Evolution & How it Works
... I = Inheritance: Genetic traits are inherited from parents and passed on to offspring. S = Selection: Organisms with traits that are favorable for survival get to live and pass on their genes to the next generation. T = Time: Evolution can happen in a few generations, but major change, such as speci ...
