Take a look at a real life example of evolution to teach punctuated equilibrium vs. gradualism. Due to high poaching, several elephant populations are now producing a disproportionate amount of tuskless offspring.
In this product, you'll receive a short, 7 slide PPT to introduce key vocabulary. The two page worksheet asks students a variety of questions based on the National Geographic article listed below. Most importantly, though, students will construct an argument about whether they believe this scenario is an example of punctuated equilibrium or gradualism. Students will also practice using text cited evidence.
