Problems of reproducibility – does geologically ancient DNA survive in amber–preserved insects?
Attempts to reproduce DNA sequences from amber– and copal–preserved bees and flies have failed to detect any authentic ancient insect DNA, suggesting that DNA does not survive over millions of years even in amber, the most promising of fossil environments. Expand
Ancient DNA Research in Maritime and Underwater Archaeology: Pitfalls, Promise, and Future Directions
The rapid progression of DNA technology allows for the application of recently developed techniques to an ever-growing body of archaeological and environmental material recovered from submergedExpand
DNA from resin-embedded organisms: Past, present and future
It is demonstrated here, for the first time, that although a labile molecule, DNA is still present in platypodine beetles embedded in six- year-old and two-year-old resin pieces from Hymenaea verrucosa collected in Madagascar, concluding that it is therefore possible to study genomics from resin-embedded organisms, although the time limits remain to be determined.

The age of museomics : How to get genomic information from museum specimens of Lepidoptera
A targeted enrichment approach to sequence nuclear loci from museum specimens dating back to 1892 for 35 taxa across the order Lepidoptera is used, and the usefulness of various museomics applications are shown, including the use of TE and WGS for phylogenomic studies. Expand
Ancient DNA Analysis of the Thulamela Remains: Deciphering the Migratory Patterns of a Southern African Population
The author states that the aim of this book is to provide a systematic guide to the usage of Abstrak, and to clarify the meanings of terms such as “strak” and “stationary”. Expand

The history of land vegetation


Origins and relationships of tropical North America in the context of the boreotropics hypothesis.
These findings are consistent with the boreotropics hypothesis, and additional evidence suggests that many tropical elements in North America could be descendants of northern tropical progenitors. Expand
Hymenaea protera sp.n. (Leguminosae, Caesalpinioideae) from Dominican amber has African affinities
It is proposed that at least the majority, if not all, of the amber recovered from La Toca mine and other mines in the vicinity with similar-aged deposits originated from H. protera and is interpreted as supporting a hypothesis that the genusHymenaea arose in the late Cretaceous on the combined South American-African continents.

Chloroplast DNA sequence from a Miocene Magnolia species
The extraction of DNA from fossil leaf samples from the Miocene Clarkia deposit, the amplification of an 820-base pair DNA fragment from the chloroplast gene rbcL from a fossil of the genus Magnolia, and its subsequent sequencing extend the ability to analyse ancient DNA and may open new avenues into problems in palaeobotany, biogeography, and in the calibration of mutation rates.

The neighbor-joining method: a new method for reconstructing phylogenetic trees.
The neighbor-joining method and Sattath and Tversky's method are shown to be generally better than the other methods for reconstructing phylogenetic trees from evolutionary distance data. Expand
