چکیده

The advent of the polyrnerase chain reaction (PCR) is transforming many aspects of molecular biology. An example of this is the field of ‘molecular archaeology’ the retrieval of DNA sequences from ancient tissues which owes its very existence to this technique [ 11. The ability of the PCR to amplify a few intact DNA molecules that are extracted from old tissues has for the first time ‘made it possible to go back in time and study old DNA sequences. Indeed, the PCR can even recreate longer sequences from short fragments in the test tube [2]. Thus, we can now dream :about catching molecular evolution red-handed. So far, dlreams about this sort of time travel have come true only for short trips into the past. Until recently, the oldest DNA sequences determined were 40000-year-old mammoth sequences (RG. Higuchi, unpublished results).

This commentary on Potts et al provides a critical view on their thesis that increasing the level of education among women is likely to reduce terrorism. Presence of a strong family planning program enables women to control family size resulting in women’s public participation more likely and facilitating the emergence of small birth cohorts who are less likely to become unemployed. In spite of...

Molecular phylogenetics and historical biogeography among salamandrids of the "true" salamander clade: rapid branching of numerous highly divergent lineages in Mertensiella luschani associated with the rise of Anatolia.

Phylogenetic relationships among salamandrids of the "true" salamander clade are investigated using 2019 aligned base positions (713 parsimony informative) of 20 mitochondrial DNA sequences from the genes encoding ND1 (subunit one of NADH dehydrogenase), tRNA(Ile), tRNA(Gln), tRNA(Met), ND2, tRNA(Trp), tRNA(Ala), tRNA(Asn), tRNA(Cys), tRNA(Tyr), and COI (subunit I of cytochrome c oxidase), plus...

Depositional Environment and Sequence Stratigraphy of the Oligocene-Miocene Deposits North and East of Dehdasht, Izeh Zone, Zagros Basin, Iran

In this study, four well-exposed outcrops of the Asmari Fm in the southeastern part of the Izeh Zone of the Zagros Mountains were measured and sampled. In this region, the Asmari Fm is Oligocene to Early Miocene in age as determined by large benthic foraminifera. Based on depositional geometries, biogenic contents and lateral and vertical variations of facies, three depositional models are prop...

Paleoenvironmental Reconstruction of Miocene Surma Succession in the Well Rashidpur # 04 of Bengal Basin Using Log Facies Interpretation

Detailed log facies studies of Miocene succession in the well Rashidpur-04, Rashidpur structure, Surma Basin were carried out by integrating wireline log and limited core sample data in order to reconstruct the paleoenvironments of deposition. Based on the analysis of the log motifs, grain size, sand/shale ratio and major change in gamma ray log motifs, two major depositional sequences were ide...
