The entire "science" of evolution is based upon a small group of theories that are universally accepted by most scientists.
I think Bubba puts a finer point on this acceptance...
"Because of the scarcity of fossils and the discovery of important new finds every few years, researchers disagree about the details and sometimes even basic elements of human evolutionary history." This is true, but it doesn't dissuade scientists from believing in evolution
(Emphasis mine)
Let's see if I can relate to this belief. I believe man, over the course of a few million years, evolved from a branch of monkey, whose species was another mutation from a type of lemur that lived millions of years earlier, and so on through shrews, mammal-like reptiles, amphibians, fish, and cellular plasm creatures....all the way back to a miraculous immaculate conception of a living reproductive cell that came to life from a sloshing of minerals, waters and strobing sunlight.
Now, neither myself or any other scientist has successfully explained how this came to be, nor can any of us agree on what exactly is the organizing force in nature that can create fully funtional organs, breathing, circulatory, and nervous systems, complete DNA sequencing. In fact even the billions of years we have requisitioned for our belief still does not mathemathically support the quantum-fantastic diversity in biology, the astonishing puzzling forms of life manifested, all successfully overcoming an endless series of incomprehensible odds, only to constantly be producing one surprising transmutation after another. Indeed modern genetic and animal hubandry science, a human indelligent design factor that should outwit chance quite considerably, can't even evolve a sheep or a cow into..well another type of animal that isn't a sheep or cow.
Still I believe in Macro Evolution.
Why? Because the alternative would be to believe in someone I can't see.
I would rather believe in something I can't see then someone.
Evolution is the modern name we give for an ancient pagan myth. It's the story men for thousands of years have been telling their tell children about how long ago the animals, including the rational animal man, arose up out of the sea by chance.
What a revelation...scientists are just like people. They believe things.
