Visual Depictions of Our Evolutionary Past: A Broad Case Study Concerning the Need for Quantitative Methods of Soft Tissue Reconstruction and Art-Science Collaborations

open access: yesFrontiers in Ecology and Evolution, 2021
Flip through scientific textbooks illustrating ideas about human evolution or visit any number of museums of natural history and you will notice an abundance of reconstructions attempting to depict the appearance of ancient hominins.

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.

Fossil skulls reveal that blood flow rate to the brain increased faster than brain volume during human evolution [PDF]

open access: yesRoyal Society Open Science, 2016
The evolution of human cognition has been inferred from anthropological discoveries and estimates of brain size from fossil skulls. A more direct measure of cognition would be cerebral metabolic rate, which is proportional to cerebral blood flow rate ...

Earliest archaeological evidence of persistent hominin carnivory. [PDF]

open access: yesPLoS ONE, 2013
The emergence of lithic technology by ≈ 2.6 million years ago (Ma) is often interpreted as a correlate of increasingly recurrent hominin acquisition and consumption of animal remains.

Language evolution to revolution: the leap from rich-vocabulary non-recursive communication system to recursive language 70,000 years ago was associated with acquisition of a novel component of imagination, called Prefrontal Synthesis, enabled by a mutation that slowed down the prefrontal cortex maturation simultaneously in two or more children – the Romulus and Remus hypothesis [PDF]

open access: yesResearch Ideas and Outcomes, 2019
There is an overwhelming archeological and genetic evidence that modern speech apparatus was acquired by hominins by 600,000 years ago. On the other hand, artifacts signifying modern imagination, such as (1) composite figurative arts, (2) bone needles ...

Immature remains and the first partial skeleton of a juvenile Homo naledi, a late Middle Pleistocene hominin from South Africa.

open access: yesPLoS ONE, 2020
Immature remains are critical for understanding maturational processes in hominin species as well as for interpreting changes in ontogenetic development in hominin evolution.

Early human speciation, brain expansion and dispersal influenced by African climate pulses. [PDF]

open access: yesPLoS ONE, 2013
Early human evolution is characterised by pulsed speciation and dispersal events that cannot be explained fully by global or continental paleoclimate records. We propose that the collated record of ephemeral East African Rift System (EARS) lakes could be

Comment définir l’humain à partir de sa diversité ? Questions épistémologiques et enjeux philosophiques

open access: yesBulletins et Mémoires de la Société d’Anthropologie de Paris, 2022
Since 1995, 15 new species have been described in the hominin clade (including all forms closer to extant humans than to extant chimpanzees and bonobos).

When and Why Did Human Brains Decrease in Size? A New Change-Point Analysis and Insights From Brain Evolution in Ants

open access: yesFrontiers in Ecology and Evolution, 2021
Human brain size nearly quadrupled in the six million years since Homo last shared a common ancestor with chimpanzees, but human brains are thought to have decreased in volume since the end of the last Ice Age.

Homoplasy in the evolution of modern human-like joint proportions in Australopithecus afarensis

open access: yeseLife, 2021
The evolution of bipedalism and reduced reliance on arboreality in hominins resulted in larger lower limb joints relative to the joints of the upper limb. The pattern and timing of this transition, however, remains unresolved.
