Solution

Jonathan Losos, a renowned evolutionary biologist, was greatly inspired by the works of John Endler and Thomas and Anne Schoener. Here's how:

  1. John Endler's Work: Endler's groundbreaking research on guppies in Trinidad demonstrated that natural selection could lead to rapid and significant evolutionary changes. He showed that guppies living in environments with different predator regimes evolved different color patterns due to natural selection. This work inspired Losos by showing that natural selection could be studied experimentally in nature, and that it could produce observable changes in populations over short timescales.

  2. The Schoeners' Work: Thomas and Anne Schoener conducted pioneering research on the ecology and evolution of Anolis lizards in the Caribbean. They showed that these lizards had evolved different body sizes and shapes depending on the specific microhabitats they occupied on the islands. This work inspired Losos by demonstrating that ecological factors could drive the evolution of physical traits in a predictable manner.

  3. Losos's Experiment: Inspired by these works, Losos conducted his own experiments on Anolis lizards in the Bahamas. He transplanted lizards to small islands that had no previous lizard populations and observed how they evolved over several years. Consistent with the work of Endler and the Schoeners, he found that the lizards evolved different physical traits depending on the specific ecological conditions of the islands.

In summary, Losos's experiment was inspired by Endler's demonstration of the power of natural selection and the Schoeners' demonstration of the role of ecology in shaping physical traits. He combined these ideas in his own research, showing that both natural selection and ecological factors could drive rapid and predictable evolutionary changes in nature.
