so much information. My math skills are being challenged
I Really liked the video that used the five fingers on our hands that explain microevolution. The animation was cool and it was easy to remember.
I really enjoyed learning about speciation
What I liked about this lesson the most was Hardy-Weinberg laws and knowing how to know when a population is evolving over time.
it was interesting to learn there has been more than 20 mass extinction
