Dating Mammalian Evolution

Fri, 28 Mar 2014 15:14:37 +0000

When the age of the dinosaurs ended around 65 million years ago, mammals stepped in to fill the gap, and the age of the placentals began. However, whether early placental mammals were already present on Earth before the demise of the dinosaurs has been the subject of a long standing debate. Recent research in GEE [...]

The Delicate Balance of Effect and Response

Tue, 18 Feb 2014 11:50:36 +0000

We may not always be aware of it, but many wild plants, animals, fungi and even bacteria, provide crucial services to us which keep the ecosystems of Earth functioning. Environmental changes caused by human activities are now threatening many species, and those that cannot withstand these changes may be lost forever, potentially taking the services [...]

It’s All in the Wrist

Fri, 20 Dec 2013 16:18:20 +0000

The evolution of the primate wrist has been dramatic, enabling primates to adapt to a wide variety of lifestyles and walking styles, including tree-swinging, climbing and terrestrial walking both on four legs and two. In hominids, the evolution of the bipedal gait freed up the forelimbs for tool use, and the wrist evolved independently from [...]

The Transcriptional Profile of A ‘Wingman’

Wed, 27 Nov 2013 14:25:48 +0000

In many species, males have special adaptations to attract females. From antlers to stalk-eyes, to bright plumage and beards, males across the animal kingdom work hard to look attractive to the opposite sex. In some species, looking good isn’t enough, though. Male wild turkeys need a less attractive ‘wingman’ to help him attract a woman. [...]

Damage and Fidelity: The Role of the Female Germline in mtDNA Inheritance

Mon, 11 Nov 2013 15:13:12 +0000

Billions of years ago, one single-celled organism engulfed another, beginning a symbiotic interaction that would change live on Earth forever. The mitochondria are what remains of this symbiotic event, and are responsible for producing energy in all eukaryotic cells. Derived from a free-living organism, they carry their own genes, but these genes are at risk [...]

A Crucial Difference: Celebrating Diversity in Nature

14 May 2010

7th April to 30th June 2010

North Cloisters, Main Building, Gower Street, UCL, WC1E 6BT

As part of the 2010 International Year of Biodiversity, UCL Museums & Collections have organised an exhibition celebrating the diversity with our collections.

The four cases contain sets of objects from two natural history collections at UCL – the Grant Museum of Zoology and UCL Geology Collections. At first glance each object may appear to be the same.

In natural history there are no duplicates – every specimen is unique. For students and researchers at UCL, the existence of several examples of the same specimen type is crucial to the way their subjects are taught and studied. For a scientific theory to be tested many samples must be collected and analysed. It is only by understanding the variation within a group that its limits can be determined, and its relationships described.

2010 is the International Year of Biodiversity. Biodiversity, the variety of life on Earth, is essential to sustaining the living systems that provide us with health, wealth, food, fuel and the vital services on which our lives depend. This exhibition celebrates some of that variety.
