The Grant Museum’s current exhibition – The Museum of Ordinary Animals: The Boring Beasts that Changed the World ­­- explores the mundane creatures in our everyday lives. Here on the blog, we will be delving into some of the stories featured in the exhibition with the UCL researchers who helped put it together.

In many animals, females are pickier about choosing their mates than males are, since they invest more in their offspring than males do. By choosing high quality mates, females give their offspring a good chance of inheriting their fathers’ beneficial traits. This will help the young in their own search for mates, thereby increasing the chances that the original female’s genes will be passed down through the generations.

Dominant males have all the things that turkey hens want, including long snoods and vibrant wattles.

In all species, some individuals are simply better looking than others, and they have the right shape, colour or attitude that makes them irresistible to the opposite sex of their species. Scientists have generally assumed that good looks come primarily from good genes, but this presents an enigma: if only individuals with the best genes pass them on in every generation, those sexy genes should spread and soon the entire population should be equally attractive.

So… how is that unattractive genes persist in populations? Why doesn’t evolution wipe them out? (more…)

‘Natural Creativity: Sex and Trickery’ is our new exhibition – opening tomorrow 19th October –  at the Grant Museum. It explores the myriad of elaborate shapes, sizes and crafty behavioural tactics some animals have evolved in order to survive, reproduce and pass on their genes.

Through intricate drawings by the artist Clara Lacy, ‘Natural Creativity’ asks the question, why is the natural world so colourful and varied? Lacy has drawn species with highly unusual sexual behaviours or mechanisms for determining sex. It is commonly assumed that animals are born either male or female then reproduce as adults, but things can get much more interesting. Some species change sex over their lifetime, become a grandmother before giving birth, or trick others into thinking they belong to the opposite sex.

Ocellated wrasse (C) Clara Lacy.
The ocellated wrasse has an unusual mating system – different males use different strategies in the attempt to pass on their genes. The genetics of these strategies is being researched at UCL. “Nesting males” are brightly coloured and work to court females, defend nests and care for their young. These males attract the most females, but other males have evolved different routes to mating success.
Small males become “Sneakers”. They surreptitiously approach Nesting males and females while they are mating, and then release their own sperm into the water.
Medium-sized “Satellite males” cooperate with a Nesting male, helping them chase Sneakers from the nest. This means that they are tolerated by Nesting males, and spawn while the Nesting male is mating.

Hi, I’m Paolo and this is my first blog post as Curator of the Grant Museum of Zoology, picking up the reins from Mark Carnall. I’ve chosen this specimen of the week based simply on the fact that it has very interesting cheeks – or ‘zygomatic plates’ if you speak zoologese.

Bentham later in life.

On February 14^th (yes, Valentine’s day) I will be giving a short talk at ‘Late London: City of Seduction’, part of the Museum of London’s special events program, on the auto-icon of Jeremy Bentham. I will be introducing the auto-icon, discussing how it was made and talking about some of the legends that have built up around it (head used for a game of football anyone?). I will then relinquish the floor to Professor Philip Schofield, head of the Bentham Project, an expert of Bentham’s life and works.

So, a dead Philosopher, a mummified head and an articulated skeleton don’t sound very suitable for Valentine’s day do they? And maybe they aren’t, however if you look closer at the philosophy Bentham helped found…

The Petrie Museum’s Fit Bodies Exhibition on display in the Museum and North Cloisters is drawing to a close (in the Cloisters space) and, whilst I will be happy to get my trusty wooden lacrosse stick back, I am sad this exhibition is ending. Fit Bodies has included a variety of elements, from photographic competitions to theatrical performances in a light-hearted take on the notion of ‘fit’, an adjective accredited to sporting prowess as well as sexual appeal. However, one notion I realised only after giving a seminar on the exhibition, was this expectation of the elite to be attractive, in particular I think of the recent sportsmen and women who have proved their value through trial, tribulation, yet are still presented on that sordid platter of sexuality.
