Dune flies have 41 different dance moves. Changing even one of them is rarer than you’d think.

Compared to other great apes, human penises are mysteriously large, hinting they act as a signal to mates.
Most primate societies do not have clear-cut sex-biases when it comes to power.
A secret under-layer explains why songbirds’ colourful feathers look so damn good.
Males and females differing in body size is a common outcome of sexual selection.
A better brain might help an animal find more mates, have more sex, and eventually have more babies.
A new study modelled how a game of snog, marry, avoid, may play out in the animal kingdom.
Birdsong plays a vital social role in the lives of these gregarious finches.
People don’t randomly select who they have children with. And that means an underlying assumption in research that tries to link particular genes to certain diseases or traits is wrong.
We’ll probably be less aggressive and more agreeable, but have smaller brains – a bit like a Golden Retriever, we’ll be friendly, but maybe not that interesting or bright.
The lack of large numbers of fossils makes it hard to study sexual dimorphism in dinosaurs. But a new statistical approach offers insight into this question and others across science.
The sexual selection of larger males may be driven by an abundance – not a scarcity – of females.
In the television show ‘The Handmaid’s Tale,’ Charles Darwin’s ‘Descent of Man’ makes a cameo — and its appearance makes a comment on how Gilead functions.
Scientists don’t ask how some people evolved to be tall. In the same way, asking how homosexuality evolved is the wrong question. We need to ask how human sexuality evolved in all its forms.
Scientists don’t just want to unravel the mysteries of slug sex for voyeurism.
Studies suggest a significant proportion of Indian-origin families in Canada are practising female feticide. It is crucial to understand how gender inequality may lead to sex selection.
The Australian right-to-life movement is tiny compared to the US, but its recent adoption of US-style campaign strategies has given it an outsize voice in the debate here.
New evidence boosts the idea that species with males who compete for mates adapt faster to changing circumstances.
Biologists investigated whether birds that search for multiple mates would evolve ever more elaborate songs to attract them. What they found might have surprised Darwin.
Why are humans the only animals with chins?
