Suppose a scientist discovers fossils of ancient horses in an area. The fossilized horses are much smaller than modern horses. They are found in the same layer as many fossilized tree trunks. Today, horses still live in the area, but it is now open grassland.

How do you think the environment has changed over time, and how could this change have led modern horses to be larger than ancient horses?

Not the answer but think about this, the question tells you that the fossil was found in the same level as tree trunks which means it was a tight forest. in the picture there were fish with the fossil and the trunks were broken therefore, a water force could be a reason why the forest became a grassland. As for the horse size transformation, with a tight forest horses today would be wayy too big to get through a tight forest 24/7. The horses need to be small to live in the forest so when the forest was ruined they didn't have to fit through a forest. When the forest became a grassland horses could start running and exercise. When you exercise do you build muscle and bones? Yes, that means they grew. A great comparison is the turtles you get at the beach. The bigger the tank the bigger they become, right?
