Unique Coastal Defence Research
'We will be comparing the 3D beach evolution and sediment transport in the CRF model with measurements made on the Sussex coast at Elmer, on which the model is based,' explains Dr Chadwick, Reader in Coastal Engineering.

Europeans' understanding of science, evolution, more advanced than Americans
When it comes to scientific literacy, Americans aren't nearly as evolved as they may think. In fact, only about 40 percent of American adults accept the basic idea of evolution, a figure much lower than any European country. view more (2007-02-16)

Selection of the fittest
A new study shows that schools and many education programmes are failing to provide students with a basic understanding of evolution. It is famously difficult to explain evolutionary principles without resorting to anthropomorphic or figurative language. Evolution 'selects' the fittest individuals; species 'adapt' to change. Both of these phrases... view more... (2002-03-18)

Human brains pay a price for being big
Metabolic changes responsible for the evolution of our unique cognitive abilities indicate that the brain may have been pushed to the limit of its capabilities. Research published today in BioMed Central's open access journal Genome Biology adds weight to the theory that schizophrenia is a costly by-product of human brain evolution. view more (2008-08-05)

Evolution: fish select for the survival of teh fittest
An important breakthrough has been made in determining the forces responsible for the evolution of populations in nature. By studying wild populations of grayling (a close relative of salmon), Mikko Koskinen and Craig Primmer at the University of Helsinki and Thrond Haugen at the University of Oslo found that natural selection, a force suggested... view more...

Ambient light influences the evolution of colour signals
In light-contrasted ecosystems, ambient light and background colours influence the evolution of animal coloration. Because maximal conspicuousness is achieved for signals which are rich in the colours of ambient light but poorly reflected by background, different signals will be cryptic or conspicuous at different heights in tropical rainforest.... view more...

Columbine flowers develop long nectar spurs in response to pollinators

Conflict over rearing young shapes breeding systems
An article in the October 2006 issue of BioScience, the monthly journal of the American Institute of Biological Sciences (AIBS), describes evidence that conflict between male and female shorebirds over which member of a breeding pair will raise their young has had a profound influence on the evolution of breeding systems in these birds. view more (2006-10-03)
