Evolutionary mode routinely varies amongst morphological traits within fossil species lineages
This new study uses model selection methods available only in the last several years and is an excellent example of an emerging revolution in scientific inquiry as new techniques are used to breathe new life into old data.
Hubble sees an unexpected population of young-looking stars
(Phys.org)—The NASA/ESA Hubble Space Telescope offers an impressive view of the center of globular cluster NGC 6362. The image of this spherical collection of stars takes a deeper look at the core of the ...
Ancient crocodiles ate like killer whales
(Phys.org)—Crocodiles are often thought of as living fossils, remaining unchanged since the time of the dinosaurs. But scientists have shown this is not always the case and that 150 million years ago, their ...
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 ...
Nautilus survives 500 million years -- until humans fancy it
No matter how well adapted an animal may be, it can spell evolutionary doom to have feathers or even shells that become coveted by human beings. Take the nautilus, a creature that pulled easily through the asteroid impact ...
Still capable of adapting: Researchers study genetic diversity of living fossils
The morphology of coelacanths has not fundamentally changed since the Devonian age, that is, for about 400 million years. Nevertheless, these animals known as living fossils are able to genetically adapt to their environment. ...
Scientists at NYBG add 81 new species to the catalog of plant life on Earth
The palms that Vietnamese villagers weave into hats, many varieties of lichens that depend on the pristine environment of the Great Smoky Mountains, and small, shrub-like trees that are threatened by development ...
New finding extends the range of anatomically modern coelacanths to the Early Devonian
Among sarcopterygians (lobe-finned fishes and tetrapods), coelacanths are known for their evolutionary conservatism. Epitomized by the legendary living fossil Latimeria, the distinctive body plan of anatomically ...
Research finds bright future for alternative energy with greener solar cells
(Phys.org) -- Even alternative energy technologies can sometimes be a little greener, according to a Kansas State University graduate student's research.
Paleontologists discover fossilized embryos of oldest aquatic reptiles
South American paleontologists report they have discovered fossilized embryos of the oldest aquatic reptiles, lagoon-dwelling "mesosaurs" that lived about 280 million years ago.
Protecting living fossil trees
Scientists are working to protect living fossil trees in Fiji from the impact of climate change with cutting-edge DNA sequencing technology.
Astronomy team discovers nearby dwarf galaxy
(PhysOrg.com) -- A team led by UCLA research astronomer Michael Rich has used a unique telescope to discover a previously unknown companion to the nearby galaxy NGC 4449, which is some 12.5 million light years ...
Long-held belief debunked: Cycad is not a 'Dinosaur Plant'
(PhysOrg.com) -- The widely held belief today's cycads are 'dinosaur plants' and were around during dinosaur times has been categorically debunked in a breakthrough study of international significance.
'Fossil eel' squirms into the record books
A new species of eel found in the gloom of an undersea cave is a "living fossil" astonishingly similar to the first eels that swam some 200 million years ago, biologists reported on Wednesday.
