Darwin's ideas and observations about evolution on Earth led to the development of the theory of evolution by natural selection. This theory, proposed in Darwin's famous book "On the Origin of Species," explains how species evolve over time through the process of natural selection, where individuals with advantageous traits are more likely to survive and pass on their genes to the next generation. While the theory of evolution by natural selection is well-supported by evidence and widely accepted in the scientific community, it is technically considered a scientific theory rather than a scientific law.
