Why are very similar trees all over the world? Why are there there pine trees in Europe but also in the USA?
Did tree species evolve independently across the world? Did trees spread before contigents spread apart? Did some dinosaur bird migrate with a twig in their beak??
In: Biology
Trees evolved somewhere around 420-350 million years ago, and Pangaea didn’t break up until around 200 million years ago. They had plenty of time to spread across the land in between.
