ancient life

Ancient life refers to all living organisms that existed millions to billions of years ago. These include simple single-celled creatures like bacteria and algae, as well as more complex multicellular organisms such as early plants and animals. Over time, these life forms evolved, adapting to Earth's changing environments, leading to the diversity we see today. Fossil evidence helps us understand their structures, behaviors, and how life has transformed across Earth's history. Studying ancient life provides insight into the origins of life and the processes that shaped our planet's biological past.
