scientists uncover the source of an almost two billion year delay in animal evolution
Simon Poulton
27.3.08
A deficiency of oxygen and the heavy metal molybdenum in the ancient deep ocean may have delayed the evolution of animal life on Earth for nearly two billion years.
Dr Simon Poulton, Civil Engineering and Geosciences, Newcastle University, was part of an international team of biogeochemists who took part in the University of California-led study.
The study’s results are published in today’s edition of Nature.
‘For decades it was assumed that the ocean became oxygenated shortly after an initial rise in atmospheric oxygen about 2.4 billion years ago,’ said Dr Poulton. ‘This study provides independent confirmation that there was a major delay in the oxygenation of the ocean, and furthermore, it now appears that the availability of molybdenum may have played a crucial role in animal evolution. At last, a coherent picture of the environmental conditions that led to the evolution of animal life is emerging.’
The researchers arrived at their conclusion after tracking molybdenum in black shales, a kind of sedimentary rock rich in organic matter found in the ocean. Molybdenum is a key micronutrient for the life-forms that control the production of oceanic and atmospheric oxygen.
Following the initial rise of oxygen in the Earth’s atmosphere 2.4 billion years ago, oxygen was transferred to the surface ocean to support oxygen-demanding micro-organisms. However, the diversity of these single-celled life forms remained low, and their multi-cellular ancestors (animals) did not appear until about 600 million years ago.
Suspecting that deficiencies in oxygen and molybdenum might explain this evolutionary lag, the team measured the abundance of molybdenum in ancient marine sediments over time to estimate how much of the metal had been dissolved in the seawater in which the sediments formed.
The researchers found significant, firsthand evidence for a molybdenum-depleted ocean compared to the high levels measured in today’s oxygen-rich seawater.
‘These molybdenum depletions may have retarded the development of complex life such as animals for almost two billion years of Earth’s history,’ said project leader Professor Timothy Lyons, at the University of California’s Department of Earth Sciences. ‘The amount of molybdenum in the ocean probably played a major role in the development of early life. As in the case of iron today, molybdenum can be thought of as a life-affirming micro-nutrient that regulates the biological cycling of nitrogen in the ocean. At the same time, molybdenum’s low abundance in the early ocean highlights the global extent of oxygen-poor seawater and implies that the amount of oxygen in the atmosphere was still low.’
‘Knowing the amount of oxygen in the early ocean is important for many reasons, including a refined understanding of how and when appreciable oxygen first began to accumulate in the atmosphere. These steps in oxygenation are what ultimately gave rise to the first animals almost 600 million years ago – just the last tenth or so of Earth’s history.’
For animal life to commence, survive and eventually expand on Earth, a threshold amount of oxygen – estimated to be on the order of 1 to 10 percent of present atmospheric levels of oxygen – was needed.
Past research has shown that Earth’s oxygenation occurred in two major steps: The first step, around 2.4 billion years ago, took place as the ocean transformed to a state where only the surface ocean was oxygenated by photosynthesizing bacteria, while the deep ocean was relatively oxygen-free.
The second step, around 600 million years ago, marked the point when the entire ocean became fully oxygenated through a process not yet fully understood. The purpose of this research was to find out the state of the ocean between the two steps.
By tracking molybdenum in shales rich in organic matter, researchers found the deep ocean remained oxygen and molybdenum-deficient after the first step. This condition may have had a negative impact on the evolution of early eukaryotes, our single-celled ancestors. The molybdenum record also shows that the deep ocean only became fully oxygenated by around 550 million years ago.
According to this research, the timing of the oxygenation steps suggests that significant events in Earth’s history are related. Scientists have long speculated that the evolution of the first animals was somehow linked to the so-called Snowball Earth hypothesis, where the Earth was covered from pole to pole in a thick sheet of ice for millions of years. Oxygenation of the oceans and the evolution of animal life occurred shortly after the last of Earth’s global glaciations.

