3D simulation shows how form of complex organs evolves by natural selection
Researchers at the Institute of Biotechnology at the Helsinki University and the Universitat Autònoma de Barcelona (UAB) have developed the first three-dimensional simulation of the evolution of morphology by integrating ...
The ethics of resurrecting extinct species
(Phys.org) —At some point, scientists may be able to bring back extinct animals, and perhaps early humans, raising questions of ethics and environmental disruption.
Novel way plants pass traits to next generation found: Inheritance behavior in corn breaks accepted rules of genetics
New research explains how certain traits can pass down from one generation to the next – at least in plants – without following the accepted rules of genetics.
Risk management in fish: How cichlids prevent their young from being eaten
For a variety of reasons, many humans choose to adopt children. More surprisingly, adoption is fairly widespread in the animal kingdom, even though it would seem to counteract the basic premise of Darwin's ...
Suicidal bacteria: Biologists study unicellular organisms that occasionally poison themselves with a toxin
The cyanobacterium Synechocystis produces toxins that often lead to its own demise. The biologists Stefan Kopfmann and Prof. Dr. Wolfgang Hess from the University of Freiburg have determined the logic governing ...
Researchers show gene controlling coat color in mice mutated nine times, results shed new light on how evolution works
For deer mice living in the Nebraska Sandhills, color can literally be the difference between life and death.
Dead seals serve conservation boost
Scientists have used genetic testing on animals that died of natural causes for the first time, potentially boosting efforts to save endangered species.
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.
Accelerating cellular assembly lines
The immune system generates antibodies to mark threats that need to be eliminated, and these protein complexes bind their targets with remarkable strength and selectivity. Scientists have learned how to generate ...
DNA tests show Lonesome George may not have been last of his species
(Phys.org)—When the giant tortoise Lonesome George died this summer, conservationists from around the world mourned the extinction his species. However, a genetic analysis by Yale University researchers ...
Genomics analysis demonstrates natural selection at work
(Phys.org)—A team of researchers at Michigan State University has documented the step-by-step process in which organisms evolve new functions.
Picky penguins: Does mate choice depend on genes that help resist disease?
Magellanic penguins have a high level of variation in genes associated with the ability to fight infectious disease, but a recent study found that the mechanism the penguins use to ensure that diversity is ...
For the rooster, size matters—Pleiotropic genes affect comb size and egg production
A lone rooster sees a lot of all the hens in the flock, but the hen with the largest comb gets a bigger dose of sperm - and thus more chicks. This sounds natural, but behind all this is humanity's hunger ...
Nanotechnology-enhanced DNA analysis
European researchers enhanced the selectivity of state-of-the-art genetic sequencing methods using nanotechnology. Immediate application in detection of strains of Salmonella and Staphylococcus should facilitate ...
