Jacob Burckhardt's interpretation of the renaissance was a prototype of the modern world. Scholars think he overlooked the continuity between the middle ages and the renaissance.

Kelp forests are underwater areas with a high density of kelp. They are recognized as one of the most productive and dynamic ecosystems on Earth. Smaller areas of anchored kelp are called kelp beds.
