AbstractIn 2019, the Rostock University Library acquired the report by Amerigo Vespucci (1454–1512) on transatlantic discoveries, which was published in 1505 by the city secretary Hermann Barckhusen (c 1460–1528/29) in Rostock under the title “Epistola Albericij. De novo mundo” [1505] and, unlike other editions, was published with a map. The special feature of the map is that it is the oldest map with a globular projection. Vespucci reported in a letter dated July 18, 1500 to Lorenzo di Pierfrancesco de' Medici about his voyage 1499–1500, which is an important source for the fact that his longitude determinations contributed to the realization that the transatlantic discoveries were about a continent. The letter also contains evidence that Vespucci was the originator of the globular projection. This marked the beginning of a departure from ancient traditions regarding the projections for world maps. To enable the combined representation of the “old world” together with the “new world” in one map, Vespucci's projection was later modified into an oval map, which was used, for example, by Franzesco Rosselli, Sebastian Münster and Abraham Ortelius.

Abstract Transpositions of Alu sequences, representing the most abundant primate short interspersed elements (SINE), were evaluated as molecular cladistic markers to analyze the phylogenetic affiliations among the primate infraorders. Altogether 118 human loci, containing intronic Alu elements, were PCR analyzed for the presence of Alu sequences at orthologous sites in each of two strepsirhine, New World and Old World monkey species, Tarsius bancanus, and a nonprimate outgroup. Fourteen size-polymorphic amplification patterns exhibited longer fragments for the anthropoids (New World and Old World monkeys) and T. bancanus whereas shorter fragments were detected for the strepsirhines and the outgroup. From these, subsequent sequence analyses revealed three Alu transpositions, which can be regarded as shared derived molecular characters linking tarsiers and anthropoid primates. Concerning the other loci, scenarios are represented in which different SINE transpositions occurred independently in the same intron on the lineages leading both to the common ancestor of anthropoids and to T. bancanus, albeit at different nucleotide positions. Our results demonstrate the efficiency and possible pitfalls of SINE transpositions used as molecular cladistic markers in tracing back a divergence point in primate evolution over 40 million years old. The three Alu insertions characterized underpin the monophyly of haplorhine primates (Anthropoidea and Tarsioidea) from a novel perspective.

AbstractArchaeological developments in the zone extending from Mesoamerica to the Andes are summarized in terms of the following topics: early man, the origins of agriculture, the interrelationships of the Nuclear American cultures, the ethnic identification of archaeological complexes, horizonal and tradition formulations, the place of Nuclear America in the hemisphere, relationships between the New World and the Old World, the rise of native American civilizations, and main trends since 1935. These trends include increasing chronological control, greater awareness of context, growing interest in culture process, and more clarity and precision in definitions.
