David Grimm, an online editor, dives into the curious self-perception of cats, investigating whether they really think of themselves as liquids. Hilarity ensues as he shares anecdotes about their impressive flexibility. Joining him, Ted Schultz, a research entomologist, discusses the incredible history of ant-fungus farming that emerged around 66 million years ago during ecological crises. This fascinating symbiosis reveals how ants adapted to survive by cultivating fungi, offering insights into non-human agricultural practices.
Research indicates that cats possess a limited self-awareness concerning their body size, primarily focusing on height rather than width when navigating spaces.
The evolution of ant-fungus farming illustrates a significant adaptive response to environmental changes, leading to complex agricultural relationships and selective cultivation over millions of years.
Deep dives
Cats and Body Awareness
Research highlights the concept of body size awareness in cats, which reflects how they perceive their physical dimensions. Unlike humans, who have a clear understanding of their body size through visual self-recognition, it remains unclear how cats gauge their own proportions. Experiments reveal that while cats can identify if they fit through narrow openings based on height, they show less concern for their width due to their flexible anatomy. This suggests that cats possess a limited form of self-awareness, only regarding certain dimensions when navigating their environment.
Ants and Fungus Farming
Ants have developed a unique agricultural relationship with certain fungi, relying on fungus gardens for sustenance. This cohabitation began around 66 million years ago, after a catastrophic meteor event created conditions that favored fungal growth. The ants, pre-adapted for farming, began to cultivate fungi as food amid the post-catastrophe scarcity. Research indicates a significant evolutionary shift occurred approximately 27 million years ago, leading to a deeper dependence on cultivated fungi, marking a pivotal moment in their evolution.
Evolutionary Implications of Ant Agriculture
The evolutionary relationship between fungus-farming ants and their cultivated fungi provides insight into broader agricultural practices in the animal kingdom, including those of termites. The study emphasizes the role of environmental changes, such as climate shifts, in fostering these agricultural behaviors. Additionally, by isolating cultivated species from their wild counterparts, similar to human agricultural practices, ants likely enhanced their ability to selectively cultivate advantageous traits. This research opens avenues for understanding how non-human agriculture can evolve and adapt over time.
First up this week, online editor David Grimm joins host Sarah Crespi to talk about how cats think about their own bodies. Do cats think of themselves as a liquid, as much the internet appears to believe? New experiments suggest they may—but only in one dimension.
Next, freelance producer Ariana Remmel is joined by Ted Schultz, a research entomologist at the Smithsonian Institution, to discuss the evolution of ant-fungus farming. It turns out, ants and fungus got together when the earth was going through some really tough times around 66 million years ago.
