Do Embryos Show Evolution? Part 2 (CT Scan, Episode 51)

A classic argument for evolution says that different creatures have similar embryos, and therefore share an evolutionary ancestor. 19th-century biologist, Ernst Haeckel, famously forged drawings making embryos appear more alike than they are, and believed embryos re-enact evolution. While most scientists no longer believe this, textbooks still say embryo similarities show evolution in other ways. Let’s continue examining these claims with the 7 Checks of Critical Thinking.
