The idea that "humans came from monkeys" is a common misconception about the theory of evolution. The theory of evolution, as proposed by Charles Darwin in his seminal work "On the Origin of Species" published in 1859, does not suggest that humans evolved directly from modern-day monkeys or any specific primate species.
Instead, the theory of evolution explains that all living organisms, including humans and modern primates, share a common ancestry. According to the theory, over millions of years, different species have evolved from common ancestors through a process of descent with modification.
The common ancestor of both humans and modern primates would have existed far back in evolutionary history. It is important to note that the concept of common ancestry is a central idea in the theory of evolution, and it applies to all living organisms, not just humans and primates.
It's also worth mentioning that the term "monkey" is a broad and informal classification that encompasses various non-human primate species, such as chimpanzees, gorillas, and many others. These species are part of a larger group called "simians" or "simiiformes."
In summary, the theory of evolution does not claim that humans came directly from modern monkeys. Instead, it proposes a common ancestry for all living organisms, including humans and modern primates, with each species evolving and branching off over millions of years.
