Human culture has changed too fast for evolution to keep up. A theory that can help explain why we respond poorly to modern conditions, despite the choices, safety and other benefits they bring, is evolutionary mismatch.

Complex, evolving systems abound in our Universe, even beyond the realms of biology.

In 1956, a teenage girl by the name of Tina Negus was summering in the United Kingdom's Charnwood Forest with her family, when she noticed a curious imprint on an overhanging rock face.

So, do thousands of fundamentalists watch plate tectonics videos and then want to listen to hymns? WTF?

Masturbation comes with a variety of health benefits that help all primates – even humans – survive and thrive, and may have helped our species evolve, according to a British study. Indeed, the practice of masturbation is something seen throughout the animal kingdom, though it is most widely associated with humans. However, the researchers behind this study believe that it is also something likely present throughout humanity's evolutionary history, present in the last common ancestor of humans, monkeys, and apes.

A new study challenges the idea that marsupials are more 'primitive' than mammals by showing their development has changed more than mammals since they last shared an ancestor.

An unusual blinking fish, the mudskipper, spends much of the day out of the water and is providing clues as to how and why blinking might have evolved during the transition to life on land in our own ancestors. New research shows that these amphibious fish have evolved a blinking behavior that serves many of the same purposes of our blinking.

A new study examining how much energy males and females spend carrying babies in different positions reported that women expend less energy carrying their babies than men in all carrying positions. Carrying a baby on one’s back was the most energy efficient and people carrying babies this way were able to maintain their unloaded walking speeds. The study was published in Evolutionary Human Sciences.

Our lifespans might feel like a long time by human standards, but to the Earth it's the blink of an eye. Even the entirety of human history represents a tiny slither of the vast chronology for our planet. We often think about geological time when looking back into the past, but today we look ahead. What might happen on our planet in the next billion years?

But they have some very compelling theories

Charles Darwin believed evolution created "endless forms most beautiful".

Two scientists explain how analyses of oxygen isotopes from ancient ape teeth could lead to new insights on early human evolution.
