Quick takeaways
The decline of species highlights the need for accurate data collection and avoiding oversimplification or dismissal of environmental issues based on flawed models or biases.
The case of the extinct woolly dogs in the Pacific Northwest highlights the importance of combining Western science with indigenous oral traditions to uncover the truth and preserve cultural practices.
Deep dives
The Mystery of the Disappearing Gulls and the Increasing Conch
During a recent trip to the Bahamas, the podcast hosts noticed a significant decrease in the number of gulls compared to previous visits. The absence of gulls, along with an increase in conch population, raised questions about the state of the environment. Theories such as seasonal migration, a pathogen, or a local patchiness were considered as possible explanations. The decline in gull numbers mirrored the familiar pattern of species decline seen around the world. The hosts highlighted the need for accurate data collection to better understand population trends and emphasized the complexity of environmental issues, which should not be oversimplified or dismissed based on flawed models or political biases.
The decline of species and the importance of paying attention
The podcast episode discusses the decline of species and emphasizes the importance of paying attention to the changes happening in the natural world. The speaker highlights that anecdotal evidence can be misleading and urges caution in drawing conclusions. They mention the risk factors for decline, including migration, pathogens, local patchiness, and massive meaningful decline. Furthermore, they emphasize that once a population reaches zero, there is no recovery, highlighting the need to take action and prevent such declines.
The significance of woolly dogs in the Pacific Northwest
The podcast episode also explores the case of the extinct woolly dogs in the Pacific Northwest. The speaker emphasizes the importance of combining Western science and indigenous oral traditions to uncover the truth. They discuss the research that discovered the existence of these dogs through DNA analysis and the oral traditions of the Coast Salish people. The woolly dogs were bred for their remarkable coats, which were ideal for making warm and long-lasting blankets. However, the introduction of diseases, colonization, and cultural upheaval contributed to the decline and eventual extinction of these dogs. This example highlights the importance of preserving cultural practices and traditions while also acknowledging the contributions of Western science.
In this 205th in a series of live discussions with Bret Weinstein and Heather Heying (both PhDs in Biology), we discuss the state of the world through an evolutionary lens.
In this episode, we briefly discuss solar storms, Carrington events, and the possible failure of the electrical grid. Then: what does the absence of organisms where they once were mean? In the Exumas, Bahamas, this month, there were no laughing gulls. Eight months ago they were abundant in the same place. Could they be migrating? Might it be a pathogen? Local patchiness? Major decline for other reasons, like competition, or toxicity from plastics or pesticides? We discuss conservation success stories, like sea otters and bald eagles and California condors; and failures, like sea stars on the West coast of North America; and show some videos from the Bahamas. We object to the conflation of “environmental decline” with “climate change.” And we discuss curly haired “woolly dogs” of the Pacific Northwest, who were bred and cared for by the Coast Salish people, but are now extinct.
