Evolution's evidence gets laid out in one sitting: comparative anatomy, the fossil record, genetics, and biogeography, stacked together to make the case for common descent and macroevolution. The film moves through transitional fossils, including a sequence of hominid skulls tracing changes in skull shape and brain case over time, and pairs that with molecular evidence, DNA comparisons across species that point to shared ancestry. It is built as a survey rather than a narrative, working through one line of evidence after another rather than following a single research story or scientist. A companion film, Mechanisms of Evolution, follows this one and covers the processes, natural selection, mutation, genetic drift, that the evidence here is used to support. Produced by the Cassiopeia Project, an outfit that makes free science education videos, the film keeps its focus narrow: not why evolution happens, but what the physical and genetic record actually shows.
