In a lab at Michigan State University, researchers have tracked more than 60,000 generations of E. coli . While most colonies evolved similarly, one famously developed the ability to eat citrate—a "lucky" mutation that others missed, supporting Gould's idea of chance.
On the other side, Conway Morris argues that natural selection is so powerful that it inevitably finds the same "solutions" to environmental problems. If an environment needs a fast swimmer, it will eventually produce something like a shark, a dolphin, or an ichthyosaur—independently. Testing the "Improbable" in the Real World Improbable Destinies: Fate, Chance, and the Fut...
From studying how fruit flies adapt to alcohol to the domestication of Russian silver foxes, Losos illustrates that evolution can happen much faster than Darwin ever imagined—often in just a few generations. Are Humans Inevitable? In a lab at Michigan State University, researchers
While these were once purely philosophical thought experiments, Losos shows that we can now test them using . He takes readers from laboratory flasks to remote islands to meet the scientists "rewinding the tape" in real-time: On the other side, Conway Morris argues that
If you could rewind the history of Earth—every volcanic eruption, every meteor strike, every random mutation—and press "play" again, would the world look the same? Would we still have humans, or would the planet be dominated by bipedal dinosaurs?
Replaying the Tape of Life: A Deep Dive into Jonathan Losos’s Improbable Destinies
If evolution is predictable on Earth, it might be predictable on other planets, giving us a hint of what extraterrestrial life might look like. Final Thoughts
