Even before Darwin, biologists recognized that species that looked quite different as adults often had close similarities as developing embryos. Many four — legged animals go through embryonic stages that have similar features — gill arches, a notochord, segmentation, and paddle-like limb buds — as they develop into different adults. To Darwin, the embryonic resemblances were strong support for the theory of evolution. One of Darwin’s contemporaries, German biologist Ernst Haeckel, summed up the argument in a famous, pithy statement: “Ontogeny recapitulates phylogeny.” That is to say, in the process of development, an individual passes through the adult forms of all its ancestors. So, Haeckel proposed, by examining the development of an embryo you could read its entire evolutionary history in the transition from one stage to another. In fact, this isn’t strictly true, and the drawings Haeckel made exaggerated the embryonic similarities between species.

Heh,heh. Take a closer loos at the fairy tale that is Macro Evolution that says “all animals came from a common ancestor” and that is magical flipping of switches to make one animal magically another. Evolution is another myth pulled out of an ass of someone trying not to be religious but still grasping at straws with pseudoc reationist bullshit. Totally unscientific to make such claims like Man came from apes then ‘finding the proof” with the likes of “lucy”

But saying there was a Magical Big Bang cause someone pulled that idea out of their ass and then Hubble had red shift in his data to “prove it” and “man came from Apes” out of ass then finding “Lucy’ as “proof” is just as irresponsible and unscientific. Humanoid bones does not a Human Ancestor make, and with the Earth spinning and going around the sun,sun going around galaxy,galaxy going round galactic cluster, there is a shit load of “red shift” that don’t mean shit.

I’m not going to argue science with a person who believes in magic.

Actually oxygen was mostly likely poisonous at the start, firs organisms produced first energy out of other elements, like Sulfur.

Well, good, because if you believe in the bullcaca in this video, you don’t know anything about science, either.

Its the 21st century jackass. When you want to come join the rest of us please feel free.

Oooh! I’m a “jackass.” What a crippling argument.
Why don’t you go back to your Shaolin testicle training? The adults are talking.

Neo, somebody clicked “spam” on you. Maybe we should stoop to their level and click “spam” on all of their superstitious propaganda. That must be what jesus would do.

and isn’t that comforting to know… that we never will have all the answers… because that makes God who God is…. some “ONE” with a lot more know-how and know-about that we have or ever will have. the more that science “discovers,” the more impressed I am with God

This “bullcaca” is scientific theory based on physical evidence that, after being tested and studied thousands of times, always points to the same conclusion.

The more science uncovers, the greater is my utter contempt for the unimaginative, parochial and petty concepts enshrined by the concept of God.

Religious people who actually believe their books to be the word of a God need to get a huge dose of reality before they try and commit a little self-prophecy and destroy the world.

“…they try and commit a little self-prophecy and destroy the world.”
Silly rabbit…little humans have not that kind of power even with nukes….the planet will continue even if we obliterate our very selves. Did you just graduate from kindergarten?/ Honestly!
March 8th, 2009 at 10:05 pm
“because that makes God who God is” Which god are you talking about and what evidence do you have for its existence?

The problem is not their belief in their religious books, but their refusal to realize the world has changed on the past 2000 years. The knowledge that has been gained in those years as improved our understanding of the world. However, no new information has been added to their book.
The most disturbing thing is that they take their religious view on faith, not facts or evidence. Then use their hatred to ‘destroy our world (the society that humans live in).’

Those embryos look tasty. Id like to deep fry them and eat them like chicken wings
August 10th, 2009 at 7:50 pm
all vertebrates share a common ancestor which lived during the early cambrian. some 530 million years ago.
August 18th, 2009 at 10:53 pm
it should be noted that embryos would turn to mush if you tried to cook them.

Goddam mutants! Get away from me, devils!
January 26th, 2010 at 1:28 pm
@omiteru, oh really? So, are we to change the Word of God every so often to keep up wit new ideas and knowledge to satify man’s futile thinking? The fact is we do not have ‘common ancestor’, but a common Creator. And the Bible is The Truth, and it remains Truth til the end.
January 26th, 2010 at 4:58 pm
People need to take Evolution theory by faith as well. Haeckel’s embryos diagram was proved to be false yet many modern science books still print it as true. Before the Cambrian explosion, there were jellyfish, sponges, and worms. Then, bang! We see arthropods,echinoderms,chordates. Mammals came later, but the chordates,the major groups to which they belong, were right there in the beginning of Cambrian, contrary to Darwin’s tree of life.
January 27th, 2010 at 7:22 am
Correct me if I’m wrong, but from my studies, they quit using Haeckel’s embryo’s within the past ten years…
And I disagree that science of any kind needs faith. I believe it takes understanding…and understanding is susceptible to change…
January 27th, 2010 at 9:24 pm
Actually, they r still printin Haeckel’s embryos diagram in tex books, some in color or some variation. But they still pass it as valid, even though many scientists take issue wit it. While understanding is susceptible to change, science( as pertaining to evolution) is passed off as factual, and the only truth that can be considered reasonable, n empirical. But evolution does take faith to believe somethin came out of nothing, non-living produced living creatures, all came from common ancestors.

Science in not the same as religion.
Nothing can be gained by comparing different religious belief or deciding with religious doctrine is correct. It is the individuals choice what religious belief they have and they should be respected for that.
Science is an enterprise of discovery and understand the natural (material) world. The Cambrian explosion, embryos are all just one word in any book in the library of science.
Evolution is a science that is dependent on all sciences and itself.
