The Edge of Evolutionary Biology

"The Edge of Evolutionary Biology" refers to the limits of evolutionary change that can be observed in nature. It discusses how evolution works through mechanisms like natural selection and genetic mutation, but highlights that not all traits or behaviors can evolve easily. Some complex features may require specific conditions and long time frames, making them rare. The book emphasizes that while evolution is a powerful process, it has boundaries shaped by genetic and environmental factors, which can lead to misunderstandings about the flexibility and adaptability of life forms.
