Ravens are originally from the genus Corvus and have a widespread presence mainly across the Northern Hemisphere. The common raven (Corvus corax) is found across much of this hemisphere and is one of the largest and most well- known raven species. Ravens evolved over millions of years and their ancestors can be traced back through a complex evolutionary history that includes links to ancient birds and ultimately dinosaurs, as birds descended from theropod dinosaurs like Archaeopteryx. Native American legend, particularly from Pacific Northwest tribes, includes mythological stories about the Raven being a primordial figure present from the beginning of time. Here are key points about the origin and nature of ravens:
- Ravens belong to the genus Corvus and are closely related to crows, with distinctions mainly based on size.
- They have existed for millions of years, with fossil evidence showing ravens in early human encampments in North America around 10,000 years ago.
- The common raven is a species native to the Northern Hemisphere.
- Evolutionarily, ravens are descended from ancient birds that themselves evolved from dinosaurs.
- Ravens hold cultural significance in many indigenous cultures, especially in the Pacific Northwest, where legends recount the Raven as a creator and bringer of light.
- The term "raven" has roots in old Germanic languages, reflecting the black bird's presence in Northern Europe for centuries.
Thus, ravens are originally from the Northern Hemisphere with a history intertwined with both evolutionary biology as ancient birds and rich cultural mythology across various human societies.
