Latest Adaptation Stories

As the climate continues to change, it's unclear to what extent different species will be able to keep pace with altered temperatures and shifted seasons. Living organisms are the survivors of previous environmental changes and might therefore be expected to adapt, but are there limits? According to research to be published in the Open Access journal PLOS Biology on April 1, some species may be much less able to cope with the effects of climate change than previously thought. The study, by...

Advantage Held By Home Team
2013-12-10 08:59:08

Michigan State University The home team holds the advantage over visitors – at least in the plant world. However, a mere handful of genetic adaptations could even the playing field. In the current issue of the Proceedings for the National Academy of Sciences, Michigan State University researchers and their collaborators found that plant adaptation to different environments involves tradeoffs in performance. Genetic tradeoffs, in part, explain the rich diversity of species on earth....

Two Mouths For One Worm
2013-11-07 11:58:54

Max-Planck-Gesellschaft A devious evolutionary path between genetics and environment Depending on the environment in which the worm grows, the larva of the roundworm Pristionchus pacificus develops into either a wide-mouthed predator or a narrow-mouthed bacteria eater. A team of researchers at the Max Planck Institute for Evolutionary Biology in Tübingen, Germany, headed by Ralf J. Sommer have now discovered a developmental biological switch that determines the worm's mouth form....

Evolution Is Predictable Shown by Lizards
2013-07-19 10:21:14

University of California - Davis If you could hit the reset button on evolution and start over, would essentially the same species appear? Yes, according to a study of Caribbean lizards by researchers at the University of California, Davis, Harvard University and the University of Massachusetts. The work is published July 19 in the journal Science. The predictability of evolution over timescales of millions of years has long been debated by biologists, said Luke Mahler, a postdoctoral...

A new study has shed light on the potential of birds to survive in the face of climate change. In the analysis, based on more than fifty years' detailed study of a population of great tits near Oxford, UK, a team of scientists were able to make predictions about how the birds could cope with a changing climate in the future. They found that for small, short-lived birds like the great tit, evolution can work fast enough for genetic adaptation to keep pace with a changing environment. However,...

Lizards Facing Mass Extinction
2013-03-08 05:14:08

Alan McStravick for redOrbit.com - Your Universe Online One adage has held true throughout the whole of global history for every living organism on earth; When faced with a challenging situation, a species must either adapt or die. Researchers from the University of Exeter (UofE) and the University of Lincoln (UofL) believe they have discovered a dire situation for one specific species where its earlier adaptation will likely lead to its eventual death and ultimate extinction. In...

Mutant Champions Save Vulnerable Species From Almost-certain Extinction
2013-02-20 12:52:16

University of Washington Species facing widespread and rapid environmental changes can sometimes evolve quickly enough to dodge the extinction bullet. Populations of disease-causing bacteria evolve, for example, as doctors flood their “environment,” the human body, with antibiotics. Insects, animals and plants can make evolutionary adaptations in response to pesticides, heavy metals and overfishing. Previous studies have shown that the more gradual the change, the better the...

Snapshot Of Pupfish Evolution In Action
2013-01-10 15:28:17

University of California - Davis Chris Martin has bred more than 3,000 hybrid fish in his time as a graduate student in evolution and ecology at UC Davis, a pursuit that has helped him create one of the most comprehensive snapshots of natural selection in the wild and demonstrated a key prediction in evolutionary biology. "We can see a surprisingly complex snapshot of natural selection driving the evolution of new specialized species," said Martin, who with Professor Peter Wainwright...

Dinosaurs Studied To Test Cope's Rule
2012-11-03 06:05:06

Alan McStravick for redOrbit.com - Your Universe Online Before noted paleontologist and ichthyologist Edward Cope passed away in 1897, he had devised a theory that has, to this day, its proponents and detractors. His theory, known today as Cope´s Rule, stated that animals will, in their own voyage through the process of evolution, grow ever larger. This evolutionary trend has been noted across the animal kingdom. Researchers from the National Museum of Natural History (NMNH) want to...
