Do bacteria age? Biologists discover the answer follows simple economics
When a bacterial cell divides into two daughter cells and those two cells divide into four more daughters, then 8, then 16 and so on, the result, biologists have long assumed, is an eternally youthful population of bacteria. ...
Did the universe evolve to make black holes?
(Phys.org) —The maths underpinning Darwin's theory of natural selection could explain how the universe may be 'designed' to make black holes.
Evolution may take giant leaps
Ancient penguin DNA raises doubts about accuracy of genetic dating techniques
Penguins that died 44,000 years ago in Antarctica have provided extraordinary frozen DNA samples that challenge the accuracy of traditional genetic aging measurements, and suggest those approaches have been ...
Study of giant viruses shakes up tree of life
A new study of giant viruses supports the idea that viruses are ancient living organisms and not inanimate molecular remnants run amok, as some scientists have argued. The study reshapes the universal family ...
Molecular Decay of Enamel-Specific Gene in Toothless Mammals Supports Theory of Evolution
(PhysOrg.com) -- Biologists at the University of California, Riverside report new evidence for evolutionary change recorded in both the fossil record and the genomes (or genetic blueprints) of living organisms, ...
Study shows humans still evolving
Resurrected mammoth blood very cool (w/ Video)
(PhysOrg.com) -- A team of international researchers has brought the primary component of mammoth blood back to life using ancient DNA preserved in bones from Siberian specimens 25,000 to 43,000 years old.
Dogs likely originated in the Middle East, new genetic data indicate
Dogs likely originated in the Middle East, not Asia or Europe, according to a new genetic analysis by an international team of scientists led by UCLA biologists. The research, funded by the National Science ...
Hidden soil fungus, now revealed, is in a class all its own
A type of fungus that's been lurking underground for millions of years, previously known to science only through its DNA, has been cultured, photographed, named and assigned a place on the tree of life.
Advantages of living in the dark: The multiple evolution events of 'blind' cavefish
The blind Mexican cavefish (Astyanax mexicanus) have not only lost their sight but have adapted to perpetual darkness by also losing their pigment (albinism) and having altered sleep patterns. New research publis ...
Castaway lizards provide insight into elusive evolutionary process
A University of Rhode Island biologist who released lizards on tiny uninhabited islands in the Bahamas has shed light on the interaction between evolutionary processes that are seldom observed.
Largest group of fossil humans are Neanderthals after all
(Phys.org) -- The world's largest known sample of fossil humans has been classified as the species Homo heidelbergensis but in fact are early Neanderthals, according to a study by Prof Chris Stringer of the ...
New brain gene gives us edge over apes, study suggests
Scientists have taken a step forward in helping to solve one of life's greatest mysteries – what makes us human?
