Lizard moms choose the right genes for the right gender offspring
(PhysOrg.com) -- Two Dartmouth biologists have found that brown anole lizards make an interesting choice when deciding which males should father their offspring. The females of this species mate with several ...
Long-tailed tits help each other out
Long-tailed tits which lose their eggs or young may help to feed neighbours' chicks, researchers have found. But the degree to which they'll co-operate varies from year to year.
Genetic similarity promotes cooperation
In a dog-eat-dog world of ruthless competition and 'survival of the fittest,' new research from the University of Leicester reveals that individuals are genetically programmed to work together and cooperate ...
New research indicates that DNA sequence itself influences mutation rate
Genetic variation due to DNA mutation is a driving force of adaptation and evolution, as well as a contributing factor to disease. However, the mechanisms governing DNA mutation rate are not well understood. In a report ...
Meet the beetles: Social networks provide clues to natural selection
Think of them as a group of guys, hanging out together, but not spending much time with the ladies, nor getting much "action." Except these "guys" are forked fungus beetles.
Rapid evolution of novel forms: Environmental change triggers inborn capacity for adaptation
In the classical view of evolution, species experience spontaneous genetic mutations that produce various novel traits—some helpful, some detrimental. Nature then selects for those most beneficial, passing ...
Age doesn't matter: New genes are as essential as ancient ones
New genes that have evolved in species as little as one million years ago a virtual blink in evolutionary history can be just as essential for life as ancient genes, startling new research has discovered.
Potential carbon capture role for new CO2 absorbing material
(Phys.org) -- A novel porous material that has unique carbon dioxide adsorption properties has been developed through research led by The University of Nottingham.
Research finds clue to why females live longer than males
A study from the University of Exeter has found that male flies die earlier than their female counterparts when forced to evolve with the pressures of mate competition and juvenile survival. The results could ...
Study: Self-delusion may be a winning survival strategy
Harbouring a mistakenly inflated belief that we can easily meet challenges or win conflicts is actually good for us, a new study suggests.
A snapshot of pupfish evolution in action
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 ...
Mice living in sandy hills quickly evolved lighter coloration
In a vivid illustration of natural selection at work, scientists at Harvard University have found that deer mice living in Nebraska's Sand Hills quickly evolved lighter coloration after glaciers deposited ...
Evolution of new genes captured
(Phys.org)—Like job-seekers searching for a new position, living things sometimes have to pick up a new skill if they are going to succeed. Researchers from the University of California, Davis, and Uppsala University, Sweden, ...
Networking ability a family trait in monkeys
Two years of painstaking observation on the social interactions of a troop of free-ranging monkeys and an analysis of their family trees has found signs of natural selection affecting the behavior of the descendants.
