Homo sapiens — en vetenskaplig kulturkrock
Kulturella Perspektiv, 2000 The completion of the HUGO-project will in a dramatic way alter basic research in all areas of biology. The use of the new information will be facilitated by emergence of bioinformatic and technical development for studies of all genes, which are ...

Analysis of Treacher Collins syndrome 4‐associated mutations in Schizosaccharomyces pombe
FEBS Open Bio, EarlyView.Fission yeast models carrying Treacher Collins syndrome type 4‐associated mutations reveal that impaired processivity of RNA polymerase I leads to defective rRNA transcription. This study highlights the essential role of a conserved arginine residue in Pol I elongation and provides mechanistic insight into the pathogenesis of ribosomopathies.

Del homo economicus al Homo Sapiens
Thēmis, 2010 En este trabajo, Thaler hace diez predicciones sobre el futuro de la Economía. Futuro en el que, nos dice el autor, se hace cada vez más claro aquello que quizás siempre supimos: los hombres no somos completamente racionales, nuestra especie no es la del

Nubian Levallois technology associated with southernmost Neanderthals
Scientific Reports, 2021 Neanderthals occurred widely across north Eurasian landscapes, but between ~ 70 and 50 thousand years ago (ka) they expanded southwards into the Levant, which had previously been inhabited by Homo sapiens. Palaeoanthropological research in the first half

Homo Sapiens: Are We a Monogamous Species? [PDF]
, 2003 In order for the process of hominization to continue, with its prolonged and extreme period of juvenile defencelessness, it was necessary, or at least convenient, for males to more actively participate in the care of females and offspring. This necessity,

Scientific Reports, 2019 Africa was the birth-place of Homo sapiens and has the earliest evidence for symbolic behaviour and complex technologies. The best-attested early flowering of these distinctive features was in a glacial refuge zone on the southern coast 100–70 ka, with ...

Core promoter short tandem repeats as evolutionary switch codes for primate speciation [PDF]
, 2015 Alteration in gene expression levels underlies many of the phenotypic differences across species. Because of their highly mutable nature, proximity to the +1 transcription start site (TSS), and the emerging evidence of functional impact on gene ...
