Were Neanderthals the first humans to bury their dead?

The Contribution of Neanderthals to Phenotypic Variation in Modern Humans

Assessing the genetic contribution of Neanderthals to non-disease phenotypes in modern humans has been difficult because of the absence of large cohorts for which common phenotype information is available. Using baseline phenotypes collected for 112,000 individuals by the UK Biobank, we can now elaborate on previous findings that identified associations between signatures of positive selection ...

When Did Neanderthals and Modern Humans Diverge?

The availability of sequences from the mtDNA hypervariable region I and II of a specimen of the Neanderthal,1,2 Homo neanderthalensis, permits estimation of the time of divergence of Neanderthals and modern humans. Based on substitution rates derived from comparison of human and chimpanzee, Krings et al. provided an estimate of 550–690 KY1 and 317–741 KY2 before present for the split between th...

Facial ontogeny in Neanderthals and modern humans.

One hundred and fifty years after the discovery of Neanderthals, it is held that this morphologically and genetically distinct human species does not differ from modern Homo sapiens in its craniofacial ontogenetic trajectory after the early post-natal period. This is striking given the evident morphological differences between these species, since it implies that all of the major differences ar...

Effective Factors on the Decision of Families to Donate the Organs of their Brain Dead Relatives

Background & Aims: At present due to brain dead patients’ families refuse to organ donation, the number of available organs is less than the requesting cases. The aim of this comparative descriptive study was to compare opinions of donor and nondonor families about relevant factors in their decision making. Methods: participants included 175 members of 71 families (141 members of 56 donor famil...
