Hominin life history: reconstruction and evolution [PDF]

Journal 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 ...

Evolution and function of the hominin forefoot [PDF]

Proceedings of the National Academy of Sciences, 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 ...

The evolution of hominin ontogenies [PDF]

Seminars 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 ...

Cytomegalovirus distribution and evolution in hominines [PDF]

Virus 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]

Royal 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 ...

Evolution of Spinopelvic Alignment in Hominins [PDF]

The Anatomical Record, 2017
ABSTRACTSpinopelvic alignment refers to the interaction between pelvic orientation, spinal curvatures, and the line of gravity. In a healthy modern human, this alignment is characterized by reciprocal curves/orientation of the sacrum, lumbar lordosis, thoracic kyphosis, and cervical lordosis.

Earliest archaeological evidence of persistent hominin carnivory. [PDF]

PLoS 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]

Research 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.

PLoS 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.
