A Handful Of Bronze-Age Men Could Have Fathered Two Thirds Of Europeans

Europe has surprisingly little genetic variety. Learning how and when the modern gene-pool came together has been a long journey. But thanks to new technological advances a picture is slowly coming together of repeated colonization by peoples from the east with more efficient lifestyles. » 5/22/15 3:00pm Yesterday 3:00pm

This Prehistoric Pocket Deer Has Fewer Chromosomes Than A Fruit Fly

Meet the muntjac — the most interesting deer in the world.

Here's What Sharks Do When You Give Them Cameras

You're Looking at an Insect Penis Inside its Mate

One of the biggest challenges for scientists studying the anatomy and physiology of genitalia is the fact that much of the real functional action happens deep inside females. It’s hard to see what’s going on in there. That’s why I love studies that rise to the challenge of giving us a peek inside. » 5/15/15 6:30pm 5/15/15 6:30pm

Deceptive Photo Makes This Eel Look Taller Than A Double Decker Bus

Fishermen working off the coast of Plymouth in Britain snagged a 7-foot-long (2.1 meters) conger eel by mistake after it got tangled in their nets. Weighing in at just over 133 pounds (59 kg), it’s a near-record catch — but this clever optical illusion makes it look much longer than it really is. » 5/15/15 6:30am 5/15/15 6:30am

Now prehistoric mammals — that’s where the action is. Here are the top 10 mammals that ruled more than any dinosaur ever. » 5/14/15 10:00am 5/14/15 10:00am

Darwin Predicted This Animal's Existence Decades Before Its Discovery

Here’s a great Charles Darwin story you may not have heard before: In 1862, the famed naturalist foretold the discovery of an unusual animal, based on his observations of a species of orchid endemic to Madagascar. The creature was ultimately discovered in 1903—some 20 years after Darwin’s death. » 5/13/15 12:00pm 5/13/15 12:00pm
