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

12th Martin-Schwarzbach-Colloquium

The Centre for Quaternary Science and Geoarchaeology (QSGA) is pleased to announce its twelfth annual colloquium in honour of Martin Schwarzbach.
This year, our meeting focuses on human dispersal and paleoclimate at the crossroad on the Levant.
We are especially pleased that Thomas Litt (University of Bonn) and Michael Petraglia (Max Planck Institute for the Science of Human History) have accepted our invitation to Cologne.

We would like to extend a very cordial invitation to this exciting meeting!

Potts“The Environmental Dynamics of Human Evolution” 

East Africa is the source of much information about the evolution of early human ancestors. A synthesis of East African environmental data suggests that significant events in human origins typically developed during lengthy eras of strong climate fluctuation. Analysis of Earth’s orbital dynamics offers a model of alternating high and low climate variability over the past 5 million years.

This high/low variability model shows that fluctuations between arid and moist climate were important in the evolution of key human adaptations. The origin of the major early human lineages, critical transitions in stone technology, and the main geographic milestones in human origins all appear to coincide with prolonged intervals of intense climate variability. Climate dynamics and resource uncertainty likely shaped the adaptive versatility of our species, expressed by the expansion of mobile technologies, symbolic behavior, social networks, and behavioral diversity. Long climate sequences obtained by drilling in the East African Rift Valley, including near the site of Olorgesailie, Kenya, will test these ideas about the significance of adaptability in the origin of our species.

16.30 – 16.45h: Coffee Break

16.45 – 17.45h:        Mark Maslin

Mark Maslin“The Cradle of Humanity: How the changing landscape of Africa made us smart”

Current evidence suggests that all of the major events in hominin evolution have occurred in East Africa. Over the last two decades, there has been intensive work undertaken to understand African palaeoclimate and tectonics in order to put together a coherent picture of how the environment of East Africa has varied in the past. The landscape of East Africa has altered dramatically over the last 10 million years. It has changed from a relatively flat, homogenous region covered with mixed tropical forest, to a varied and heterogeneous environment, with mountains over 4 km high and vegetation ranging from desert to cloud forest.

The progressive rifting of East Africa has also generated numerous lake basins, which are highly sensitive to changes in the local precipitation-evaporation regime. There is now evidence that the rapid oscillation between the presence and absence of deep-water lakes in East Africa were concurrent with major events in hominin evolution. It seems the unusual geology and climate of East Africa created periods of highly variable local climate, which, it has been suggested could have driven hominin speciation, brain expansion and dispersal out of Africa. One example is the significant hominin speciation and brain expansion event at ~1.8 million years ago that seems to have been coeval with the occurrence of highly variable, extensive, deep-water lakes. This complex, climatically very variable setting inspired the pulsed climate variability hypothesis that suggests the long-term drying trend in East Africa was punctuated by episodes of short, alternating periods of extreme humidity and aridity. The fundamental question, however, remains how much did variations in the landscape versus social factors influence the 80% expansion of brain capacity and the dispersal out of Africa at 1.8 million years ago.
