what people dont understand is that evolution is based on evolving, obviously...no, we, as humans, did not come from algae, but in the ephereal sense, we did. we had an ancestor that had an ancestor that had an ancestor....*6 trillion ancestors later* that sprouted from algae. A common misconception that anti-evolutionists make is that we didnt come from monkeys, so how can evolution exist? yes, thats true, we didnt come from monkeys. but monkeys and humans share a common ancestor. monkeys are on one branch of the evolutionary tree, and we are on another one.
