sequences of environmental remodeling and the origin of important adaptations in periods of wide habitat diversity.
Hominid Brain Evolution
Although the effects of paleoclimatic variability and temperature variation provide support for climatic hypotheses, the proxy for population density predicted more unique variance in CC than all other variables and suggests multiple pressures drove hominid brain evolution and that the core selective force was social competition.
Variability selection in hominid evolution
If some complex traits indeed require disparities in adaptive setting (and relative fitness) in order to evolve, the VS idea counters the prevailing view that adaptive change necessitates long‐term, directional consistency in selection.
Encephalization is not a universal macroevolutionary phenomenon in mammals but is associated with sociality
It is shown that there is wide variation across groups in encephalization slopes across groups and that encephalizations is not universal in mammals, and it is found that temporal changes in brain size are not associated with allometric relationships between brain and body size.
Hominid Brain Evolution Testing Climatic , Ecological , and Social Competition Models
Hypotheses regarding the selective pressures driving the threefold increase in the size of the hominid brain since Homo habilis include climatic conditions, ecological demands, and social

It is apparent that the (significant) increase in volume documented for the Middle Pleistocene individuals is not simply a consequence of larger body mass, and Encephalization quotient values confirm this finding.
Anatomy, behavior, and modern human origins
The fossil record suggests that modern human morphology evolved in Africa between 150,000 and 50,000 years ago, when the sole inhabitants of Eurasia were the Neanderthals and other equally nonmodern
Paleoclimatic Variation and Brain Expansion during Human Evolution
Based on a sample of 109 fossilized hominid skulls, it is found that cranial capacities were highly correlated with paleoclimatic changes in temperature, as indexed by oxygen isotope data and sea-surface temperature.
The pattern of evolution in Pleistocene human brain size
The analyses do not reject the hypothesis of a single process of brain size change, but they are incompatible with an interpretation of punctuated equilibrium during this period and the results are difficult to reconcile with the case for cladogenesis in the Homo lineage during the Pleistocene.

The underlying model that is developed is that the evolution of ‘human society’ is underpinned by ecological factors, but these are influenced as much by technological and behavioural innovations as external environmental change.
