## [Natural Selection In this unit, students figure out the interconnectedness of genetics, heredity, and evolution. For this lesson, students create an experiment to observe the phenomenon of natural selection determining which organisms are most likely to survive and pass on their traits. This page showcases parts of key components of the lesson.](https://www.knowatom.com/science-phenomena-videos/8th-grade-science/natural-selection)
