With all the incredible diversity of life, it’s fascinating how often evolution repeats itself. The fossil record and the modern world are full of signs of this pattern of convergent evolution – similar pressures drive organisms to similar features and lifestyles. In this episode, we’ll talk about what exactly convergent evolution entails, share some of our favorite examples, and talk about how things can get a bit confusing.
Did we mention your favorite example of convergent evolution?
In the news: rhino DNA, baby sea turtles, sea snake breathing, and dinosaur temperatures.
