A spring forward for hominin evolution in East Africa. [PDF]

open access: yesPLoS ONE, 2014
Groundwater is essential to modern human survival during drought periods. There is also growing geological evidence of springs associated with stone tools and hominin fossils in the East African Rift System (EARS) during a critical period for hominin ...

Dynamics of green Sahara periods and their role in hominin evolution. [PDF]

open access: yesPLoS ONE, 2013
Astronomically forced insolation changes have driven monsoon dynamics and recurrent humid episodes in North Africa, resulting in green Sahara Periods (GSPs) with savannah expansion throughout most of the desert.

Modelling the role of groundwater hydro-refugia in East African hominin evolution and dispersal [PDF]

open access: yesNature Communications, 2017
Water is a fundamental resource, but its role in hominin evolution is not well explored. Here, the authors use a combination of groundwater, climate and agent-based models to show that groundwater availability may be critical to past patterns of ...

Evolution and function of the hominin forefoot [PDF]

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2018
Significance A critical step in the evolutionary history leading to the origins of humankind was the adoption of habitual bipedal locomotion by our hominin ancestors. We have identified novel bony shape variables in the forefoot across extant anthropoids and extinct hominins that are linked functionally to the emergence of ...

Measure, Then Show: Grasping Human Evolution Through an Inquiry-Based, Data-driven Hominin Skulls Lab. [PDF]

open access: yesPLoS ONE, 2016
Incomprehension and denial of the theory of evolution among high school students has been observed to also occur when teachers are not equipped to deliver a compelling case also for human evolution based on fossil evidence.

Hominin life history: reconstruction and evolution [PDF]

open access: yesJournal of Anatomy, 2008
AbstractIn this review we attempt to reconstruct the evolutionary history of hominin life history from extant and fossil evidence. We utilize demographic life history theory and distinguish life history variables, traits such as weaning, age at sexual maturity, and life span, from life history‐related variables such as body mass, brain growth, and ...

Meaning-making behavior in a small-brained hominin, Homo naledi, from the late Pleistocene: contexts and evolutionary implications [PDF]

open access: yeseLife
Explorations in the Dinaledi Subsystem of the Rising Star cave system have yielded some of the earliest evidence of a mortuary practice in hominins. Because the evidence is attributable to the small-brained Homo naledi, these analyses call into question ...

Loss of olfactory receptor function in hominin evolution. [PDF]

open access: yesPLoS ONE, 2014
The mammalian sense of smell is governed by the largest gene family, which encodes the olfactory receptors (ORs). The gain and loss of OR genes is typically correlated with adaptations to various ecological niches. Modern humans have 853 OR genes but 55%

Cytomegalovirus distribution and evolution in hominines [PDF]

open access: yesVirus Evolution, 2019
Abstract Herpesviruses are thought to have evolved in very close association with their hosts. This is notably the case for cytomegaloviruses (CMVs; genus Cytomegalovirus) infecting primates, which exhibit a strong signal of co-divergence with their hosts. Some herpesviruses are however known to have crossed species barriers.

The evolution of hominin ontogenies [PDF]

open access: yesSeminars in Cell & Developmental Biology, 2010
Since the beginnings of paleoanthropology, immature fossil hominin specimens have marked important but highly contested cornerstones of research. Long deemed as not representative of a fossil species’ morphology, immature hominins are now in the center of scientific attention, and an increasing interest in evolutionary developmental questions has made ...