19.3.08
The final year geomatics students have returned from the inaugural three-day study tour looking at Aspects of Applied Geomatics. The trip comprised two site visits, one exhibition and a company visit.
On Wednesday 12 March, the students visited the 2012 Olympics site in East London. In addition to a bus trip around the site to see the enabling works, the group received a talk from Ordnance Survey (www.ordnancesurvey.co.uk) and CML about the "Olympic Grid" coordinate system and the use of GIS on the site respectively.
Thursday 13 March saw the students head to Docklands for the Oceanology International exhibition. Students were tasked with visiting several companies and vessels to explore the use of geomatics in the marine environment. From there, the group headed to Maltby Surveys in Sussex where river, internal building and laser scan surveys were all discussed. The day finished with a visit to Herstmonceux and the NERC Space Geodesy Facility.
Friday 14 March was taken up with a visit to Ordnance Survey for a combination of talks and tours covering OS Net, cartography, print services and photogrammetry. |

engineers rugby team runners-up in Birmingham tournament
James Barber and Jack Payne
11.3.08
Newcastle University Engineers Rugby Club recently travelled to Birmingham to compete in a tournament arranged by Birmingham University Engineers Rugby Club. The competition was in aid of the Matt Hampson Trust and was attended by several teams from the midlands area, making the Newcastle Engineers the most exotic and far away team involved.
The tournament took place on Saturday 8th March with Newcastle Engineers playing Birmingham Engineers in the showpiece opening match. Newcastle won the game and hence the Engineers' bragging rights, and then went on to become the unbeaten winners of their group. Newcastle Engineers then went on to reach the final of the competition, narrowly losing to Birmingham University Freshers 1st XV.
The team were proud to represent the University and in particular the School of Civil Engineering and Geosciences, who kindly paid for the team's travelling expenses.
The trip was the first time the engineers have played outside Newcastle and proved a huge success. Hopefully with the continuing support of the school and participation of Engineering students, similar trips will be possible in the future.
We're always looking for new players and anyone interested in playing for the Engineers RFC (not exclusive to Engineers) can contact us on j.e.barber@ncl.ac.uk or j.w.payne@ncl.ac.uk

gifted and talented school students spend day at CeG
Tom Bramald
11.3.08
On Saturday 8 March 40 school students from across the North East completed a Gifted and Talented Masterclass with the School of Civil Engineering and Geosciences.
Half the students completed a geomatics project that included fieldwork with engineering and satellite surveying equipment. Their data were then processed to generate a Digital Terrain Model that was rendered in the popular software package, Google Earth.
The other group of students looked at climate change. They spent time in CEGs hydraulic laboratory looking at rainfall, runoff and flood defence and then prepared presentations about some of the hazards a changing climate might present to society.
Feedback from both sessions is very positive indeed.

climate’s future hangs in the balance
Jim Hall
17.1.08
The Earth’s climate could reach its ‘tipping point’ within just a few hundred years, according to new research published this week.
Results published in the Proceedings of the National Academy of Sciences journal show that human-induced climate change may affect us more quickly than we imagined.
Professor Jim Hall, Earth Systems Engineering, was among the scientists warning that a number of systems influencing the Earth’s weather patterns could suddenly collapse due to even a slight increase in global temperatures.
Among the top ‘tipping elements’ identified is the collapse of the Atlantic thermohaline circulation (about 100 years); dieback of the Amazon rainforest (about 50 years); and the decay of the Greenland ice sheet (about 300 years). Another crucial ecological system indicator is the end of the Indian summer monsoon, which could be as little as a year away.
Professor Hall, who is based in the Tyndall Centre for Climate Change Research in the University’s School of Civil Engineering and Geosciences, worked alongside academics from the Potsdam Institute for Climate Impact Research in Germany. Their part in the international study involved conducting in-depth investigations with 52 experts in the field to ascertain which tipping elements they believed would have the most effect on the climate and how likely they thought this would happen.
“There’s still some diversity of opinion among experts, but following this study we are able to show which elements are universally considered to be most sensitive to climate change,’ said Professor Hall.
The study, which was led by the University of East Anglia, suggests that, in principle, early warning systems of significant climatic change could be set up using real-time monitoring and modelling.

watershed management consultancy in Africa
Geoff Parkin
17.1.08
Geoff Parkin was invited by Concern Worldwide (international development charity working with highly impoverished communities) to visit Rwanda in Dec 2007 to advise on the development of community based watershed management approaches as part of their Livelihood Security Capacity Building Project in the Gakenke District. Rwanda has suffered from intensive agricultural development particularly since the 1994 genocide, leading to severe problems with erosion and water access, and has some of the world’s poorest rural communities. During the reconnaissance visit a potential pilot watershed was identified, and contacts were established at all levels including peasant farmer’s associations, academics, local Rwandan and UK government DfID representatives, and a national climate change project, helping to support Concern’s activities and as a basis for developing possible future funding opportunities.
A faculty seminar “Is sustainable development relevant in cases of extreme poverty? Perspectives from Haiti and Rwanda” will be given by Geoff Parkin on 29 January 2008 at 1:10pm, Research Beehive Room 2.20

