Latest Evolution Stories
Researchers have for the first time investigated ancestry across the red fox genome, including the Y chromosome, or paternal line.
Dov Sax of Brown University and Jason Fridley of Syracuse University aren't proposing a novel idea to explain species invasiveness. In fact, Charles Darwin articulated it first. What's new about Sax and Fridley's "Evolutionary Imbalance Hypothesis" (EIH) is that they've tested it using quantifiable evidence and report in Global Ecology and Biogeography that the EIH works well.
The evolution of worms, insects, vertebrates and other “bilateral” animals from less complex creatures like jellyfish and sea anemones with “radial” symmetry may have been facilitated by the emergence of a completely new "operating system" for controlling genetic instructions in the cell.
Sticklebacks, the roaches of the fish world, are the ideal animal in which to study the genes that control body shape. They’ve moved from the ocean into tens of thousands of freshwater streams and lakes around the world, each time changing their skeleton to adapt to the new environment.
The amazing variety of human faces – far greater than that of most other animals – is the result of evolutionary pressure to make each of us unique and easily recognizable, according to a new study by University of California, Berkeley, scientists.
A well-known biologist once theorized that many roads led to Rome when it comes to two distantly related organisms evolving a similar trait.
The gravity of the world’s current extinction rate becomes clearer upon knowing what it was before people came along. A new estimate finds that species die off as much as 1,000 times more frequently nowadays than they used to. That’s 10 times worse than the old estimate of 100 times.
About 400 million years ago a group of fish began exploring land and evolved into tetrapods – today's amphibians, reptiles, birds, and mammals. But just how these ancient fish used their fishy bodies and fins in a terrestrial environment and what evolutionary processes were at play remain scientific mysteries.
Until a recent discovery by a University of Montana research lab, it was thought that cicadas had a symbiotic relationship with two important bacteria that live within the cells of its body.
One aspect of the climate change models researchers have been developing looks at how plant ranges might shift, and how factors such as temperature, water availability, and light levels might come into play.
Paleontology or Palaeontology is the scientific study of prehistoric life, including the study of fossils to determine the organisms evolution and interactions with each other and their environments. Paleontological observations have been documented as far back as 5th century BC. The science became established in the 18th century as a result of Georges Cuvier’s work on comparative anatomy, and it developed quickly within the 19th century. The term itself comes from Greek palaios, meaning...
