Communicate scientific information that common ancestry and biological evolution are supported by multiple lines of empirical evidence.

  1. Fossils

    Baby titanosaur was a mini version of its parents

    Fossils show that baby titanosaurs looked like mom and dad. They may have been active and independent from a young age.

    Neandertal toe contains human DNA

    DNA from a 50,000-year-old Neandertal woman’s toe bone shows humans left a mark on the ancient species — and much earlier than scientists had thought.
