A study of 8,300-year-old Jomon human remains in Japan using complete mitogenome sequences obtained by next-generation sequencing.
Authors: Mizuno F, Taniguchi Y, Kondo O, Hayashi M, Kurosaki K, Ueda S Abstract Ancient human remains have been assigned to their mitochondrial DNA (mtDNA) haplogroups. To obtain efficiently deep and reliable nucleotide sequences of ancient DNA of interest, we achieved target enrichment followed by next-generation sequencing (NGS). Complete mitochondrial genome (mitogenome) sequences were obtained for three human remains from the Iyai rock-shelter site of the Initial Jomon Period in Japan. All the Jomon mitogenomes belong to haplogroup N9b, but no sequences among them were identical. High genetic diversity was clar...

How can two biological variables have opposing secular trends, yet be positively related? A demonstration using timing of puberty and adult height.
Authors: Mansukoski L, Johnson W Abstract Timing of puberty and adult height have opposing secular trends yet are positively associated in individuals. We demonstrate this using data from a single sample and discuss possible statistical and epidemiological reasons behind it. The sample comprised 365 females from Fels Longitudinal Study born 1929-1992. We used Super-Imposition by Translation and Rotation (SITAR) to estimate individual age at peak height velocity (PHV) and PHV from serial height data (8149 observations between 5-24 years). General linear regression was used to investigate the association between heig...

Paternal heritage of the Han Chinese in Henan province (Central China): high diversity and evidence of in situ Neolithic expansions.
Conclusion: We suggest that the high genetic diversity in the paternal gene pool of modern Han populations is mainly attributed to the reservation of a larger number of lineages that diverged in the Palaeolithic Age, while the recent expansion of limited lineages contributed to the majority of the gene pool of modern Han populations. We propose that such a structure is a basal characteristic for the genetic structure of modern Han populations. PMID: 32281408 [PubMed - as supplied by publisher] (Source: Annals of Human Biology)
