Togetherness - Symbiosis and the hidden story of life’s hidden collaborations
The Science Show - Separate stories podcastSummary
Rowan Hooper, a writer for New Scientist and author of the newly released book "Togetherness," explores the intricate relationships that define life on Earth. The book delves into the concept of symbiosis, highlighting how various organisms, from trees to microorganisms, collaborate in complex ecosystems. Hooper emphasizes that a single oak tree can host around 200 different species, creating tiny ecosystems that interact in remarkable ways, showcasing the interconnectedness of life.
Hooper discusses the historical significance of symbiosis, referencing Lynn Margulis, who contributed to the Gaia theory. He explains how ancient bacteria became mitochondria within cells, enabling the evolution of complex life forms. This process of symbiosis is not limited to animals; it also extends to plants, where cyanobacteria evolved into chloroplasts, leading to the development of plant life. The conversation touches on the importance of recognizing cooperation in nature, which has often been overshadowed by the competitive narratives prevalent in evolutionary biology.
The discussion also highlights the extensive fungal networks that connect plants, facilitating nutrient exchange and water supply. Hooper points out that these networks, sometimes referred to as the "Wood Wide Web," are crucial for ecosystem health. He argues that while competition exists in nature, the role of cooperation and symbiosis is equally vital and often overlooked. By bringing together various fields of biology, Hooper aims to foster a deeper understanding of the pervasive nature of symbiosis across all life forms.
Show Notes
No more “Red In Tooth and Claw”? Well, that’s not the only story in evolution – from the beginning. Rowan Hooper in his latest book, Togetherness, shows how lichens, corals and even ourselves, flourish by means of other life forms. We have mitochondria, plants have chloroplasts, both formerly free-living creatures. We would not have evolved to our current form and could not survive without these once-invaders.

Bees survive by collaboration. To fight infection, bees arrange their honey and other stores in ways that repel disease. Microbiologist and bee researcher Kenya Fernandes led a study into the ways bees arrange their hives for maximum protection from microbial infection.
Lions are under considerable stress across Africa. Their habitat is fragmented and impacted by human activity such as agriculture. Being unable to roam freely, has led to inbreeding. Climate change is expected to impact their habitat and bring additional stress.
Why did reptiles prevail for so long and why did mammals take so long to become dominant predators? Adam Lindholm is looking at body size, availability of prey and environmental conditions to reconsider our understanding of the history of reptiles and mammals.
Theme parks and museums draw big crowds for dinosaurs. Kids love them. But palaeontologist James Ronan says some displays are based on ideas from the 1970s and present sound effects from movies. He says it is important to present current ideas about palaeontology accurately. So James Ronan is undertaking a worldwide audit of dinosaurs. Science communicator and podcast host Conor O’Keefe is also disturbed by inaccurate dinosaur displays at theme parks and supports the dinosaur edit saying it is long overdue.
Over the past few years, our environment seems to have experienced multiple extreme events in quick succession. With a summer fuelled by what may be the strongest and wettest El Niño ever, can our wildlife withstand more extremes? Jonathan Webb speaks with Professor Euan Ritchie about what we're currently seeing with flying foxes, what could happen to other species over the summer, and what we can do to help our native creatures.
