Variation, Even in Twins!
This week in class, we learned about evolution. Prior to class, I wasn't aware that evolution was NOT possible within a lifetime, nor that humans didn't directly evolve from monkeys. I feel like everything I've learned has been a lie before today! Today in class, Dr. Boswell mentioned that there wasn't a single person in the room who was exactly the same. Kerri, my twin, and I looked at each other and smiled. Even with identical DNA, it's true that we are different, due to environmental factors and epigenetic changes. Tying it all back to what we learned about evolution - variation is necessary for natural selection. We recently played a Kahoot in class about evolution and the importance of natural selection. Even minor differences can play a role in a population over a long enough period of time. Variation is everywhere, even within me and my twin!
