Archaeobotany: Macroremains
Palaeoethnobotany (or the shorter term, archaeobotany) is the study of the "direct interrelationships between humans and plants for whatever purpose as manifested in the archaeological record."50 No matter what the time period or geographical area, plants played an important role in human culture. As primary data about the natural environment, landuse practices, diet, architecture, and trade in...
متن کاملAncient 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 کاملAdvances in ancient DNA studies
The first aDNA studies used bacterial cloning to amplify small sequences retrieved from skins of animal and human mummies, and revealed the inefficient reaction kinetics of this technique (Higuchi et al., 1984; Pääbo 1985, 1989). These studies demonstrated that the genetic material surviving in ancient specimens was often principally microbial or fungal in origin. Endogenous DNA was generally l...
متن کاملEpigenetics of Ancient DNA
Initially, the study of DNA isolated from ancient specimens had been based on the analysis of the primary nucleotide sequence. This approach has allowed researchers to study the evolutionary changes that occur in different populations and determine the influence of the environment on genetic selection. However, the improvement of methodological approaches to genome-wide analysis has opened up n...
