Regarding the origin of animals, the scientific community has not yet fully understood. However, according to existing research results, life originated from some chemical reactions on Earth about 4 billion years ago, initially forming simple single-cell organisms. Over time, these organisms evolved and differentiated into more complex tissues and organs, eventually giving rise to a variety of different types of organisms, including modern animals. The entire process takes millions of years and is influenced by environmental, genetic and other factors.
