A study in the journal Cell sheds new light on the evolution of neurons, focusing on the placozoans, a millimetre-sized marine animal. Researchers at the Centre for Genomic Regulation in Barcelona find evidence that specialized secretory cells found in these unique and ancient creatures may have given rise to neurons in more complex animals.

The European starling boasts a remarkable repertoire. Versatile songbirds that learn warbles, whistles, calls, and songs throughout their lives, starlings rank among the most advanced avian vocal learners. Now a new study published in Science finds that starlings, along with other complex vocal learners, are also superior problem solvers.

More than 100 ancient paintings and engravings, thought to be at least 24,000 years old, have been found in a 500-meter-long cave in “Cova Dones” or “Cueva Dones”—a site located in Millares near Valencia in Spain. See the research here.

A team of researchers has just uncovered another striking connection between math and nature: between one of the purest forms of mathematics, number theory, and the mechanisms governing the evolution of life on molecular scales, genetics. See the study here.

Research led by Complutense University, Madrid, has discovered an array of ancient cave paintings hidden among previously described cave art. In a paper, “Animals hidden in plain sight: stereoscopic recording of Paleolithic rock art at La Pasiega cave, Cantabria,” published in Antiquity, the team fills in details missing from previous photographic images.

A new fossil ape from an 8.7-million-year-old site in Türkiye is challenging long-accepted ideas of human origins and adding weight to the theory that the ancestors of African apes and humans evolved in Europe before migrating to Africa between nine and seven million years ago. See the study here.

In a new study, published in August 2023, we sought to understand changes that were happening in California during the last major extinction event at the end of the Pleistocene, a time period known as the Ice Age.

Archaeologists in Germany have discovered the missing piece of an ice age carving deep in a cave. But the new addition of the ivory carving, originally thought to depict a horse, has actually complicated matters: Now, researchers aren’t sure if it portrays a cave lion or a cave bear.

The new species, which has been named Burgessomedusa phasmiformis,resembles a large, swimming jellyfish with a saucer or bell-shaped body up to 20cm high. Its roughly 90 short tentacles would have allowed it to capture sizeable prey.

Scientists said on Friday they have genetically engineered female fruit flies that can have offspring without needing a male, marking the first time ‘virgin birth” has been induced in an animal. See the study here.

Experts revealed the 125m-year-old fossil that froze in time after being taken on by a small mammal a third of its size. They are tangled together, the mammal’s teeth sunk into the beaked dinosaur’s ribs, its left paw clasping the beast’s lower jaw. See research here.

New research suggests humans lived in South America at the same time as now extinct giant sloths, bolstering evidence that people arrived in the Americas earlier than once thought.

A pod in the strait of Gibraltar has sunk three boats and damaged dozens of others, and their story has captivated the world. What explains this unprecedented behaviour?

Hunter-gatherer roles in human society are not nearly as gendered as anthropologists and archaeologists have traditionally believed, with narratives of ‘man the hunter’ and ‘woman the gatherer’ crumbling in the face of new evidence. The study was published in PLOS ONE.

Bottlenose dolphin moms modify their individually distinctive whistles when their babies are nearby, researchers report June 26 in the Proceedings of the National Academy of Sciences. This “parentese” might enhance attention, bonding and vocal learning in calves, as it seems to do in humans.
