A flea that's been frozen in time may possess bacteria that's the ancestor of the Black Death. Scientists have discovered a flea preserved in amber with tiny bacteria that could have eventually evolved into the dreaded strain of the bubonic plague.
It turns out that Australia's first human residents may have had to deal with giant, killer lizards. Scientists have found that Australia's early human inhabitants and giant apex predator lizards actually overlapped.
Scientists have uncovered a new lineage of extinct sharks that didn't eat meat, but instead feasted on plankton. The sharks once lived in warm oceans during the age of the dinosaurs, nearly 100 million years ago.
Researchers may have found specimens of Africa's earliest known coelacanth. The creature is dated to be about 360 million years old, and was discovered in South Africa's Eastern Cape.
A group of scientists have discovered that a mysterious "living fossil" may not have changed much on the outside, but it's definitely evolved genetically.
Scientists have released the "tree of life" for a staggering 2.3 million named species of animals, plants, fungi and microbes.
Scientists may have just discovered the earliest animal to have walked upright on all-fours.
You don't want to get near one of these snakes.
Millions of years ago, our early ancestors shifted from a diet based on trees to a diet based on grasses. Now, scientists have taken a closer look at this shift.
Imagine watching evolution in real time. That's what a group of researchers are doing in an ongoing effort the record the interaction of the environment and evolution. They've monitored a population of guppies in order to better understand the process of evolution.
Researchers have taken a closer look at evolution and have found how these structural differences could arise in two species with nearly identical genetic backgrounds.
