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

PLoS 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

Brain enlargement and dental reduction were not linked in hominin evolution. [PDF]

Proc Natl Acad Sci U S A, 2017
The large brain and small postcanine teeth of modern humans are among our most distinctive features, and trends in their evolution are well studied within the hominin clade.

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

Bulletins 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).

Archaeogenomic insights into the adaptation of plants to the human environment : pushing plant–hominin co-evolution back to the Pliocene [PDF]

, 2015
The colonization of the human environment by plants, and the consequent evolution of domesticated forms is increasingly being viewed as a co-evolutionary plant–human process that occurred over a long time period, with evidence for the co-evolutionary ...

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

eLife, 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.

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

Frontiers 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.

Understanding Paleoclimate and Human Evolution Through the Hominin Sites and Paleolakes Drilling Project [PDF]

Scientific Drilling, 2009
Understanding the evolution of humans and our close relatives is one of the enduring scientific issues of modern times. Since the time of Charles Darwin, scientists have speculated on how and when we evolved and what conditions drove this evolutionary ...

Comment la connaissance de la diversité posturo-locomotrice des primates a-t-elle transformé la compréhension de celle des hominines ?

Revue de Primatologie, 2022
In recent decades, the way paleoanthropologists conceive of bipedalism has changed considerably. If bipedalism was once thought to be a unique characteristic, specific to the hominin lineage and marking its origin, the hypothesis of its anatomical and ...

Using strontium isotopes to determine philopatry and dispersal in primates: a case study from Kibale National Park [PDF]

Royal Society Open Science, 2021
Strontium isotope ratios (87Sr/86Sr) allow researchers to track changes in mobility throughout an animal's life and could theoretically be used to reconstruct sex-biases in philopatry and dispersal patterns in primates.
