Quotes & Sayings About Keystone Species

Many of the medicines we use today, to fight everything from AIDS to cancer, originate as a toxin in an amphibian skin. When we lose these animals, we lose resources. We lose keystone species in the environments where they live. — Jeff Corwin

No comets crashing, nothing you could really call a nuclear war. Just everything else, tangled in the changing climate: droughts, water shortages, crop failures, honeybees gone like they almost were now, collapse of other keystone species, every last alpha predator gone, antibiotics doing even less than they already did, diseases that were never quite the one big pandemic but big enough to be historic events in themselves. And all of it around people: how people were, how many of them there were, how they'd changed things just by being there. — William Gibson

That all species are related in the flow of life and death is a keystone of evolutionary theory. The grandeur displayed in this view of life is ecological in character. — Elizabeth A. Johnson

Precisely when hominins learned to manipulate fire is unclear. But recent research suggests that fire, in the form of cooking, helps account for the leap into the genus Homo, who became physiologically dependent on cooked food. By boosting calories, and by detoxifying and softening food, controlled fire allowed us to exchange big guts for big brains. Experiments confirm that we cannot thrive or reproduce on raw foods alone: they simply cannot deliver the calories and they require more chewing, digestive juices, and intestinal machinery. With cooking that digestive process begins earlier. If the observations hold, they say that humans and fire have not simply co-existed but co-evolved. We are not only the keystone species for fire: fire is a keystone process for our existence. — Anonymous
