In chaos theory, they say the infinitesimal flapping of a butterfly’s wings can hypothetically cascade into a fierce tornado. Now, scientists have demonstrated how some of the smallest creatures in the ocean could have the same outsized impact under the waves – with swarms of marine organisms inadvertently producing powerful currents that mix and churn
