Jon Hamilton, an NPR science correspondent, hosts a captivating discussion with neuroscientist Erich Jarvis, chair of the Vertebrate Genomes Project. They explore the ambitious goal of sequencing 70,000 animal genomes to boost conservation efforts and understand evolution. The fascinating role of the platypus shines as a key player in unraveling mammalian traits. They also delve into the links between vocal learning and cognition in animals, pondering the ethical implications of genetic engineering related to vocalization.
The Vertebrate Genomes Project aims to sequence 70,000 species' genomes to uncover evolutionary traits and aid in biodiversity conservation.
Insights from the genomic data could revolutionize our understanding of vocal learning and challenge traditional notions of intelligence in animals.

Understanding Human Uniqueness Through Genomics
The sequencing of genomes is crucial for uncovering what makes humans distinct from other species. Scientists aim to gather genomic data from approximately 70,000 species, starting with about 260, including various birds, mammals, and reptiles. By analyzing these genomes, researchers can identify the specific genetic factors that define different lineages, answering fundamental questions about evolution. This comprehensive database will not only enhance our understanding of genetics but also help preserve species that are at risk of extinction.
The Intersection of Vocal Learning and Genetics
Understanding vocal learning—a rare ability shared by humans, some birds, dolphins, and other animals—requires insights from genetics and brain function. Research shows that species showcasing advanced vocal imitation also exhibit higher problem-solving skills, suggesting a connection between vocal learning and cognitive complexity. The collection of genomic data will allow scientists to explore the genes associated with vocal capabilities in different species, enhancing our grasp of how vocal communication evolved. This could lead to breakthroughs in understanding vocal communication circuits and their potential applications in fields like genetic engineering.
Revisiting Human Complexity and Behavioral Intelligence
The conversation around what constitutes intelligent behavior is evolving, with examples of complex actions in the animal kingdom challenging traditional views. Species such as bowerbirds illustrate that advanced behaviors are not exclusive to humans, as they build intricate structures for mate attraction. This raises important questions about how we classify intelligence and complex behavior across species. As genomic data advances, it may shift our perceptions of human uniqueness, revealing shared traits and behaviors with other intelligent animals.
The Vertebrate Genomes Project: It's an ambitious effort by an international group of scientists to create a "Genome Ark" by sequencing the genomes of about 70,000 animal species. The hope is that through all of this gene sequencing, scientists will be able to answer some basic but important questions like: What makes a bird, well, a bird? What makes a mammal a mammal? Plus, with so many species on the verge of extinction, can scientists record their genetic information before they go extinct – or better yet, maybe help save the population from going extinct? Guest host Jon Hamilton, one of our favorite science correspondents, talks to Erich Jarvis, the chair of this project, to learn what this ark of animal genomes could mean for our future – and why a platypus qualified for early boarding.
