If you look at the universe and study the universe, what you find is that there is no evidence that we need anything other than the laws of physics and the other laws of science to explain everything we see. There's absolutely no evidence that we need any supernatural hand of god. -- Lawrence Krauss, World-Renowned Physicist
There is probably no other notion in any field of science that has been as extensively tested and as thoroughly corroborated as the evolutionary origin of living organisms. -- Encyclopedia Britannica
FAITH. No one word personifies the absolute worst and most wicked properties of religion better than that. Faith is mind-rot. It’s the poison that destroys critical thinking, undermines evidence, and leads people into lives dedicated to absurdity. It’s a parasite regarded as a virtue. -- PZ Myers
Religion is the antithesis of science, an anesthetic for the mind that disables critical thought and encourages the acceptance of inanity as fact, and wishful thinking as evidence. -- PZ Myers

Why do many whales have legs and pelvic bones separated from the rest of their skeleton? These vestigial organs are powerful evidence for evolution.

This blog now has 67 posts about the evidence for evolution. The people who most need to study evolution, the world's Christian assholes and Muslim terrorists, will never study any of it because they are proud of their cowardly fear of reality.

One of the most powerful (and most easy to understand) evidences for evolution are vestigial organs, which are also popular with the professional liars for Jeebus because they like to deny their existence. These dishonest assholes for Jeebus would have a difficult time lying about vestigial organs in whales and so they usually just ignore this evidence. If they lie about it anyway at least they don't have to worry about their idiot customers using logic or checking facts. Christian tards love their professional liars because they make them feel good about their incurable mental illness.

As everyone who isn't a religious idiot knows, whales are descended from land animals, and the fossil record of this transition is now complete thanks to recent discoveries in Pakistan. But even without the fossils and even without the DNA evidence that shows beyond any doubt modern whales are cousins of modern hippos, people can easily figure out the ancestors of whales lived on land. All they have to do is look inside a dead whale.

I'm going to let Jerry Coyne (a biologist at the University of Chicago) take over here. I challenge evolution deniers to defend their dead Jeebus after reading this paragraph from page 60 of Jerry Coyne's Why Evolution is True.

Whales are treasure troves of vestigial organs. Many living species have a vestigial pelvis and leg bones, testifying, as we saw in the last chapter, to their descent from four-legged terrestrial ancestors. If you look at a complete whale skeleton in a museum, you'll often see the tiny hindlimb and pelvic bones hanging from the rest of the skeleton, suspended by wires. That's because in living whales they're not connected to the rest of the bones, but are simply imbedded in tissue. They once were part of the skeleton, but became disconnected and tiny when they were no longer needed. The list of vestigial organs in animals could fill a large catalog. Darwin himself, an avid beetle collector in his youth, pointed out that some flightless beetles still have vestiges of wings beneath their fused wing covers (the beetle's "shell").

  1. Please correct me if I'm wrong but do only male whale's have the vestigial leg bones? Because I heard somewhere that female whales don't have any. And if they dont have any than the evolution of the whale is false.

  2. Mr. Bell, I never heard that before and it makes no sense. There is absolutely no reason I can imagine for only males, and never females, having vestigial leg bones.

    And even if these leg bones (found on some but not all whales) were not evidence for evolution, there's tons more evidence that shows whales evolved from land animals, including the impressive fossil record, and including undeniable evidence from comparisons of DNA sequences that show whales and hippos share an ancestor.

    Also, the only alternative to evolution I have ever heard of involves magic, and even children know magic is just a fantasy.
