Over the past year and a half, The Brain Scoop has taken viewers on a fascinating journey into the world of animal anatomy. From examining a squirrel to dissecting a wolf, these activities might seem unusual at first glance. However, they serve a crucial scientific purpose that extends beyond mere exploration of animal biology. The specimens we work with are prepared for museum collections, which help us understand how species change over time. For instance, the wolf we studied will be housed at The University of Montana, and the data from its radio collar will be invaluable for biologists and wildlife managers.
These efforts are part of a larger mission by biologists to comprehend biodiversity and ecosystems. Although the wolf’s death was not natural, it allowed us to gather important information that might have otherwise been lost. Recently, a debate has emerged following an opinion piece in Science magazine by scientists from Arizona State University. They suggested that collecting specimens in the field might contribute to species extinctions, sparking a discussion about the role of biological collecting.
While salvaged roadkill and birds that collide with windows contribute significantly to museum collections, relying solely on these sources does not provide a complete picture. The controversy centers on the suggestion that field biologists should stop collecting voucher specimens and instead focus on tissue sampling and photo documentation. This opinion was met with a response from over 100 biologists from leading research institutions and museums worldwide who respectfully disagreed.
Museum specimens are like library books filled with information that can be referenced repeatedly. For example, a bat collected in the early 1900s can offer insights into its species’ distribution and changes over time. By studying these specimens, scientists can gather genetic information that helps us understand historical climate conditions. Continuous monitoring of populations can alert us to potential threats from diseases, human impact, or invasive species.
Voucher specimens are crucial in understanding and mitigating the effects of epidemics, such as the white-nose syndrome affecting bats. Collecting live bats for study can yield knowledge that helps prevent the extinction of entire populations. This research can also inform health professionals about the spread of infectious diseases, which can significantly impact human health.
Historical examples, like the use of museum egg collections in the 1960s to study the effects of DDT on bird populations, highlight the importance of ongoing specimen collection. Researchers identified the decline of bird species due to thinning eggshells caused by DDT, which could have led to further environmental issues had biologists not been collecting data since the 1880s.
It’s important to note that biologists do not collect specimens indiscriminately. The collection process is guided by previous research and is regulated by permits. Biologists follow strict ethical guidelines similar to those in the medical field, ensuring that their actions prioritize the health and safety of ecosystems.
If we overlook the importance of these collections, we risk losing valuable resources for understanding and preserving species, including our own. The Brain Scoop is brought to you by The Field Museum in Chicago, highlighting the vital role of museums in scientific research and education.
Engage in a virtual dissection of various animals to understand their anatomy. Use online tools to explore different species and compare their anatomical structures. Reflect on how these structures relate to their ecological roles and adaptations.
Participate in a debate about the ethical implications of collecting voucher specimens versus alternative methods like tissue sampling and photo documentation. Research both sides of the argument and present your findings to the class.
Visit a local museum or explore an online museum database to analyze the diversity of specimens collected. Discuss how these collections contribute to our understanding of biodiversity and the historical changes in species distribution.
Conduct a case study on a specific epidemic or environmental threat, such as white-nose syndrome in bats. Investigate how voucher specimens have been used to understand and address these issues, and propose potential solutions based on your findings.
Participate in a workshop to develop ethical guidelines for specimen collection. Collaborate with peers to create a set of principles that balance scientific research with conservation efforts, and present your guidelines to the class.

Over the last year and a half on The Brain Scoop, you’ve all watched as I’ve engaged in various activities related to animal anatomy. This has included examining a squirrel, studying an anteater, analyzing a two-faced calf, and dissecting a wolf. While these activities may seem unusual, they serve an important scientific purpose beyond just the exploration of animal biology. The specimens we work with are prepared for museums, contributing to our understanding of species changes over time. For instance, the wolf will be housed at The University of Montana, and the data collected from its radio collar will be a valuable resource for biologists and wildlife managers.
This is just one part of a larger effort by biologists to understand biodiversity and ecosystems. The wolf’s death, while not natural, allowed us to salvage valuable information that would otherwise have been lost. Recently, a few scientists from Arizona State University published an opinion piece in Science magazine suggesting that collecting specimens in the field contributes to species extinctions. This has sparked a debate about the role of biological collecting, which we haven’t explicitly addressed on The Brain Scoop.
It is true that salvaged roadkill and birds that collide with windows contribute significantly to museum collections. However, relying solely on these sources does not provide a complete picture. The controversy arises from the recommendation that field biologists should stop collecting voucher specimens and instead focus on tissue sampling and photo documentation. This opinion was met with a response from over 100 biologists from top research institutions and museums worldwide who respectfully disagree.

Anatomy – The branch of science concerned with the bodily structure of humans, animals, and other living organisms, especially as revealed by dissection and the separation of parts. – Understanding the anatomy of different species is crucial for comparative biology studies.
Biodiversity – The variety of plant and animal life in a particular habitat, often considered a measure of the health of an ecosystem. – Conservation efforts are essential to maintain the biodiversity of the Amazon rainforest.
Ecosystems – A biological community of interacting organisms and their physical environment. – Climate change poses a significant threat to marine ecosystems worldwide.
Specimens – Individual animals, plants, or minerals used as an example of their species or type for scientific study or display. – The museum’s collection includes specimens from various extinct species.
