Next week prof. Marcelo R. Sánchez-Villagra (Palaeontological Institute and Museum, University of Zurich) will give a presentation titled: “Evolution in the Neotropics as North and South America connected: new discoveries of terrestrial and marine fossils and their ecological and biogeographic significance”. Here is an abstract:
“New palaeontological discoveries in northern South America characterize faunas of terrestrial mammals just before and during the closure of the Central American Seaway (CAS). The first records of migrants from North American mammals in this region (carnivorans and camelids) are associated with recent landscape changes in younger deposits that document major landscape changes. But fossils of two marine groups do speak for an earlier closure of the Central American Seaway than classically assumed. Data derived from a long term field efforts (Miocene to the Pleistocene) resulted in fossil sharks and rays from 67 geological units in 17 countries, from both shallow and deep-water habitats. The highest faunal similarity between the assemblages from the Eastern pacific and the Western Atlantic regions is at the early Miocene, with subsequent faunal differentiation within each of those regions, probably related with the increasing closure of the CAS and thus the formation of a barrier. Studying sea catfishes with novel calibration on genome-wide data, we identify a series of divergences between groups of Caribbean and Pacific fishes around 10 Ma, indicating vicariant speciation millions of years before the final isthmus closure. Terrestrial and marine fossils, integrated in ecological and biogeographic contexts, provide an understanding of major events of evolution in the tropics impossible to obtain based on molecular data alone.”
We were also thinking to go for drinks or dinner afterwards.

next week we will have Dr. Josephine Joordens from Leiden University visiting us. She will give us a talk in the club titled: “The Turkana basin: a mere marginal area in the grand theatre of African hominin evolution?”. Here is a short introduction to projects she works with:
“My premise is that hominins should be regarded as just another mammal surviving, reproducing and evolving in its environment. Therefore, it is crucial to gain detailed knowledge of hominin paleoenvironments, faunal context and ecology. An important underlying assumption in my research is that the presence of water always must have been an important factor for hominins: as drinking water, but also as a source of freshwater and marine food resources.
Presently my research consist of three ongoing projects:
TURKANA: This project focuses on reconstructing climate and environment in the Turkana Basin (Kenya) of ~2 million year ago, when two early Homo species together with Paranthropus boisei roamed the landscape. It is done in the framework of the ICDP Hominin Sites and Paleolakes Drilling Project (HSPDP), and the Turkana Cyclostratigraphy Project (see NWO and Feibel’s Lab). In 2013, a core was drilled in West Turkana paleolake deposits, and we did a complementary outcrop fieldwork near the drill site. The first articles are now in review and will be published in the course of 2017.
COASTAL ORIGINS? In 2013 I was awarded a NWO Veni Grant and started this project (see Leiden news) that aims to develop a biogeographical framework for early hominin evolution in Africa, between ~5 and 2.5 million years ago. I hypothesize that recurrent climatically stable episodes, paced by eccentricity, caused recurrent riverine connections between coastal refuge areas and inland marginal areas, including the Chad Basin in West-Central Africa. To assess occurrence and timing of such East-West dispersal corridors, we use genetic distance between extant fish populations in Lakes Turkana and Chad as proxy for past hydrographic connectivity between these basins.
TRINIL: My other research project centers on the rich fossil fauna from the Homo erectus type locality Trinil on Java (Indonesia). This unique collection, excavated by my scientific hero Eugène Dubois (1858-1940) and housed at Naturalis in Leiden, is a treasure trove that may hold many important clues to the behaviour and cognition of Javanese Homo erectus. Following our 2015 publication in Nature (on shell material from the Dubois Collection) we were invited by the National Research Center for Archaeology ARKENAS (Jakarta) to collaborate in a new field study of this classical site. In August 2016, together we successfully conducted a pilot fieldwork in Trinil that provides a key fundament for future studies.In May 2017 I have been awarded the prestigious Vidi grant from NWO to continue our research in Trinil for 5 years, starting in January 2018.“

next week we will have a presentation by Mikko Ijäs: “Fragments of the Hunt : Persistence Hunting, Tracking and Prehistoric Art”. Everyone is warmly welcome to participate!
Mikko Ijäs is a doctor of Arts student in the Aalto University in Helsinki. Ijäs graduated as a Masters of Arts in 2006 from the department of photography of the University of Arts and Design, Helsinki. Ijäs’s doctoral dissertation work in progress titled “Fragments of the Hunt” deals with the evolution of art in the context of ethnography, paleontology, art history and neuropsychology. Ijäs’s works are represented in various collections and he has been exhibiting widely both in Finland and abroad. (http://www.mikkoijas.com/Mikko_Ijas/Mikko_Ijas.html)
