Neanderthals, once dismissed as primitive brutes, have been at the center of numerous groundbreaking studies in 2025, reshaping our understanding of their lives and their connections to modern humans. Recent research suggests that Neanderthals were not only skilled hunters and artists but also shared intimate social behaviors, such as kissing, with Homo sapiens. A digitally reconstructed skull from Israel points to early and extensive interbreeding between the two groups, challenging the idea that Neanderthals were a separate, inferior species. Archaeological finds, including a 42,000-year-old ocher crayon and evidence of diverse diets, further highlight Neanderthal sophistication and adaptability. Ongoing debates among scientists focus on whether Neanderthals and Homo sapiens should be considered one species or two, but new discoveries continue to reveal a complex and intertwined evolutionary history.
