Ancient DNA: the first three decades

The First Attested Extraction of Ancient DNA in Legumes (Fabaceae)

Ancient DNA (aDNA) is any DNA extracted from ancient specimens, important for diverse evolutionary researches. The major obstacles in aDNA studies are mutations, contamination and fragmentation. Its studies may be crucial for crop history if integrated with human aDNA research and historical linguistics, both general and relating to agriculture. Legumes (Fabaceae) are one of the richest end eco...

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...

Three Decades of Multiprocessors

During the last 25 years, the author has never reallv considered any alternative to the multiprocessor (mP) for general-purpose, cost-effective, nonminimal come -rs. This involvement with mPs at Digital Equipment Corporation (DEC), Carnegie Mellon University (CMU), Encore, Stardent, and Kendall Square Research (KSR) included 16 computers. Fourteen were built, including 7 for research or advance...

Ancient DNA

Ancient DNA is a field of molecular evolutionary biology that usesDNA sequence data recovered frompoorly preserved organisms, usually deceased for hundreds to hundreds of thousands of years. Ancient DNA data can provide unique snapshots in time to better understand how populations and species evolve. The field was born in the early 1980s,when thefirst ancientDNAsequences were recovered from pre...
