C. 1 million
years ago.



Answer :

The first ancestors of humans showed up about 4.5 billion years ago. This timeframe aligns with the emergence of life on Earth and the evolution of species over millions and billions of years. The appearance of early human ancestors, such as Ardipithecus and Australopithecus, dates back to around this period based on scientific research and fossil evidence. These ancient hominids paved the way for the evolution of modern humans through a process spanning millions of years. By studying fossils, DNA, and archaeological findings, scientists have pieced together the timeline of human evolution, highlighting key developments and species that contributed to our current existence. Understanding the deep history of human ancestors provides insights into our biological roots and the gradual changes that led to the emergence of Homo sapiens. It showcases the interconnectedness of all life forms on Earth and emphasizes the ongoing journey of evolution that continues to shape our species today.
