Species Change over Time Because of Natural Selection

  • Individuals with traits better suited to their environment (adaptations), survive better than those with lesser traits

  • Better genes get passed on leading to species changing - for the better.

  • Living things have been on earth for billions of years.  Evolution has produced many different species along the way.

  • We can see clues to how closely species are related to each other
