Evolutionists believe that the embryos of different mammals look similar in the earliest stages of development because the mammals share a common ancestor. And they believe that as the embryos develop, they begin to look less similar. This theory was invented by Ernst Haeckel, who believed that”ontogeny recapitulates phylogeny”.
With that mind, consider this post by embryologist Jonathan Wells at Evolution News, in which he describes PBS’s latest effort to use taxpayer dollars to push evolution on children, without any presentation of opposing views.
On the website for its December 29 special, PBS offers an interactive “Guess the Embryo” exercise featuring four different vertebrate embryos: an 8 day-old mouse, a 5 day-old quail, a 17 day-old turtle, and a 40 day-old bat. The purpose of the exercise is to convince viewers that “embryos of different species can appear startlingly similar to one another.” A discerning viewer, however, will notice that the turtle embryo already has a rudimentary shell on its back—thus distinguishing it clearly from the others. A discerning viewer might also notice that the bat embryo bears little resemblance to the mouse embryo, even though both are mammals. What viewers may not know—and PBS does not tell them—is that the interactive exercise shows embryos midway through development. The earliest stages are systematically omitted. Perhaps this is because in their earliest stages vertebrate embryos are striking different from each other. They follow a pattern that embryologists call the “developmental hourglass”—wide at the top, narrow in the middle, and wide at the bottom. In other words, vertebrate embryos start out very different from each other, become superficially similar midway through development, then diverge again as they mature. Like Darwin’s German disciple Ernst Haeckel, PBS distorts vertebrate development to make it seem to provide evidence for Darwin’s theory.
As Wells notes, the embryological evidence actually shows that mammal embryos are different in the earliest stages, and similar in the middle stages of development. So embryological development Darwinian fundamentalist Ernst Haeckel’s embryo drawings were discredited as a fraud in the 19th century. The drawings also showed intermediate stages of embryo development – not the earliest stages.
Wells’ Ph.D in Biology is from the University of California at Berkeley. His area of specialization is embryology, in which he has conducted post-doctoral research.
