A little-known species of tropical bee has evolved an extra tooth for biting flesh and a gut that more closely resembles that of vultures rather…
Understanding resistance rates and cross-resistance can improve the potency of sequential antibiotic treatment protocols. Sequential treatment using antibiotics that are similar but swapped around frequently…
Leaves display a remarkable range of forms from flat sheets with simple outlines to the cup-shaped traps found in carnivorous plants. A general question in…
There are way more species of horseshoe bats than scientists thought. If you’ve never seen a horseshoe bat, you’re missing out. Their comically large ears…
Fossilized flies that lived 54 million years ago have revealed a surprising twist to the tale of how insects’ eyes evolved. These craneflies, unveiled in…
About 400 million years ago, vertebrates first began to crawl from the primordial seas onto land. Last week, thanks to a cutting-edge mathematical-analysis technique, a…
An international team of researchers has uncovered the remains of a new species of human in the Philippines, proving the region played a key role…
The Genetics of Regeneration When it comes to regeneration, some animals are capable of amazing feats. If you cut off a salamander’s leg, it will…
Scientists have reproduced in the lab how the ingredients for life could have formed deep in the ocean 4 billion years ago. The results of…
The human brain owes its characteristic wrinkled appearance to its outer layer, the cerebral cortex. During human evolution, the neocortex, the evolutionarily youngest part of…
A new study says the colors found in modern birds’ eggs did not evolve independently, as previously thought, but evolved instead from dinosaurs. According to…
How did life arise on Earth? Rutgers researchers have found among the first and perhaps only hard evidence that simple protein catalysts – essential for…
New archaeological research from The Australian National University (ANU) has found that Homo erectus, an extinct species of primitive humans, went extinct in part because…
A new study argues that the greatest defining feature of our species is not ‘symbolism’ or dramatic cognitive change, but rather its unique ecological position…
