That is one of the biggest misconceptions about evolution. Parent species don't have to disappear just because they give off other species...
I don't believe in (MACRO)evolution either.
Then where are the half-ape half-humans? Where are the current evolving species? Where are the proto-humans and super-humans? A few million years is NOT window enough for vast, out and out interspecies evolution across the globe. Sorry, it's bunk. And before anyone presumes, this is not coming from a "fundamentalist."
Look at the numerous "missing links" - most discredited, the rest tenuous at best.
Yes, they do have to dissapear, if they don't then they didn't evolve.The biggest misconcepion about evolution is that there are missing links of any kind. There are no transitional species and everytime they claim they have found one, it turns out to be something else. The horse line that used to be found in books, is all fake, among other things, has been proven to be so and the little creature that is supposed to be the earliest horse isn't really a horse and never "evolved into one". Evolution will be one of the greatest stains on science some day, when the people trying to perpetuate this myth finally come to their senses and start once again to be scientific. If you doubt my word read about the Cambrian explosion and answer the questons posed by that phenomonon, questions no evolutionists has been able to answer, and you will solve some riddles. Thanks...
