Sophie looks at one skill in particular that seems to give humans an advantage over all other animals - our superior talent for language. She explores what language really is, and how close other animals come to having it. She considers the world of primates and the theory that some apes may communicate through sign language, and reveals how, even in the womb, humans start to practise making the mouth movements needed for speech. But language isn't just a power to combine words. Professor Scott explores how we convey information through the tone of voice, our accents and the pace and pitch of our speech. But in a world when we regularly talk to computers, she also shows why scientists need to develop machines that can understand the subtleties of our speech. Finally, she looks at language in this digital age and explores the role that emojis play.

For 10,000 years or more, humans created new plant varieties for food by trial and error and a touch of serendipity. Then 150 years ago, a new era began. Pioneer botanists unlocked the patterns found in different types of plants and opened the door to a new branch of science - plant genetics. They discovered what controlled the random colours of snapdragon petals and the strange colours found in wild maize. This was vital information. Some botanists even gave their lives to protect their collection of seeds. American wheat farmer Norman Borlaug was awarded the Nobel peace prize after he bred a new strain of wheat that lifted millions of people around the world out of starvation. Today, botanists believe advances in plant genetics hold the key to feeding the world's growing population.
