Помогите перевести текст Animal Kingdom )
Simple organisms and viruses introduce the simplest living forms and the Animal Kingdom traces the evolutionary path of the multicellular that evolved from such one-celled or organisms. The Animal Kingdom explores the variety and dynamic changes of animal life on Earth We study and group animals according to the similarities and differences in their structures. These structures also show the patterns of change over millions of Simpler animals evolved years. earlier, whereas those with more complex structures and systems evolved later. This pattern of development toward greater complexity shows that evolution is the key to survival. Chance changes meant that certain life forms were better suited to their changing environment. Natural selection permitted the better suited to live, reproduce and pass their adaptations to future generations. This process continues today. Whether that adaptation is a structure such as a backbone, or a behavior, such as the nesting, instinct, it exists because it enhances the animal's chances for survival. In order to study animals, scientists place them into groups or classifications Many species of animals are classified, or grouped, based on whether or not they have backbones. So animals are classified as with backbones or without backbones. This makes it easier for scientists to study the many different species of animals.
