" We are skeptical of claims for the ability of random mutation and natural selection to account for the complexity of life. Careful examination of the evidence for Darwinian theory should be encouraged." - Dissent from Darwin

Natural selection [is used] carelessly as a mantra, as in the evidence-free “just-so stories” concocted out of thin air by mentally lazy adaptationists. (Stephen Jay Gould)

In the absence of any other proof, the thumb alone would convince me of God's existence. (Isaac newton)

According to Jon Mitchell from the University of Chicago, "A SET of 200-million-year-old teeth from a beast related to dinosaurs and crocodiles has shed light on how snake fangs evolved. They support the idea that venom canals inside fangs evolved from grooves on the tooth surface."  Jon and his colleagues discovered 26 Uatchitodon teeth that  shows how grooves initially formed at the surface and gradually lengthened and deepened until they became enclosed canals. Bryan Grieg Fry from the University of Melbourne, Australia, is convinced this is the case, and says the fossil series is "fantastic".
