With the global population of humans currently approaching seven billion, it is difficult to imagine that Homo sapiens was once an endangered species. Yet studies of the DNA of modern-day people indicate that, once upon a time, our ancestors did in fact undergo a dramatic population decline. ...
We propose that this is due to its belonging to an early modern human lineage whose morphology differs slightly from present-day humans. We also explore different hypotheses about the presence of this anatomically modern neonate ilium among Neanderthal remains....
In addition, this procedure has the effect of making it difficult to identify damaged molecules which are a strong indicator that those molecules indeed are ancient and not derived from some potential contaminating modern human source. (b) Sequences may be aligned to different human reference ...
For the last few years the genetic advances in the developing field of biotechnology(生物技术) have provides material for all kinds of work but the developments of modern science in unlocking the secrets of the human genetic code have opened a world of possibilities for human health as well as...

human, reinforces a few common misconceptions. One is that there was a simple progression from more “primitive” forms to more “advanced” forms, with modern humans at the pinnacle of evolution; another is that there was only one species or type of early human ar...
The media and scientific literature are increasingly reporting an escalation of large carnivore attacks on humans in North America and Europe. Although rare compared to human fatalities by other wildlife, the media often overplay large carnivore attacks
Indeed, while genetic drift may be one of the primary evolutionary modes of differentiation in modern human populations, gene flow is an important factor that can act to reduce diversity among populations. Gene flow between populations increases their similarity via the exchange and mating of individu...
