It is not yet clear if any of the traits of the aforementioned adaptive complex were significant to the origin of the genus Homo, but that does not diminish the evidence or weaken the case for its start at the end of the Pliocene (Kimbel 2009).
In one significant example, the origin of the HIV pandemic was investigated by comparing the patristic distances of dated HIV gene sequences [ 5].
Only a processive polymerase is significant for the origin of the first genetic system because a number of molecules with polymerase properties can't arise simultaneously.
Discovery of such a low flux and highly absorbed X-ray source could have a significant impact on the origin of the cosmic X-ray background.
The study of the nuclear pore complex (NPC) is a fascinating endeavor, as it not only implies uncovering the 'engineering marvel' of its architecture and function, but also provides a key window into a significant evolutionary event: the origin of the eukaryotic cell.
The other significant theory about the origin of the legend, proposed by Robert Chambers in 1864, is that a genuine child was born in the early 17th century with facial deformities resembling a pig's face and a speech impediment causing her to grunt.
The presence of four sacrals (DS+S1+S2+CS) in Leonerasaurus, coupled with its smaller body size and its position as the sister group of the large bodied clade of Melanorosaurus+Sauropoda, is highly significant for understanding the origin of the sauropod-type sacrum.
However, none of the nucleotides and derivatives that we detected (nor overall protein) displayed a significant reduction, leaving the origin of the uric acid unclear.
We found no significant effects of parental origin of the 22q11.2 deletion, deletion length, paternal age or family history of psychotic illness on developing schizophrenia in 22q11.2DS.
There were no significant effects of parental origin of the 22q11.2 deletion, deletion length, parental age or family history on expression of schizophrenia.
