Charles Darwin introduced the concept of biological evolution through natural selection in his book "On the Origin of Species" published in 1859. Darwin proposed that species evolve over successive generations through the process of natural selection acting on variations within populations.

I don't know about Wallace, but Darwin spent a lot of his time in the Galapagos Islands where he saw what he thought was natural selection in action without interference from, or as a response to, outside sources like mankind.
The Galapagos Islands influenced Charles Darwin's theory of evolution by providing him with diverse and unique species that showed variations in traits, leading him to develop the concept of natural selection as a mechanism for evolution.
The concept of evolution existed before the theory of natural selection. Evolution as a concept dates back to ancient Greek philosophers, while natural selection was proposed by Charles Darwin in the 19th century as a mechanism to explain how evolution occurs.
Charles Darwin emphasized the concept of natural selection as the mechanism for evolution. He proposed that species evolve over time through the process of natural selection, where individuals with advantageous traits are more likely to survive and reproduce, passing on those traits to future generations.
Charles Darwin did not coin the concept of evolution, but he is famously known for developing the theory of evolution by natural selection. Evolution as a concept had been discussed by earlier scientists and philosophers before Darwin. Darwin's contribution was to provide a comprehensive explanation for how evolution occurs through the mechanism of natural selection.

Natural selection was formally accepted as a major mechanism of evolution in the 19th century with the publication of Charles Darwin's seminal work "On the Origin of Species" in 1859. However, the concept of natural selection was not widely accepted until later in the 20th century when more evidence in support of the theory accumulated.
Without genetic diversity, natural selection cannot occur
