Palaeoenvironmental evolution in SW Iberia during the Late Pleistocene and the Holocene

Considering southern Iberia as a key territory in terms of geoarchaeology and biodiversity, this project aims to enrich the knowledge on how palynological records mirror some abrupt events, discern the possible causes to some long term trends in vegetation, and understand the impact of palaeoenvironmental changes in human populations from the LGM to the Late Holocene.

It has been a long-standing and passionately discussed hypothesis that important developments in human origins over the last 6-8 Ma coincided with environmental change, including cooling, drying, and wider climate fluctuations. However, testing these hypotheses is difficult as both high resolution climate records and fossil records of early human populations are often incomplete and poorly dated. Thus, to better understand the role that past African climate changes might have played in the evolution and dispersal of our ancestors, in particular Homo sapiens, we have developed a ~620,000 year record of humidity variability from the Chew Bahir basin situated in southern Ethiopia.

CRC-Lecture July 13: Loess in central Iberia: The significance of Heinrich events, and implications for cultural turnover periods by Daniel Wolf

by Daniel Wolf,
Institut für Geographie, TU Dresden

On the Iberian Peninsula terrestrial archives that shed light on palaeoenvironmental conditions during the last glacial period are very rare. Due to the proximity of the North Atlantic a coupling between marine processes and terrestrial environments is suspected, but still difficult to verify.

Based on extensive stratigraphic work and abundant luminescence dating (OSL) on the upper Tagus loess record, multiple phases have been identified that point to brief and vigorous loess deposition related to gusty winds under generally dry conditions. By means of grain-size patterns, heavy mineral distributions, and δ13C values of n-alkane compounds we are able to draw a detailed picture of last glacial palaeoenvironmental and palaeohydrological conditions in the Iberian interior. Moreover, findings on human occupation patterns in central Iberia suggest that cultural turnover periods that were often tentatively correlated with Heinrich events in fact appear to be related to extreme environmental conditions.

In this talk we aim to discuss the importance of different level of experimentation to identify and interpret the different types of use-wear traces found on archaeological artifacts. While the whole experimental workflow (organization, design and mechanical apparatus) will be the focus of this talk, this will also be illustrated by a case study on the study of Ground tone tool from the Middle Paleolithic in the Levante. This ongoing study, will discuss preliminary results from mechanical experiments, designed to understand and quantify major aspects that influence use-wear formation on limestone percussive tools.

Workshop Feb 3rd & Mar 3rd: “How to write an academic publication in English”

By: Write English
Coach: Lesley-Anne Weiling

Date: Monday, 3. & 10. February 2020
Time: 9:30 – 17:00 h
Location: BFS 11 – Seminarraum 1.313, 1. OG

This two-day academic writing workshop is for researchers and graduate students who wish to publish research articles in English. The aim is to demystify the writing process, improve the style and structure of your English academic papers and make you a more confident writer.

Day one will focus on the building blocks of good writing, covering topics such as classic mistakes made in written academic English, the structure of an English paper, paragraphs and sentences, vocabulary and phrases and punctuation. On day two, we build on the knowledge and skills of the first day of the workshop.  Participants will have the opportunity to apply newly learned skills by working on their own texts as well as analysing good writing by authors in their field. In addition, on the second day, we focus on integrating a narrative style into your abstract and introduction, as well as indicating your paper’s importance. 

Preparation: Participants should bring along at least two sample papers from their field of research, ideally written by native speakers of English. In addition, participants should bring along a writing project they wish to work on during the workshop.

14th Martin-Schwarzbach-Colloquium

Dear Martin-Schwarzbach attendee,
Thanks for your interest in the 14th annual Martin-Schwarzbach colloquium. With deep regret we have to announce, that this year’s Martin-Schwarzbach colloquium is cancelled due to the current Corona crises. The decision has not been made easily, but we here follow regulations provided by the government and the University of Cologne (https://portal.uni-koeln.de/coronavirus). We surely will continue with our colloquium series next year (new date: 30. April 2021) and are currently trying to invite this year’s speakers again for next year. Please accept our sincere apologies for these unexpected circumstances. We would be very pleased to welcome you next year at our colloquium.

