Several million years ago.
In science, there's no such thing as a "mere" theory. |

In common usage the word 'theory' is used to describe opinion or speculation. In science 'theory' and 'fact' are not always different. i.e it is a fact that an apple dropped on earth, has been observed to fall towards the center of the planet, and the 'theories' commonly used to describe and explain this behaviour are Newton's theory of universal gravitation, and general relativity. Evolution is no less factual than relativity, or gravitation. |

It's about time. It would certainly save educated folk a lot of time having to correct the misuse and abuse of the word "theory" by creationists.

Then again a law is not clear either.
Human law is a law because it is consensus; natural law however has nothing to do with consensus. I mean we can vote to abolish or change a human law (like raise the speed limit to 90 m/h), but this would be impossible with the law of gravity. |

Evolution - change over time in heritable traits in a population of organisms - has been observed and tested, and shown to be factual.

But you don't. You extrapolate that definition to put my ancestors climbing out of a swamp (currently) 4.5billion years ago. And that's quite a stretch fromthe definition I just quoted. Now's the time when someone says, "Evolution has nothing to do with life's origins."

No, in all seriousness, is there anyone that can tell me what the inhibiting factor in genetics is that keeps repeated small changes from becoming overall big changes? |

We may have had more/fewer teeth, more/less hair, shorter/taller builds, larger/smaller foreheads, but we've always been human. Much the same way a German shepherd and a Labrador retriever are both breedable dogs. Always have been always will be. Are they different species? Sure. But man created the speciation lines, God created the creatures.
