Evolution Of Jaws 1of5

Jawed vertebrates evolved from jawless ancestors over 400 million years ago, and the evolution of a biting lower jaw was a critical step in vertebrate evolution. This series, courtesy of the History Channel, takes us on a journey which explores the diversity of jaw evolution.

THE MOON is mooving away from earth.Actually the moon for about 85 million years ago would have been orbiting 4 yards. above the earth..DO YOU STILL BELIEVE this stupid propaganda called evolution..The earth CAN NOT be billions of years old. Period.

@levonet33 You have been misled. If I can demonstrate to you that your calculations are wrong, will you concede that the source of your information is untrustworthy?

I think I'm going to buy the Evolve DVD set, it is all just so fascinating.

[djarm67]

@iFoamy I would recommend it to anyone.

Hey djarm, where do you get these documentaries from?

[djarm67]

@MusicHypno Various sources. This one is from the History Channel.

@caseagainstfaith It would depend on the situation. In my case, I am a not for profit educational channel which promotes the various documentary channels wherever possible. They also advertise on many of my vids and retain the revenue for themselves.

Unfortunately science education is being treated like an MTV video.

Bombarding the viewer with lots of factoids, but never actualy exploring the facts behind those factoids in any meaningfull way.

I miss the old, 1970s/80s era, presentations on The Nature of Things. They actualy focused on the boring science rather than sensational images.

You know anomalcaris sorry I'll have to check the spelling had a circular mouth and could not bite like that....ah wikipedia.

This whole series is verging on Junk science: it is "predator-centric", yet I am not so sure post-Darwinian theory supports such a Bias: there are far more non-jawed creatures on the planet, from microscopic parasites to viruses... and these seem to drive the evolutionary engine more than a handful of "cool", and conveniently "american" predators. Some real science, please.

@OrthodoxDarwinist: According to tolweb, they are the first clade to branch off the vertebrate clade. But the derivations are not well known here, so lampreys moving up the tree, above the vertebrates, might not be much of a reach.

@puncheex

I don't think lampreys are vertebrates, they barely qualify as chordates :o

''Evolve or die'' ???

''Adapt to....''

Evolution works because of death. survival of the fittest = death to most.
