Because of the Earth tilting on its axis and those catastrophic climate shifts, we had to figure out how to find better food, and we had to learn -- there's Lucy; that's how we all began -- we had to learn how to crack open animal bones, use tools to do that, to feed on the marrow, to grow our brains more.
Vanwege het kantelen van de aarde-as en die catastrofale klimaatveranderingen moesten we beter voedsel leren te vinden, en we moesten leren -- dit is Lucy, zo zijn we begonnen -- we moesten leren botten van dieren open te breken, gereedschap gebruiken om het merg te eten, om onze hersenen te laten groeien.
