Evolution Follows A Predictable Genetic Pattern Researchers Find
2012-10-26 10:20:03

Evolution, often perceived as a series of random changes, might in fact be driven by a simple and repeated genetic solution to an environmental pressure that a broad range of species happen to share, according to new research. Princeton University research published in the journal Science suggests that knowledge of a species' genes – and how certain external conditions affect the proteins encoded by those genes – could be used to determine a predictable evolutionary pattern...

Genetic material derisively called "junk" DNA because it does not contain the instructions for protein-coding genes and appears to have little or no function is actually critically important to an organism's evolutionary survival, according to a study conducted by a biologist at UCSD. In the October 20 issue of Nature, Peter Andolfatto, an assistant professor of biology at UCSD, shows that these non-coding regions play an important role in maintaining an organism's genetic integrity. In his...
