Fiddler crabs are strange little beasties. Males have what amounts to one giant claw, which can be as long as his body is wide, and one tiny T. rex arm that looks quite out of place on a crab. Recently, a researcher wrote a blog post about why fiddler crabs have such an enormous claw [...]

Lizard Females That Look Like Males Are Less Attractive (to Male Lizards)

A male fence lizard

In many species, male and females look different to each other. In these ‘sexually dimorphic’ species, males tend to be more ornamented. ‘Ornaments’ are basically anything that’s just for decoration with no other function, the classic example being the peacock’s tail.   Female and male humans are sexually dimorphic, but a lot less so than [...]

Why the Best Male Doesn’t Always Win

NORMAN, Okla.—Survival of the fittest really boils down to reproduction of the fittest. If an animal can survive long enough to pass on its genes to a new generation, it has won out in the evolutionary competition.

Dinosaurs and their ‘exaggerated structures’: species recognition aids, or sexual display devices?

Mesozoic dinosaurs of several lineages famously possessed horns, frills, bony bosses, crests, frills, blah blah blah – you’ve heard all this a million times before. Pterosaurs were flamboyant creatures too. Why did these animals possess these so-called exaggerated structures?

Sexual selection in the fossil record

The sexy sabercat: how the sabertooth got its teeth

Skull of Homotherium crenatidens in the Muséum national d'Histoire naturelle in Paris.

Many sabertooths have stalked this world. The first sabertoothed mammals appeared over 50 million years ago. The last sabercats, such as Smilodon and Homotherium, went extinct only 10.000 years ago. All in all, five different lineages of carnivorous mammals evolved sabertooth dentition: the ancient creodonts, marsupials and three different lineages of true cats and cat-like [...]

Book review: Survival of the Beautiful

Sometimes all you have to do to make me buy your book, is think of a good title. Survival of the Beautiful by David Rothenberg definitely did the trick. “No one ever mentions the beautiful”, I thought when I took the book from its shelf in a London book store. Not when it comes to [...]
