How evolution happens - Animorphic changes in the species

Cool video where you can watch species evolve over a half-billion year period in just a little over 5 minutes. Song: "Just As You Imagined" by Nine Inch Nails.

Fun! I think, if I were to level a criticism, perhaps the clip misses out on a beautiful bit of evolution and something that many people misunderstand about it. While each clip shows gradual change in a single figure, that figure actually represents thousands and millions of generations of a species. The driving force of evolution comes from selective pressure through predation, changes in environment, and many other factors affecting survival and reproduction. In these clips, the sharp-eyed viewer might see mountains rising or some such, but it's not really shown to any deep extent. In reality, that kind of thing is what caused the changes - development of legs to walk on the newly formed land, where predators didn't exist, increases in size to allow for better predation on land where the new land animals live, development of leg muscles or standing erect for better types of certain mobility on land to escape said predators...these changes came about not because a single organism simply decided it needed them and grew them, but because many, many generations experienced selection in which the ones without the beginnings of those changes died off gradually.

Anyways, if you think this is cool, go get the NAS's free booklet on evolution.

I'll address a couple of questions at the same time. This video is actually a compilation of cuts taken from a Discovery Channel show (the name escapes me, but I just saw it recently), and the uploader simply put them together and added music. Because this came from a full-length TV show there's obviously a lot of information missing, including helpful narration. In the show they did explain what selective pressures brought about the evolution of these species and the time frame involved in these changes. Notice the time counter in the upper left hand counter rapidly zipping through millions of years as you watch the species change.

Even with missing information this is pretty cool, isn't it?

Cool video but I sure hope that nobody thinks that's exactly how evolution works. (Probably what most creationists think...)

These animations kind of forget that new branches of the evolutionary tree are constantly emerging and species divide into different species with different traits. This video makes it seem like this one fish is the only fish species and its evolution is like a straight line towards becoming a land animal when in reality many different fish species are evolving from the same ancestor.

It's a bit irritating to see people asking the name of the song when it's written right in the description. Why are people so lazy and/or oblivious? I realize the title is wrong in the description, but it's still close enough that a google search brings up a full page of references to the track and album, places to purchase the album, places to listen to the track online and, my personal favorite, the lyrics.

I asked, because either the info wasn't in the original description, or I overlooked it. If it is the latter, I can only say that I am human. Someone quickly answered graciously, and I thanked them.

If you'd like, I could erase my irritating question now that the information has been provided. Since you were able to make a lyrics gag, I can conclude that either you too were "oblivious" and looked them up, or that you are a fan, in which case you are probably personally offended by my horrible, ignorant question. I'm sorry I caused you this great burden.

This would be more powerful if, maybe in a separate thumb-screen, they displayed some of the stages of this branch interacting with their environment.

For example, a large finned fish swimming through a shallow marsh area, using its fins partly as legs to help push and propel it through the reeds.

people are missing the point, this is how evolution works. you're just seeing the successful lineages, that's the point. think of it this way you're own personal greatest ancesotors will have been single-celled organisms, there has been no break in that chain all the way up until you.
the monstrous creature at 280 million years ago is directly related to us.
