Natural history of the ERVWE1 endogenous retroviral locus

open access: yesRetrovirology, 2005
Background The human HERV-W multicopy family includes a unique proviral locus, termed ERVWE1, whose full-length envelope ORF was preserved through evolution by the action of a selective pressure. The encoded Env protein (Syncytin) is involved in hominoid

A novel attention-getting vocalization in zoo-housed western gorillas.

open access: yesPLoS ONE, 2022
As a critical aspect of language, vocal learning is extremely rare in animals, having only been described in a few distantly related species. New evidence, however, extends vocal learning/innovation to the primate order, with zoo-housed chimpanzees and ...

Structural Characterization of the Highly Restricted Down Syndrome Critical Region on 21q22.13: New KCNJ6 and DSCR4 Transcript Isoforms

open access: yesFrontiers in Genetics, 2021
Down syndrome (DS) is caused by trisomy of chromosome 21 and it is the most common genetic cause of intellectual disability (ID) in humans. Subjects with DS show a typical phenotype marked by facial dysmorphisms and ID.

The biomechanical importance of the scaphoid-centrale fusion during simulated knuckle-walking and its implications for human locomotor evolution [PDF]

open access: yes, 2020
© 2020, The Author(s). Inferring the locomotor behaviour of the last common ancestor (LCA) of humans and African apes is still a divisive issue. An African great-ape-like ancestor using knuckle-walking is still the most parsimonious hypothesis for the ...

Dental functional morphology predicts the scaling of chewing rate in mammals [PDF]

open access: yes, 2018
How food intake and mastication scale to satisfy the metabolic needs of mammals has been the subject of considerable scientific debate. Existing theory suggests that the negative allometric scaling of metabolic rate with body mass is compensated by a ...

On the origins of Mendelian disease genes in man: the impact of gene duplication [PDF]

open access: yes, 2011
Over 3,000 human diseases are known to be linked to heritable genetic variation, mapping to over 1,700 unique genes. Dating of the evolutionary age of these disease-associated genes has suggested that they have a tendency to be ancient, specifically ...

On the origin and evolutionary history of NANOG. [PDF]

open access: yesPLoS ONE, 2014
Though pluripotency is well characterized in mammals, many questions remain to be resolved regarding its evolutionary history. A necessary prerequisite for addressing this issue is to determine the phylogenetic distributions and orthology relationships ...

EVOLUTION OF THE HUMAN CAPACITY FOR BELIEFS

open access: yesZygon, 1993
. Evolution of the human capacity for beliefs is considered in relation to the emergence in human phylogeny of the ability to formulate propositions, evaluate their worth as bases for action, and make emotional attachments to them.

Elucidation of cross-species proteomic effects in human and hominin bone proteome identification through a bioinformatics experiment

open access: yesBMC Evolutionary Biology, 2018
Background The study of ancient protein sequences is increasingly focused on the analysis of older samples, including those of ancient hominins. The analysis of such ancient proteomes thereby potentially suffers from “cross-species proteomic effects ...
