Calculating evolution: Program predicts the development of influenza viruses
For a long time, prognoses forecasting the evolutionary future of organisms were considered mere speculation. Together with researchers from Cambridge and Santa Barbara scientists at the Max Planck Institute ...
Researchers test whether Red Queen hypothesis makes species resilient
In Lewis Carroll's 1871 classic novel Through the Looking Glass, the Red Queen tells Alice: "Now, here, you see, it takes all the running you can do, to keep in the same place."
Environmental complexity promotes biodiversity
A new study published in the journal American Naturalist helps explain how spatial variation in natural environments helps spur evolution and give rise to biodiversity.
Fungal sex can generate new drug resistant, virulent strains
Though some might disagree, most biologists think the purpose of sex is to create diversity among offspring. Such diversity underpins evolution, enabling organisms to acquire new combinations of traits to ...
Death by asexuality: Biologists uncover new path for mutations to arise
Ground-breaking new research from a team of evolutionary biologists at Indiana University shows for the first time how asexual lineages of a species are doomed not necessarily from a long, slow accumulation ...
Diatom sex pheromone isolated and characterized
(Phys.org)—Diatoms (unicellular photosynthetic organisms) reproduce through asexual cell division alternating with short periods of sexual reproduction. A German and Belgian team has now determined that ...
Researcher argues that sex reduces genetic variation
Biology textbooks maintain that the main function of sex is to promote genetic diversity. But Henry Heng, Ph.D., associate professor in WSU's Center for Molecular Medicine and Genetics, says that's not the case.
Girl power: Female boa constrictor doesn't need a male
In a finding that upends decades of scientific theory on reptile reproduction, researchers at North Carolina State University have discovered that female boa constrictors can squeeze out babies without mating.
Study shows how ancient plants and soil fungi turned the Earth green
A new breakthrough by scientists at the University of Sheffield has shed light on how the Earth's first plants began to colonise the land over 470 million years ago by forming a partnership with soil fungi.
Biologists identify influence of environment on sexual vs. asexual reproduction
Evolutionary biologists at the University of Toronto have found that environment plays a key role in determining whether a species opts for sexual over asexual reproduction.
Can clonal plants live forever?
Despite the many cosmetic products, surgical treatments, food supplements, and drugs designed specifically to reverse the biological effects of aging in humans, long-lived aspen clones aren't so lucky. Researchers at the ...
Asexual plant reproduction may seed new approach for agriculture
An HHMI scientist has moved a step closer to turning sexually-reproducing plants into asexual reproducers, a finding that could have profound implications for agriculture.
Rotifers avoid sex for millions of years by blowing away
(PhysOrg.com) -- They haven't had sex in some 30 million years, but some very small invertebrates named bdelloid rotifers are still shocking biologists - they should have gone extinct long ago. Cornell researchers ...
Study shows value of sexual reproduction versus asexual reproduction
Living organisms have good reason for engaging in sexual, rather than asexual, reproduction according to Maurine Neiman, assistant professor of biology in the UI College of Liberal Arts and Sciences and researcher in the ...
