Paleogenomics of Archaic Hominins
In order to understand the genetic basis for the evolutionary success of modern humans, it is necessary to compare their genetic makeup to that of closely related species. Unfortunately, our closest living relatives, the chimpanzees, are evolutionarily quite distant. With the advent of ancient DNA study and more recently paleogenomics - the study of the genomes of ancient organisms - it has bec...
متن کاملThe Archaic Maternal Superego

The sense in which I employ the term here is to designate a set of problems which are both clinical and theoretical, not the name for a supposed metapsychological agency whose theoretical necessity would be questionable...
متن کاملTwo Greek siblings with sepiapterin reductase deficiency.

METHODS We describe the clinical history and extensive cerebrospinal fluid (CSF) and urine examination of two Greek siblings with the diagnosis of SR deficiency.

متن کاملTwo Remarks on Ancient Greek Geometry
Modern physical theories tell us that space is not euclidean. Yet, to most people, euclidean geometry seems most natural. Furthermore, most mathematical theories of non-euclidean geometry refer back to euclidean geometry in one way or another. For example, in differential geometry, the differential areas are almost always approximately Euclidean. Why is this? I want to suggest here a reason roo...
متن کاملArchaic admixture in human history.
Modern humans evolved in Southern or Eastern Africa, and spread from there across the rest of the world. As they expanded across Africa and Eurasia, they encountered other hominin groups. The extent to which modern and 'archaic' human groups interbred is an area of active research, and while we know that modern humans interbred with Neanderthals and Denisovans, there is not yet agreement on how...
