Which individual is known for creating the Theory of Evolution?

The Theory of Evolution is primarily associated with Charles Darwin due to his groundbreaking work in the 19th century. Darwin proposed that species evolve over time through a process called natural selection, where individuals with favorable traits are more likely to survive and reproduce. His observations, particularly during his voyage on the HMS Beagle, led him to understand how variations within species impact their survival and adaptability to changing environments.

Darwin's seminal work, "On the Origin of Species," published in 1859, laid the foundation for the field of evolutionary biology. Through detailed observations and an extensive collection of evidence, he demonstrated how diverse biological life could be traced back to common ancestors, fundamentally changing our understanding of biology and the interconnectedness of life on Earth.

The other individuals listed have made significant contributions to science, but their work does not pertain to the Theory of Evolution. Claude Bernard is known for his work in physiology, particularly the concept of homeostasis. Louis Pasteur is most celebrated for his advancements in microbiology and immunology, particularly the principles of vaccination and pasteurization. Peter Singer is a philosopher known for his work in ethics and animal rights but not for contributions to evolutionary theory.
