Overview
The concept of species has been debated by biologists, taxonomists, and philosophers for centuries, with over 8.7 million identified species on Earth, according to a 2019 study published in the journal PLOS Biology. The historian sees species as a product of evolutionary history, with the first species classifications dating back to Aristotle in 350 BCE. However, the skeptic questions the validity of species as a fixed concept, citing the existence of hybrid zones and ring species, which challenge traditional notions of species boundaries. The fan of biodiversity is awed by the sheer variety of species, from the 6,000 species of frogs to the 1,000 species of coral, each with its unique characteristics and adaptations. The engineer wonders how species interact and adapt to their environments, with some species, like the axolotl, having the unique ability to regrow limbs. As we look to the future, the futurist asks: what will be the impact of climate change, habitat destruction, and species extinction on the delicate balance of ecosystems, with some estimates suggesting that up to 1 million species could go extinct in the next few decades, as reported by the IPBES Global Assessment in 2019.
