WebLess-successful types do not pass on as many traits because they have fewer descendants. Over time, failure to reproduce at a rate equal to or greater than the mortality rate leads to extinction. The process whereby the frequency of certain traits within a species change by uneven reproduction rates caused by natural selection is called evolution. WebThis trait is a result of a mutation from thousands of years ago. The mutation causing the trait was beneficial and heritable, so it spread throughout the human population and many of us today have this trait!
