In his Oct. 30 letter, \"For some, evolution is still a theory,\" Frank Langford argued that evolution has not yet been proven; it's still a theory.<\/p>\n
Langford might be surprised to learn that every competent scientist would agree with him. Of course evolution is a theory. So is gravity.<\/p>\n
Langford is confusing the scientific terms \"hypothesis\" (an unproven guess) and \"theory\" (an explanation that can be used to make predictions).<\/p>\n
Gravity is a theory, meaning that scientists can use their knowledge of gravity to make predictions. For example, scientists used the theory of gravity to declare that black holes long existed - before they had the technology to find those black holes in space.<\/p>\n
Similarly scientists have long used the theory of evolution to predict natural phenomena that haven't been discovered yet.<\/p>\n
