Como não recordar Valikangas:
"Life is the most resilient thing on the planet. I has survived meteor showers, seismic upheavals, and radical climate shifts. And yet it does not plan, it does not forecast, and, except when manifested in human beings, it possesses no foresight. So what is the essential thing that life teaches us about resilience?
Just this: Variety matters. Genetic variety, within and across species, is nature's insurance policy against the unexpected. A high degree of biological diversity ensures that no matter what particular future unfolds, there will be at least some organisms that are well-suited to the new circumstances."
