We didn’t evolve from monkeys - but we do share a common ancestor. The Human species, Homo sapiens, diverged from other primates about 6.5 million years ago.

Recent advances in biotechnology enable researchers to compare species at the level of their DNA and this has produced new evidence in support of evolutionary theory, uncovered previously unknown ways that variation is produced and raised questions that challenge some accepted explanations of evolutionary pathways. Evolution by natural selection is not restricted to living organisms. (Darwin may have realized this; he refers to parallels between the evidence for the development of languages and evolution by natural selection). Any population of ‘things’ that vary in ways that affects their ability to survive can be subject to selection by their ‘environment’, resulting in better adaption to that environment.
