This guy presents a nice quick history of where evolutionary thought came from, starting well before Darwin.
I thought it was nicely done.

Evolution is the process by which different species of living organisms develop and change over time, typically through natural selection, genetic variation, and adaptation to their environment.
The concept of evolution was first proposed by Charles Darwin in his book "On the Origin of Species" published in 1859. However, the idea of evolution had been discussed by other scientists before him, such as Jean-Baptiste Lamarck and Alfred Russel Wallace.
Natural selection is the process by which certain traits or characteristics become more or less common in a population over time. Organisms with advantageous traits are more likely to survive and reproduce, passing on those traits to their offspring. This leads to changes in the genetic makeup of a population, which can result in evolution.
There is a vast amount of evidence from various fields of study that supports the theory of evolution. This includes fossil records, comparative anatomy, embryology, biogeography, and molecular biology. Additionally, the observation of natural selection in action, such as the development of antibiotic resistance in bacteria, provides further evidence for evolution.
Evolution is both a theory and a fact. The theory of evolution explains the mechanisms by which species change over time, while the fact of evolution is supported by overwhelming evidence from various scientific disciplines. While there may still be gaps in our understanding of certain aspects of evolution, the evidence for it is undeniable.
