Natural selection is the driving force of evolution. It is the selective breeding that results from the obstacles to reproduction that are imposed by the natural environment. Evolution can occur slowly, fast, or not at all depending on the rate and type of environmental change and athe amount of variation that exists among members of a species. An individual or species that changes in response to the demands of its environment is adapting to these new demands. Genetic makeup of moths now specify black color.
Humans use words to pass on what has been learned.
NEW ideas and objects gradually replace those that are older and less useful. Proceeds much more quickly than biological evolution. 15 years ago I didn't consider bringing a computer. I arrived at college with my typewriter and pocket calculator. One object has effectively replaced another object.
