Ancient Climate Shifts Drove Flowering Plant Diversity
Recent research suggests that historical periods of intense global warming were primary catalysts for the vast variety of flowering plants we observe today. By analyzing ancient pollen and spores, scientists identified that extreme heat during the mid-Cretaceous and early Cenozoic eras triggered significant evolutionary changes. These findings indicate that while these warm intervals caused mass extinctions, they simultaneously fostered rapid diversification. This process allowed flowering plants to eventually dominate terrestrial ecosystems, fundamentally shaping the botanical landscape of our modern world.
