SciShow: Abilities Evolution Took From Us

Teacher or professor: SciShow
Subject: Science
Content of the Lesson: A common misconception is that evolution is a long chain of progress, where organisms gain cool, new features over time. However, if a trait doesn't help with survival or reproduction, eventually it can disappear. Here are a few abilities humans' distant ancestors had that have been lost to natural selection!
