Reasoning Trailblazer: Paul D. N. Hebert

Learning Outcomes

By the end of this section, you will be able to:

  • Read for inquiry, learning, and critical thinking.
  • Identify reasoning strategies and explain their functions.

“[R]esearchers will find a barcode linked to just about anything… encountered anywhere on the planet.”

Reasoning Strategies in Science

Born in Kingston, Ontario, Canada, Paul Hebert (b. 1947) earned his bachelor of science degree from Queen’s University, a public research university in his hometown. He then pursued graduate studies at the University of Cambridge (United Kingdom), where he received his PhD in genetics (a branch of biology dealing with heredity and the variation of inherited characteristics). He spent three years at Sydney University in Australia and then another year in London at the Natural History Museum. Returning to Canada, he began research at the University of Windsor, followed by a directorship at the Great Lakes Institute at Windsor. In 1990, he joined the faculty of Ontario’s University of Guelph, where he became director of the Centre for Biodiversity Genomics (a branch of biotechnology that strives to apply concepts of genetics and molecular biology to genetic mapping and DNA sequencing), and he holds a Canada Research Chair in molecular biodiversity (the study of the variety of life found on Earth or in a particular place on Earth).

Interestingly, Dr. Hebert, a well-known genetic scientist, uses reasoning strategies to organize his research. In 2019, a team he led launched a multimillion-dollar effort to identify more than two million new species of creatures. Because the world is losing species faster than species are being discovered, his initiative comes at an opportune time and adds to the value of his work. Experts in the field of biodiversity estimate that Earth is home to 8.7 million to 20 million different kinds of plants, animals, and fungi. To date, however, only 1.8 million of them have been formally described.

In 2003, Dr. Hebert first proposed the concept of using DNA (abbreviation for deoxyribonucleic acid, which codes genetic information for the transmission of inherited traits from a specimen) to create what is called DNA barcoding. This strategy is a method of identifying and classifying species by using a specific section of genetic code. In his groundbreaking paper, he proposed DNA barcoding as a solution to differentiate species by using the same small piece of DNA for every organism. A similarity today is the way in which scanners at groceries and other stores use UPC barcodes on items to determine prices.

The idea behind the barcode thinking is that it creates a unique sequence that can be used in myriad ways. Two of these ways include identifying an organism as part of a larger species and identifying a previously unknown species. Hebert proposed that animal species could be distinguished by sequencing fewer than 1,000 bases of mitochondrial (dealing with a subcellular structure found in many organisms) DNA from a given specimen.

Dr. Hebert was the founding director of the Biodiversity Institute of Ontario. Its goals are to

  • advance the knowledge of what makes up biodiversity;
  • protect biodiversity; and
  • help boost the global collaboration of biodiversity researchers.

In addition to his work with the Biodiversity Institute of Ontario, Dr. Hebert heads the International Barcode of Life, which began in 2008 as a reference library of known species with their identifying sequences. The barcodes have helped identify organisms and document how they interact with other species.

One research program of the International Barcode of Life is BIOSCAN. BIOSCAN’s areas of research are threefold. The first is to speed the discovery of species. BIOSCAN will use new means to increase the identification of the millions of species yet to be discovered by analyzing hundreds of millions of specimens from freshwater, saltwater, and land sources. The second area is interaction of species, which will investigate the complex ecosystem of species, a topic that, for the most part, remains shrouded in mystery. The third area is species dynamics, which will study many of the world’s areas as they are defined by their environmental conditions. Researchers will use that data to compile comprehensive starting points for comparisons about biodiversity.

In its ongoing efforts, BIOSCAN hopes to more than double the reference library, using specimens and species interactions at 2,500 sites around the world, a nod to the international impact of DNA technology. Almost all the new barcode records will come from undescribed species. A primary goal will be discovery of species. A sample barcode sequence will be taken. If it does not match an existing species, researchers will examine the specimen more closely, hoping to find a new species. In the past, this process would have taken years before a specimen was, indeed, confirmed as a new species.

Dr. Hebert hopes that by 2030, students can take handheld barcoders into the wild and use them to identify plants and animals instantly.

Discussion Questions

1 .
Does the comparison between DNA barcoding and UPC barcodes used in grocery stores help you understand the concept of DNA barcoding? Why or why not?
2 .
How might BIOSCAN’s use of interactions from more than 2,500 sites around the world help the program realize its goals?
3 .
How does Dr. Hebert use the cause-and-effect reasoning strategy in the initiative launched by the team he led? What is the cause of the initiative, and what is its effect?
4 .
How does Dr. Hebert use the reasoning strategy of problem and solution in his proposal about DNA barcoding? What problem does Dr. Hebert address, and what is its solution?
5 .
How would the reasoning strategy of classification and division be useful to a researcher like Dr. Hebert? Support your response with examples from the text.
6 .
In what ways might researchers use a comparison-and contrast reasoning strategy to discover a new species?
