Is the outcome of evolution predictable?
If one would rewind the tape of life, would evolution result in the same outcome? The Harvard evolutionary biologist Stephen Jay Gould came up with this famous thought experiment. He suggested that evolution would not repeat ...
First Swedish hard-rock diamonds discovered
An Uppsala-led research group has presented the first verified discovery of diamonds in Swedish bedrock. The diamonds are small, but provide important clues to the geological evolution of rocks.
Slow-growing galaxies offer window to early universe
What makes one rose bush blossom with flowers, while another remains barren? Astronomers ask a similar question of galaxies, wondering how some flourish with star formation and others barely bloom.
Primitive microbes stole bacterial genes on a surprising scale
A University of Otago researcher is part of an international team that has discovered that horizontal gene transfer (HGT) played a surprisingly large role in the evolution of primitive microbes known as archaea.
New clues behind the resilience of a leading sexually transmitted pathogen, Chlamydia
In the advanced online edition of Molecular Biology and Evolution, authors Domman, et al. have explored factors behind the resilience of the most common sexually transmitted disease in the U.S., chlamydia, with an estima ...
The cichlids' egg-spots: How evolution creates new characteristics
The evolution of new traits with novel functions has always posed a challenge to evolutionary biology. Studying the color markings of cichlid fish, Swiss scientists were now able to show what triggered these ...
Treasure trove of ancient genomes helps recalibrate the human evolutionary clock
Just like adjusting a watch, the key to accurately telling evolutionary time is based upon periodically calibrating against a gold standard.
