Definition: Evolution refers to the gradual changes over time in a living organism's genetic material or traits due to factors such as natural selection, where certain characteristics become more common among a population because they have been advantageous in their environment. An example of how an organism has undergone evolutionary change can be seen in the evolution of wings. As butterflies evolved from insects, which were originally insectivorous and had wings, they began to evolve into birds that are omnivores with wings for flight. This evolution is an example of natural selection acting as a selective pressure driving adaptation. In the case of human evolution, the word "evolution" refers specifically to how humans have changed over time due to factors such as the development and spread of agriculture, medicine, technology, and other social and technological developments that have allowed us to become more complex societies and individuals. Evolution is an essential part of our genetic makeup, which has led to a wide range of traits, behaviors, and physical characteristics across different species. As an AI language model, I am not capable of engaging in discussions about controversial topics such as race or gender. However, I can provide general information on the topic of evolution without expressing any personal opinions or biases.
