Likewise with their attack on the phrase “survival of the fittest.” This is not how evolutionary scientists generally describe evolution, and the term was actually coined not by Charles Darwin, but by Herbert Spencer who was writing about his ideas of economics and likening them to Darwin’s Natural Selection.
“Fittest” in this manner is a misnomer because what’s considered ‘fit’ in one environment may prove to be a serious disadvantage in another.
In a given environment, species with certain traits will have certain advantages over others and therefore have much higher likelihood to survive and reproduce, thereby passing on the genetic traits that made them successful, while those without these traits will be less likely to survive and reproduce and therefore those traits that proved to be disadvantageous will be less likely to continually exist in a species. Sometimes species will spread out become isolated from each other, and the same species will exist in completely different environments. This will result in a different set of traits to be naturally selected (in real time, these small changes are known as micro evolution) and over millions of years, will result in gradual large-scale changes (macro evolution).
Evolution explain how life as we know it came to be, and this was accomplished via genetic changes (the successive change in alleles) that occur each reproductive cycle (we know this happens, because none of us are identical to our parents nor our siblings.
