If any insect that existed 50 million years ago had all the organs and physical features possessed by the same insect today, then it is impossible to state that this life form has achieved its present form through evolution. Research over the last 150 years or so has produced no candidates for the supposed ancestor of the more than 1 million known species of insects. Nor is it likely for any answer to be forthcoming in the future, because insects are not descended from any alleged common forebear. Insects did not assume their present-day forms through evolution. Every species is created with its own particular characteristics and never changes so long as that species survives. The fossil record is the most important proof of that.
