This book covers everything from the classification of animals and plants to the relationships between humans and animals, and animals and the environment, ultimately exploring the state of our planet's environment. With witty and engaging illustrations and comic-style content, it encourages readers to think more deeply about animals and Earth's environment. English summaries are included throughout the book, along with animal-related quizzes and vocabulary explanations. As environmental changes intensify, food security will become an even greater challenge for humanity. This book offers not only knowledge about animals and the animal kingdom, but also an opportunity to understand and feel the inseparable connection between animals, human survival, and the environment. *Adapt to Survive The theory of evolution is based on the idea of 'natural selection' — that living things change their bodies to suit their environment. For example, giraffes didn't get long necks simply to reach leaves high up; rather, by avoiding competition for food and eating leaves that were higher up, their necks gradually grew longer over time. The ancient ancestor of whales was a land mammal called the 'Mesonychid.' How did a land animal transform into a creature that lives in water? Long ago, the ancestors of whales likely struggled to find food on land, or perhaps they were constantly fleeing from many predators. To survive, they needed to find new food sources or places to hide — and eventually discovered that water was a safe refuge. As whale ancestors began spending more time near water, their bodies gradually started to change. At first, their snouts grew larger to help them catch fish, and later, their front legs and tails transformed into fin-like shapes for swimming. *Animals of the Desert Deserts are scorching hot during the day and drop sharply in temperature at night. This is because sand absorbs heat quickly during the day but loses it just as quickly at night, creating a large temperature difference between day and night. Camels are among the animals best adapted to the hot desert. They can go up to two weeks without drinking water, thanks to the moist fat stored in the hump on their back. Wide feet that prevent sinking into sand and long eyelashes that block sand and wind have made the camel a true guardian of the desert. Most desert animals are nocturnal, avoiding the scorching heat by staying active at night. Scorpions hide beneath rocks during the day, while lizards and fennec foxes wait out the daylight hours in sandy burrows. Fennec foxes, in particular, have developed large ears due to the climate — when their body temperature rises above 40 degrees Celsius, their big ears help release heat and cool them down. Their ears are lined with a web of tiny blood vessels, making temperature regulation easy.
