1831 publication

The 1831 publication, most notably "On the Origin of Species" by Charles Darwin, introduced the theory of evolution by natural selection. Darwin proposed that species change over time through a process where individuals with advantageous traits are more likely to survive and reproduce. This idea challenged existing beliefs about fixed, unchanging species, providing a scientific explanation for the diversity of life seen on Earth. The publication revolutionized biology, influencing how we understand natural history and our own place in the natural world.
