Scientists discover how fish evolved to float at different sea depths

Scientists at the University of Liverpool have discovered how fish have evolved over the last 400 million years to stay motionless at different water depths. A research team led by Dr Michael Berenbrink, a Comparative Physiologist at the School of Biological Sciences, has revealed how modern fish, such as pike and cod, have developed a way of floating at certain water levels using a gas-f...

Immune system has evolved to prevent autoimmune disease

Study suggests chronic infections may create autoimmune response New research finds the human immune system has foregone evolutionary changes that would allow it to produce better antibodies in less time because the improved antibodies would be far more likely to attack the body's own tissues. The Rice University study finds the immune system has evolved a near-perfect balance for produci...

Fitting in: Newly evolved genes adopt a variety of strategies to remain in the gene pool

The largest-ever experimental analysis of duplicated genes provides insight into mechanisms of evolution When Mother Nature creates an identical copy of a gene in an organism's genome, the duplicated copy is usually deleted, inactivated, or otherwise rendered nonfunctional in order to prevent genetic redundancy and to preserve biological homeostasis. In some cases, however, gene duplicat...

Sociality of sweat bees evolved simultaneously during climate change

In the first study to link social evolution to climate change, Cornell University entomologists show that the social behavior of many species of sweat bees evolved simultaneously during a period of global warming. This social evolution occurred much more recently than scientists ever thought -- only 20 million to 22 million years ago, compared with the social evolution of other insects, w...

World's largest flower evolved from family of much tinier blooms

The plant with the world's largest flower -- typically a full meter across, with a bud the size of a basketball -- evolved from a family of plants whose blossoms are nearly all tiny, botanists write this week in the journal Science. Their genetic analysis of rafflesia reveals that it is closely related to a family that includes poinsettias, the trees that produce natural rubber, castor oil plants...
