Unknown Species

What about all the others?


Most people can tell the difference between some types of berries, or bugs or trees, but much of the planet's life remains unnamed and unseen.

A stunningly egotistical Swedish naturalist, Carl Linnaeus, tried long ago to set humanity on track to remedy that. 

His book, "Systema Naturae," first published in 1735 at 13 pages long, proposed a hierarchical system for classifying plants, animals and minerals (we later chipped away minerals into the domain of geology) and launched an effort to identify and inventory all the world's living things.

Now 250 years after publication of the book's latter editions, scientists still have discovered as few as 10 percent of the species now living on Earth, said Harvard biologist Edward O. Wilson, who spoke here last week at an event at the New York Botanical Garden to celebrate a visit of Linnaeus' personal copy of the book's first edition.

"We live, in short, on a little-known planet. When dealing with the living world, we are flying mostly blind,"
Wilson said. 


"When we try to diagnose the health of an ecosystem, such as a lake or a forest, in order to save and stabilize it we are in the position of a doctor trying to treat a patient, knowing only 10 percent of organs."

Linnaeus' launch of a global inventory of life was one of his most influential contributions to science, said Wilson, a proponent of a recent, similar contemporary effort, the "Encyclopedia of Life," an online reference source and database for the 1.8 million species known on Earth, as well as all those later discovered and described. The Encyclopedia is designed to help scientists, educators, students and the public gain a better understanding of the planet's inhabitants.


What are they doing?

Today, biologists are attempting to finally complete the Linnaean enterprise, a full mapping of Earth's biodiversity pole to pole, bacteria to whales, at every level of biological organization from the genome to the ecosystem,
Wilson said.

The "Encyclopedia of Life" aims to yield "a cause and effect explanation of the biosphere and the correct and verifiable family tree for all of the millions of species," he said. 

"In short, it aims to undergird a unified biology which I believe will be the great achievement of the 21st century, the age of synthesis that we have now entered."

For instance, the number of species of nematodes or roundworms, the most abundant animals on Earth, stands at about 16,000 species known, but the numbers of actual species could run into the millions, experts estimate.

"And we have to ask, 'What are they doing?'" he told the chuckling audience. "I mean, if we don't even know what they are yet, but we know they are there in vast variety and enormous abundance, then clearly they must be doing something important in the ecosystems that are the foundation of our own life."

Biologists are grateful,
Wilson said, to the memory of Linnaeus, "who led the way in the systematic exploration of life on this planet, which we must now, for the good of the planet and humanity, hurry up to finish."
