The process of the evolutionary development of humans from a common ancestor with monkeys is called "primate evolution" or "human evolution." Primates are a group of mammals that include monkeys, apes, and humans. The shared ancestry among these groups is well-supported by scientific evidence, including fossil records and genetic studies.
Around 6 to 8 million years ago, there was a divergence in the evolutionary path of the common ancestor of modern humans and modern apes (including chimpanzees, bonobos, gorillas, and orangutans). Over time, this led to the emergence of distinct lineages, with one lineage eventually giving rise to modern humans (Homo sapiens) and the other to modern apes.
It's important to note that humans did not evolve from modern monkeys; instead, both modern monkeys and humans share a common ancestor from the distant past. The study of primate evolution is a fascinating field of scientific research that helps us understand our origins and the evolutionary journey that has shaped the diversity of life on Earth.
