For this Honours Class there will be additional costs (€ 450) for the excursion.
This course is an Honours Class and therefore in principle only available to students of the Honours College, and the BSc curriculum of LUC The Hague. There are a few places available for regular students.
Life in all its diversity evolved in the marine environment. In this course taught at Leiden University and at the Marine center of the University Pierre et Marie Curie, France, in Roscoff we teach aspects of the Tree of Life, we focus on the transition from mono-cellular life to animal life conquering the continents in the early Paleozoic, and we address Earth history from the time of the origin of life to the environments that made the emergence of land life possible.
We bring together a multi-disciplinary team of marine biologists, ecologists, physicists and geophysicists, isotope geochemists, astronomers, mathematicians, paleontologists and geologists to teach a course in geo-biology with special interest in the Tree of Life, the origin of life, and the environments in which life evolved.
After completion of the course the students will be able to:
Identify key fossils from the Paleozoic era;
Identify marine organisms as can be found along the coast of Normandy near Luc-sur-Mer;
Recognize geological structures in the field;
Read a geological map;
Identify a range of sedimentary and magmatic rocks.
After completion of the course the students will know:
The evolution of continents since the early Archean era;
The radiation of life in the Eocambrian and early Phanerozoic;
Adaptation of life to living on land in the Paleozoic era;
The major Bauplans of marine organisms;
The basic structure of the Tree of Life.
have an understanding of the relation of land forms and underlying geological structures;
have an understanding of different taxa of the Tree of life, both in the paleontological record and in the modern marine environment;
develop a holistic view of earth processes occurring at the earth surface through time from geophysical and geochemical view points on the origin and evolution of life.
6 June – 9 June and 12 June – 15 June, 17.00 – 20.00 hrs, and 2 weeks excursion from 19 Augustus until 3 September 2017.
Note: For this Honours Class there will be additional costs (€ 450) for the excursion.
6 June – 15 June: Gorlaeus Lab, Einsteinweg 55, Leiden, Room 06.
July or August: Brittany and Normandy, France (there will be additional costs (€ 450) for the excursion.)
Theme 1: Geology: setting the stage for life
Lecture 1: From planetary accretion to continents. Earth history in the early stages of the earth.
Lecture 2. Timescales in Geology. From isotopic dating techniques to division of Earth history into different periods.
Lecture 3. The origin and significance of the earth’s magnetic shield.
Lecture 4. The composition of the early atmosphere, the oceans, and the sea floor, how this composition changed with time, and its relevance for the origin of life on earth.
Theme 2: Young Earth, young life- Lecture 5. Stable isotope systems as tracers of life: - Si and Fe isotopes as indicators of metabolism in the Archean. - 13C/12C fractionation through time, biological and inorganic causes.
Lecture 6. Exo Life.
Lecture 7. Origin of Life: The history of theories on the origin of life or biogenesis. Comparison of chemical and physical approaches to biogenetic theories. Biogenesis will be placed within the ecological framework of a development of reducing -> oxidising conditions.
Lecture 8. The thermodynamics of photosynthesis and its role in the development of the biosphere and its import on the atmosphere.
Theme 3: Crises and opportunities
Lecture 9. Life, but not as we know it. The first fossils of multicellular organisms, known as the Ediacara fauna, represent life forms very different of anything living today. After the Cambrian explosion, fossils show more familiar Bauplans. However, deposits like the Burgess shale revealed that in that period too, organisms thrived in the oceans unlike anything living today.
Lecture 10. Crises and opportunities. During the Palaeozoic, two mass extinctions occurred. The third major extinction wave, the largest ever recorded, signified the end of the era. About the possible causes of the various mass extinctions, the devastation they caused, and the opportunities provided during the aftermath.
Theme 4: Tree of life
Lecture 11. Genealogy of living organisms. From single cell to higher organisms.
Lecture 12. Stromatolites, a singular visual portal into deep time on earth, the emergence of life, and the evolving of the beautiful forms of life of modern time
Lecture 13. Modelling gene-regulation and cell-movement in early development of the sea anemone Nematostella vectensis and the scleractinian coral Acropora mellipora.
Theme 5: Evolution towards land
Lecture 14. A Tree of Plants: From a blue to a green planet
Lecture 15: on the emergence of insects from crustaceans
Lecture 16. Evolution of Chordata: there is something fishy about us.
Lecture 17. To boldly go where no vertebrate has gone before. During the Devonian the vertebrates started exploring and exploiting the land. A massive change, leading to a number of adaptation to deal with the hostile environment outside the water.
