Hi there! I visited the Brooklyn Aquarium last summer. One of the animals that impressed me the most was the horseshoe crab. They have been in this planet for more than 450 million of years without changes in their body shape. They closely related to the family of scorpions and spiders. And you can see in the picture that under the shell it really looks like a spider! That makes me think that maybe horseshoe crabs were spiders before being horseshoes. Or that some horseshoe crabs became spiders. It very interesting for me how some organism have change along million of years. Did you know that dolphins before being dolphins were an animal that looked like a dog?
Are you sure you weren't a biologist? You raise some interesting evolutionary issues. I had no idea about the dolphin ancestors. How strange?
