Today QUEST TV broadcasts its half-hour documentary "Chasing Beetles, Finding Darwin," which tells the story of California Academy of Sciences beetle expert David Kavanaugh's unusual prediction that a new species of beetle would be found in Northern California's Trinity Alps.
The film follows Kavanaugh and his collaborator, University of California-Berkeley doctoral candidate Sean Schoville, as they search for the beetle, then put possible candidates to the test by dissecting them under the microscope and doing genetic testing on them.
It's rare for a biologist to predict the discovery of a new species – even for someone like Kavanaugh, who has discovered 73 new species. For his prediction, he drew inspiration from Charles Darwin's own prediction, which the English naturalist and founder of modern evolutionary biology made in 1862.
When Darwin saw an orchid from Madagascar with a foot-long nectare, he predicted that a pollinator would be found with a tongue (called a proboscis) long enough to reach the nectar inside the orchid's very thin, elongated nectar "pouch." Darwin's prediction was based on his finding that all living beings are related to each other and that some of them evolve closely together. His prediction came true in 1903, when a moth was discovered in Madagascar with a long, thin proboscis, which it uncurls to reach the nectar in the orchid's nectare. In the process of feeding from the orchid, the moth serves as its pollinator. The moth was given the scientific name Xanthopan morganii praedicta, in honor of Darwin’s prediction.
"Chasing Beetles, Finding Darwin" is QUEST TV's contribution to the celebration of Darwin's 200th birthday and the 150th anniversary of the publication of his book "On the Origin of Species."

At 5pm on Sunday January 6, 2008, California Academy of Sciences closed its temporary location in order to start the move back to Golden Gate Park. On September 27, 2008 the Academy will open to the public once again in its new home in the Park. Many curious museum-goers have asked, why the long gap between closing and opening? 265 days is long time to move across town.
What is on the public floors of the museum is just the tip of the iceberg of the Academy's collections. Over a span of more than 150 years, the Academy has built an invaluable collection that acts as a strong backbone for the museum. Twenty million research specimens and 38,000 live animals have to be carefully packed and transported. The Academy is undertaking the most massive move ever undertaken by a museum.
The Botany collection was the first to move out of Howard Street. It took only eleven and a half days to move two million specimens. For perspective, it took 61,300 cardboard inserts bundled with over 40 miles of twine to bundle the flora. Botany is only one of eight Academy research departments preparing to move.
The Academy's packing list is as varied as its research. Ornithology and Mammalogy have to transport Monarch, the last Grizzly bear of California. Because of its size and girth, it will not be boxed. However, it will take several movers to transport it carefully. Monarch will be joined by 30,000 other mammal specimens, including study pelts, skulls, skeletons, and the world's largest collection of marine mammal specimens.
It will be even more challenging to move the Academy's live animals. 38,000 live animals will be moved, water included, back to the Park in tanks of varying sizes. One of the aquarium's Australian Lungfish will be the oldest living animal to move. Over seventy years old, this fish has seen the Academy through many changes– a move to Howard Street, and now the move back to Golden Gate Park.
The Academy's Galápagos collection will also be packed up. It features thousands of Geospizine Finches (the group studied by Darwin) and the world's largest collection of reptiles from the Galápagos.
Cultural keepsakes will be preserved. Pre-Columbian Inca clothing, 12th Century Persian ceramics, fragile feather leis, full-sized Native Alaskan kayaks, 500 Japanese folk toys, and a renowned collection of eating utensils will also find their home in Golden Gate Park.
To give you a sense of the immensity of the project, 20 million specimens include the following:
- Over 200,000 fish specimens preserved in alcohol, including a rare coelacanth (thought to be extinct until discovered in the 1930s);
- 14.5 million insects and arachnids, including more than 874,789 flies, some 524,666 true bugs, nearly 3 million beetles, and more than 700,000 butterflies and moths;
- Nearly 100,000 bird specimens, including the now-extinct Guadalupe Storm Petrel and 10,600 sets of bird nests and eggs;
- More than a quarter of a million reptiles and amphibians from 166 countries.
The sheer volume of this move makes it a migration. Over 20 million specimens can not be moved in a day. It will take every one of those 265 days to move and prepare to share the wealth of the Academy once again with the public.
