Scientists suspect that the shape of human hands evolved over time. Those with better manual dexterity had an advantage in tossing a spear, making tools or throwing a rock in order to get the food they needed to survive. Given the usages of “the hands today” (video games, texting, social media etc.), what prediction would you have about “the hands of the future”? Explain your prediction.
