Native American Genomic Diversity through Ancient DNA

Detection of Cytosine Methylation in Ancient DNA from Five Native American Populations Using Bisulfite Sequencing

While cytosine methylation has been widely studied in extant populations, relatively few studies have analyzed methylation in ancient DNA. Most existing studies of epigenetic marks in ancient DNA have inferred patterns of methylation in highly degraded samples using post-mortem damage to cytosines as a proxy for cytosine methylation levels. However, this approach limits the inference of methyla...

Ancient DNA reveals Holocene loss of genetic diversity in a South American rodent.

Understanding how animal populations have evolved in response to palaeoenvironmental conditions is essential for predicting the impact of future environmental change on current biodiversity. Analyses of ancient DNA provide a unique opportunity to track population responses to prehistoric environments. We explored the effects of palaeoenvironmental change on the colonial tuco-tuco (Ctenomys soci...

Mitochondrial DNA Diversity of Korean Native Goats

Korean native goats have lived on the Korean peninsula for more than 2,000 years and are regarded as a valuable genetic resource for the world. As an initial step to investigate the genetic structures of this breed, phylogenetic analysis and calculation of genetic diversities have been performed using mitochondrial DNA (mtDNA) sequence variations. A total of 19 Korean native goats were grouped ...

Enterobius vermicularis: Ancient DNA from North and South American Coprolites

Ancient DNA from Human and Animal

Research on ancient DNA (aDNA) has the potential to enable molecular biologists and archeologists to decipher certain aspects of history by direct looking into the past. However, several major problems in this field limit the applicability of aDNA studies, most importantly contamination with modern DNA and postmortem DNA degradation. In this study we extracted and analyzed aDNA obtained from ~3...
