#1086 John Odling-Smee - Niche Construction: How Life Contributes to Its Own Evolution
Apr 18, 2025
John Odling-Smee, Emeritus Research Fellow at Oxford and author of 'Niche Construction', dives into how life shapes its own evolution. He discusses the pivotal role of niche construction in ecology, highlighting how organisms like birds and their behaviors mold their environments. The conversation challenges traditional evolutionary views, incorporating concepts like adaptive know-how and even cultural evolution's impact on genetics. From thermodynamics to ecosystem dynamics, Odling-Smee offers a fresh perspective on the interconnectedness of life and its surroundings.

- Niche construction illustrates how organisms modify their ecosystems, influencing natural selection and highlighting the reciprocal relationship between life and environment.
Deep dives
The Second Law of Thermodynamics and Life
The second law of thermodynamics, which states that entropy or disorder increases over time, plays a crucial role in understanding life and its origins. Living organisms must actively resist this law to achieve their survival and reproduction goals, acting purposefully in their environments. Unlike inanimate systems that simply obey this law, life represents complex, goal-seeking systems that must manage their internal and external dynamics to thrive. The discussion emphasizes that any definition of life should start from its need to counteract entropy rather than merely focusing on survival and reproduction.
