Penguin Evolution and Fossil Discoveries

The video explores the discovery of penguin fossils in Peru, which have reshaped our understanding of penguin evolution. These fossils, found in 2006, revealed unique features such as scale impressions and soft tissue evidence. The findings also provided insights into early feather modifications, showing a streamlined contour and dense packing of primary feathers. Additionally, the video discusses the preservation of color in fossil feathers, revealing that ancient penguins had a different appearance compared to modern ones. This research highlights the rich evolutionary history of penguins.
