Evolution is not just a theory - Every new breakthrough discredits creationism or intelligent design, so why does it persist. ? Because too many people don't read

Some of the latest research on evolution focuses on chicken embryos. Apparently evolution works by adding genes rather than replacing them, so in the early embryonic stages it is often possible to glimpse what an organism's ancestors may have looked like. The early embryos of many mammals often look remarkably similar. Specifically in the case of chickens, the embryo forms five main claws ( like it's raptor ancestors )in it's early stages, then later these disappear to give way to three main claws. The cumulative evidence is beginning to be so overwhelming, how can anyone doubt that evolution is a fact , not just a theory ? How can such irrationalism persist in the modern age ? Maybe too many people just don't like reading.
