species start to differ from each other? like darwin's moths? they were still moths - they could have mated and produced viable, fertile progeny. the finches were still finches, the turtles were still turtles. at best it's subspecies differentiation. as I said, the only way scientists have been able to extend that across the boundary of species is to muddy up the definition of what comprises a species.
and it's hardly a conspiracy theory - it's way too obvious. too many people think they can use science to answer metaphysical questions like whether or not life was created or just began accidentally, as though finding a mechanism for how somehow explains away the why. it doesn't. the fact is, the marxist worldview europeans and liberal Americans like to call "progressive" has no use for God, so the sooner they can remove Him from the equation the better. trying to use science outside of its own purview to 'prove' we all got here by chance is a good place to start.
