The shadeleaf slingnormous replaced its ancestor, the slingnormous because of its structure. The slignormous was structurally unstable since it had a long, thin stalk and long leaves which usually succumbed to wind resistance. Thus the shadeleaf slingnormous underwent some changes to improve its stability. First, its trunk is wider at the base; and second its leaves grow out from the trunk at a 90 degree angle to reduce wind resistance. The leaves are supported by a strong, hard central "stem" which keeps the leaf from drooping; the leaves themselves shade the ground below and allow water to collect in the soil, helping fauna and flora alike to survive. The sling of its ancestor was also throwing it off balance since it was very large and high up, so it shrunk in its descendant.
