Scientists challenge theory on emergence of intelligent life on Earth

Scientists are challenging the "hard steps" theory, which claims the emergence of intelligent life on Earth was highly improbable. A new study suggests that life may develop predictably when planets have certain habitable conditions, rather than relying on numerous lucky breaks. The research team argues that the evolution of Homo sapiens followed a series of "windows of habitability" driven by environmental changes. They believe that once conditions were right, the path to intelligent life could occur relatively quickly. This study raises questions about whether humans are a rare cosmic fluke or a likely outcome of planetary evolution. Researchers are also exploring the potential for life on other planets, with many exoplanets identified as having conditions suitable for life.
