What Really Happened to the Other Human Species?

What really happened to the other human species, like Homo erectus, the Denisovans and the 'hobbits' of Flores? You are Homo sapiens, and right now, every single human on Earth belongs to your species. That has never been true before. For millions of years, more than one kind of human walked the planet at the same time, and one by one, they disappeared. This is the story of seven of them, ranked by how long they lasted, and the real reason only one of us is still here. 🔔 Subscribe and hit the bell, so you never miss the next story. 👍 Like the video if it changed how you think about being human. 💬 Comment below: if you could meet one of these seven species face to face, which one would you pick, and why? In this video: Homo erectus, the species that outlasted every other human by far; Homo floresiensis, the "hobbit" found on the island of Flores in 2003; Homo naledi, pulled from a cave so narrow only a small team could reach it; the Neanderthals, closer to us than any textbook let on; the Denisovans, a species discovered from a single finger bone in Siberia; the DNA proof that we interbred with several of them; and the real reason Homo sapiens is the one still standing, tested against every leading theory. If you have ever wondered why you are the only kind of human left, this is the story. ⏱️ CHAPTERS 0:00 Look around you 1:01 Rank 1: Erectus 1:55 Rank 2: Floresiensis 3:03 Rank 3: Naledi 4:22 Rank 4: Neanderthal 6:10 Rank 5: Denisovan 7:32 Rank 6: Kin 8:41 Rank 7: Circle 9:51 Every stranger, every face 📚 SOURCES Natural History Museum, London (homo floresiensis, Neanderthal extinction) · Smithsonian Institution, Human Origins Program · becominghuman.org, timeline of human species · Bradshaw Foundation and John Hawks (Rising Star Cave, Homo naledi) · Nature, Huerta-Sánchez et al. 2014 (Denisovan EPAS1 gene) · Nature, Slon et al. 2018 (Denny, first-generation Neanderthal-Denisovan child) · CNN, 9 September 2026 (new Denisovan fossils, China) · Max Planck Society and Australian Museum (Denisova cave discovery, 2010) · MedlinePlus (NIH), Neanderthal and Denisovan DNA in modern humans · PMC / Berkeley News, timing of interbreeding · The Guardian, Timmermann et al. 2020 climate model on Neanderthal extinction Figures about ongoing research are as of September 2026. ⚠️ This video is history and science education.
