Darwin’s law is routinely ignored by those trying to make sense of the fossil records.
For example, the shape of the Tyranosaurus Rex tells us that it was a speed monster. Its enormous hind legs allowed it to run and jump. Most likely, it could turn on a dime by tossing its tail to the side if its pray tried to get away.
Yet the official story is that it could hardly move.
This completely ignores Darwin’s law. The shape of an animal never deviates grossly from its function. An animal with the shape of a speed monster cannot have lived a sloth-like existence.
The Brontosaurus, with its long swan-like neck is another example. The official story is that it carried its head straight out in front of it, and its tail was carried equally straight out behind it. It was a giant walking stick.
Using Darwin’s law we would have expected the Brontosaurus to use its long neck to reach high up into trees. Its tail would be flexible and strong, allowing it to lean back on it as it stretched towards the highest branches.
However, with today’s inertia and gravity, the Brontosaurus would have been unable to control its body in such a graceful way. The torque on its neck would have been enormous, and all blood would have drained from its head.
Even with its neck straight like a spear, problems remain. The fact that the Tyrannosaurus Rex could hardly move tells us that the Brontosaurus would have been incapable of any motion at all. The Brontosaurus was much bigger than the Tyrannosaurus. Its legs would have been crush by its own weight.
The Brontosaurus would have been an impossibility with today’s inertia and gravity.
