Kale Cauliflower and Brussels Sprouts Are the Same Species

The video explores the diversity of Brassica oleracea, a plant species with varieties like kale, broccoli, and cabbage, likened to the diversity seen in dog breeds. This diversity is due to significant genomic events in its evolution, leading to a wide range of cultivars. The plant's domestication history and genetic variation are discussed, highlighting its adaptability and the challenges in tracing its evolutionary timeline. Understanding these variations can aid in developing more resilient and nutritious crops.
