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...
متن کاملAncient 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...
متن کاملEndemics and adventives: Thysanoptera (Insecta) biodiversity of Norfolk, a tiny Pacific Island.
The thrips fauna of Norfolk Island is a curious mix of endemics and adventives, with notable absences that include one major trophic group. A brief introduction is provided to the history of human settlement and its ecological impact on this tiny land mass in the western Pacific Ocean. The Thysanoptera fauna comprises about 20% endemic and almost 50% widespread invasive species, and shows limit...
متن کاملRodent eradication on Lord Howe Island: challenges posed by people, livestock, and threatened endemics
Like many oceanic islands, World Heritage listed Lord Howe Island (LHI), 760 km north-east of Sydney (Australia), has populations of invasive rodents. The house mouse (Mus musculus) probably arrived around 1860, and the ship rat (Rattus rattus) in 1918. Both species have significantly reduced the island’s biodiversity. Rats are implicated in the extinction of at least 20 species (or subspecies)...
متن کاملAncient DNA and human history.
We review studies of genomic data obtained by sequencing hominin fossils with particular emphasis on the unique information that ancient DNA (aDNA) can provide about the demographic history of humans and our closest relatives. We concentrate on nuclear genomic sequences that have been published in the past few years. In many cases, particularly in the Arctic, the Americas, and Europe, aDNA has ...
