Technical issues, such as the level of Neanderthal sequence coverage that can realistically be obtained from a single specimen and the presence of modern human contaminating sequences, reduce the detection of authentic human–Neanderthal sequence differences but may be remedied by methodological improvements.
More critical for the utility of a Neanderthal genome sequence is the evolutionary relationship of humans and Neanderthals.
Renfrew (1973) called it 'the radiocarbon revolution' in describing its impact upon the human sciences.
Oakley (1979) suggested its development meant an almost complete re-writing of the evolution and cultural emergence of the human species.
Humans possess unique physical and cognitive characteristics relative to other primates.
Comparative analyses of the human and chimpanzee genomes are beginning to reveal sequence changes on the human lineage that may have contributed to the evolution of human traits.
Nyerup's words illustrate poignantly the critical power and importance of dating; to order time.
They are the lungs of the world, breathing in carbon dioxide and breathing out the oxygen on which animal life depends.
They live in all sorts of conditions too: in temperate and tropical areas and in arid locations, from mountain landscapes to the rainforests of the equator and the temperate uplands of Scandinavia, they are everywhere.
