Masha is eleven and Max is nine. They intend to become super popular science bloggers, win the competition for the best children's science channel and go on a real dig. Children start a YouTube channel - Science Ninjas, where they talk about scientific discoveries and facts, and at the same time find out for themselves: - Where did the person come from? Why don't monkeys turn into humans now? - Where did the monkeys come from, did they come from dinosaurs? And from whom? - Why did some monkeys become people, while others remained gorillas and monkeys? When and how did apes become human? If you want to laugh heartily and understand anthropogenesis, this book is what you need!
