What is the evidence on how singular cell organisms evolved into multicellular organisms? Was this before or after the plant and animal kingdoms split. And is there surviving evidence on the evolution of the spinal column ?

We can actually watch evolution from single-celled forms to multi-celled forms happening.

Plants and Animals evolved multicellularity separately (as did red, green and brown algae, certain bacteria and fungi). The evidence that multicellular organisms evolved from singlecelled organisms comes from multiple similarities of genetics and biochemistry between them. As for the spinal column, evidence comes both from extant variations on the notocord, some fossils (such as Pikaia - the first known chordate) and the development of embryos.

I take it the next step would be for individuals to become more specialized in a colony??

single cell to multi cell shown as de-evolution
Gifts - CafePress A mosaic book which examines the causes of life and death by cobbling various scientific investigations into an unmistakable conclusion: Charles Darwin and creationist prove to be both right and the same. Synopsis Life on our planet has adapted to live in the Antarctic, thermal fissures, sulfur pools, near molten lava (extremophiles), fresh and salt water, as well as Florida and other more comfortable environs. Given that life is so virile and adaptive, why does it succumb to death just because it has lived? By embracing Darwin's work, studying it and determining its limits of application, we are left with a firm understanding of evolution (origin of species). The fit is great and supported by a wealth of evidence. Darwin's theory propels a very accurate understanding of the origin of species but not the origin of life and death. Evolution provides no answers or scientific explanation for the origin of life and death. This is not because Darwin's work is unfinished but rather because evolution has no application here. One of the main arguments employed by creationists against the theory of evolution is expressed in the form of a rhetorical question, how can chance mutations (mistakes) create all the complicated life forms we see? It is a good question. The question's underlying assumption maintains that evolutionists believe that organisms, which more recently evolved, are further evolved, improved and therefore more complex than earlier creatures on the evolutionary path. Indeed, most evolutionists believe this hierarchy of complexity. But what if that very first cell was in fact more complicated than all life that followed? The answer to this question places evolution and creationism on the same track. This book reveals their co-existence with an enormity of sceintific fact. This book reveals that evolution is God's creation to serve the life he also created. Darwin actually does more to prove the existence of a creator than anyone.

Re: single cell to multi cell shown as de-evolution
This has nothing to do with what I was asking, and looks to be preaching instead of looking at the issue.

If facts sound like preaching I am sorry.

It sounds like you're flogging a self-published book with massive internet posting. If you had facts and worthwhile theory you could get published in a peer-reviewed journal. Have you tried the creationist websites? They might be more interested.

Indeed. One of the best known examples of colonies, still living in our present day is alga Volvox. Flagellated single cell individuals form colonies, that move by flagellum propulsion. The cells that are in one pole of the colony specialize in directing movement, using photo sensible spots. The ones in the opposite pole specialize in reproduction. A very common pattern, to be found in most animals, though algae are not in the line of animal evolution, but plants! To find more about Volvox, see this Wikipedia page Volvox - Wikipedia
