Lesson 70 of 84 ยท Evolution
Experimentโญ 30 XPChromosomes: Packages of DNA (Part 4)
Evolution.
๐ฏ Your mission
Predict it first. Then prove yourself right (or wrong).
โก The twist
Nature loves to surprise the careful watcher.
Mind = Blown
๐ฌ The more you look, the more nature shows you.
Make a hypothesis first
Before you start: write down what you think will happen, and why.
