Jane Goodall’s Legacy and the End of the Universe: From Termite Fishing to Dark Energy

Overview

This episode honors Jane Goodall by connecting Alejandra Pascual Garrido’s memories of fieldwork at Gombe with ongoing chimpanzee research, highlighting termite fishing, animal personalities, and conservation advocacy. It also features physicist Katie Mack exploring how the universe could end, including heat death and other scenarios, and reports on new findings about how older paternal age raises disease-causing mutations in sperm. The program blends primatology, cosmology, and genetics to illustrate how science spans from forests to the cosmos, rooted in curiosity and humane science.

Introduction and Jane Goodall’s Legacy

The podcast opens with reflections on Jane Goodall’s life and work, emphasizing how her discovery of tool use in chimpanzees reframed human exceptionalism and deepened compassion for animals. Alejandra Pascual Garrido, a primatologist from Oxford and the University of Algarve, shares ten years of field experience at Gombe. She recounts learning from Goodall, the intimate atmosphere of field houses, and how Goodall’s curiosity endured into her late eighties. Garrido explains termite fishing as a focal point of her research, noting that it is taught to offspring and involves sophisticated material selection and planning, revealing chimpanzee cognition and the social transmission of knowledge.

Chimpanzee Cognition and Conservation

The discussion expands to how chimpanzees display personalities, social structures, and cultural behaviors, challenging earlier assumptions of a sharp human-animal divide. The Roots & Shoots program and Jane Goodall Institute offices continue her advocacy, enabling a global network that translates field insight into conservation action. The narrative emphasizes storytelling as a powerful tool for connecting people to nature and inspiring action in everyday life.

End of the Universe and Cosmology

The show shifts to Katie Mack, Hawking Chair of Cosmology at the Perimeter Institute, who explains the prevailing heat death or big freeze scenario alongside alternatives like a big crunch, big rip, and bouncing cosmologies. She discusses dark energy, the cosmological constant, and the possibility that dark energy could be dynamical, which would reopen questions about the universe’s ultimate fate. The conversation also touches on the connection between cosmology and particle physics, noting how current models such as the standard model and lambda-CDM fit data yet leave fundamental mysteries unresolved.