evidence of glaciation in 'super greenhouse' world
Thomas Wagner
11.1.08
Science paper
Large ice-sheets existed on Earth about 91 million years ago, during one of the warmest periods since life began, an international team of scientists reports this week.
The findings, published in the journal 'Science' on January 11, challenges the popular assumption that large glaciers could not have existed in the 'super greenhouse' climate of the Cretaceous period, when tropical surface ocean temperatures reached as high as 35-37C (95-98.6F).
Scientists from the USA, UK, Germany and Netherlands found evidence of an approximate 200,000 year period of widespread glaciation during the Turonian "super-greenhouse" period of the Cretaceous, with ice sheets about 60 per cent the size of the modern Antarctic ice cap.
The team obtained their evidence from detailed geochemical and isotopic analyses of organic carbon-rich sediments that were deposited in the western Equatorial Atlantic at Demerara Rise off Surinam at that time. The sediments were recovered during the Ocean Drilling Program Leg 207 and contained glassy carbonate shells of tiny sea creatures, foraminifera, that lived in the Cretaceous seas. These shells'captured' chemicals that were present at the time, providing clues about the temperature, composition and salinity of the seawater.
The fossil shells consist of pristine carbonate, which contain oxygen and other elements. By analysing the different types of oxygen atoms (isotopes) in these shells scientists at the Scripps Institution of Oceanography in the USA were able to reconstruct sea temperature, both at the surface and at depth.
Meanwhile, a European team at the Universities of Newcastle and Cologne in the UK and Germany, and the Royal Netherlands Institute for Sea Research (NIOZ) in the Netherlands studied the composition of organic molecules of membrane lipids from archea in exactly the same sediments, providing an independent temperature record of surface waters for the Cretaceous western tropical Atlantic.
Because the growth of continental ice enriches seawater in the isotope 18O, the d18O chemistry, when constrained by biomarker temperature estimates, was used to estimate the size of continental ice sheets. By combining these two lines of data, the team was able to show that differences in the records of the tropical oceans were consistent with periods of glacial formation.
Professor Thomas Wagner, of the School of Civil Engineering and Geosciences and the Institute for Research on Environment and Sustainability at Newcastle University, said: 'Speculation about whether large ice caps could have formed during short periods of the Earth's warmest interval has a long history in Geology and climate research, but there has never been final conclusive evidence. This uncertainty remained as there is very little direct evidence from high latitude rocks supporting or disproving the concept; also computer simulations have difficulties to accurately model climate conditions at polar latitudes during past greenhouse conditions'.
'Our research from tropical marine sediments provides strong evidence that large ice sheets indeed did exist for short periods of the Cretaceous, despite the fact that the world was a much hotter place than it is today, or is likely to be in the near future', Professor Jaap S. Damste from the Royal NIOZ adds.
The results are consistent with independent evidence from Russia and the USA that sea level fell by about 25-40 metres at this time. Sea level is known to fall as water is removed from the oceans to build continental ice-sheets and to rise as ice melts and returns to the sea. Today, the Antarctic ice cap stores enough water to raise sea level by about 60 metres if the whole mass melted and flowed back into the ocean.
Dr Andre Bornmann, who led the research at Scripps Institute of Oceanography, University of California, together with Professor Richard Norris, and who has since moved to Leipzig University in Germany, said it was not clear where such a large mass of ice could have existed in the Cretaceous period or how ice growth could have started.
'This study demonstrates that even the super-warm climates of the Cretaceous Thermal Maximum were not warm enough to always prevent ice growth. Certainly, ice sheets were much less common during the Cretaceous Thermal Maximum than they are during more recent "Icehouse" climates, allowing tropical plants and animals like breadfruit trees and alligators to frequent the high arctic. However, paradoxically past greenhouse climates may actually have aided ice growth by increasing the amount of moisture in the atmosphere and creating more winter snowfall at high elevations and high latitudes,' he said.
The findings of this study provide compelling support for another related study published by Fletcher and co-authors from The University of Sheffield and Yale in the January 2008 issue of the journal, Nature Geoscience. In their study Fletcher and co-authors reconstructed atmospheric carbon dioxide concentrations for the Mesozoic and early Cenozoic below the simulated threshold for the initiation of widespread glaciation on several occasions and speculated on the repetitive occurrence of cold intervals in a general greenhouse world.