We wish you all the best in these difficult times. Stay healthy!
With kind regards,
Hannah Hartung & Frank Schäbitz

Marco Peresani: Neanderthal and sapiens in Italy 50-40 ky BP. A discussion on the ecological and cultural dynamics with a reference to the northern Adriatic rim

by Marco Peresani,
Università di Ferrara, Dipartimento di Studi Umanistici, Sezione di Scienze Preistoriche e Antropologiche, Ferrara, Italy

One of the most investigated topics in palaeoanthropology is the pivotal phase in human evolution represented by the Middle to Upper Palaeolithic in Western Eurasia. When and how early Homo sapiens replaced the native population, Homo neanderthalensis, and the relations between these biological taxa and their respective material cultures are subjects of heated debate. Pieces of this intriguing puzzle have been unveiled in recent years from the cultural complexes known as the final Mousterian, the Uluzzian and the Protoaurignacian, which spread across the central Mediterranean rim from the Italian peninsula to the south of the Balkans (Palma di Cesnola 1989; Moroni et al. 2013). At present, the Uluzzian is the oldest known cultural expression associated with Anatomically Modern Humans (Benazzi et al. 2011) and is currently best known by its stratigraphic position above the final Mousterian in cave sedimentary sequences. This has also been observed in northern Italian caves, which expanded its cultural borders from what was thought to be exclusively southern after the discovery of assemblages at Grotta Fumane (Peresani et al. 2016) and at Riparo Broion (Peresani et al., 2019). This geographical space constrained from the Apennine, the Southern Alps, the Dinarids and the shallow Adriatic reach of MIS3, features high ecological diversity, and is of pivotal importance for influencing the possible human migratory routes and interactions between these biocultural worlds. To contribute to disentangle the story of the first modern human arrivals and the last Neanderthals in this area, we display on a behavioural perspective the possible relations occurred among different human groups by resuming a set of recently achieved evidence on chronology, human ecology and cultural aspects in the effort to evaluate the implications of innovations recorded in the 50-40 ky BP time frame.

Bahru Zinaye Asegahegn: Late Quaternary environmental change on the Southeastern Ethiopian Highlands inferred from the recently dried up Lake Haramaya

by Bahru Zinaye Asegahegn,
University of Cologne

Lacustrine sediments are considered to be the most common, usually long and reliable continental climate archives. This project focuses on the reconstruction of environmental conditions, by using lake sediment cores and geochemical proxies, since the time frame of first appearance of Anatomically Modern Humans (AMH) in Ethiopia and their dispersal across and out of Africa to elucidate the reason behind the movement with regard to the different “out of Africa” hypotheses. Furthermore, understanding the past environment and the human response to the changing climate and environmental conditions is vital for devising a mechanism to adapt to the new environment. Here, we will present the study site, its current geo-environmental setting, the methodologies we use and the preliminary results.

Katharina Neumann & Barbara Eichhorn: Phytoliths as proxy for African palaeoenvironment and human evolution – chances and limits

by Katharina Neumann & Barbara Eichhorn,
University Frankfurt

Phytoliths are solid silica bodies formed in various plant tissues and organs, e.g. in leaves, stems, fruits and seeds. Due to their very durable nature, they are often present in ancient sediments and soils where other plant remains have not been preserved. Therefore they can play an important role for reconstructions of palaeoenvironments and human plant use in the past. Grasses (Poaceae) produce a myriad of different phytolith morphotypes and are therefore well-suited for palaeoenvironmental reconstructions, especially in Africa where savannas and grasslands constitute the majority of vegetation types. Woody plants and herbs, on the other hand, often have only very few or unspecific phytoliths and are therefore mostly under-represented in phytolith assemblages. We will discuss potential and limitations of phytolith research in West, Central and East Africa, based on recent case studies.
