Can we call a multi-cellular organisms just 'colonies' of cooperating single cells, a single superorganism? (like ants)

Do we see symbiotic relationships fuse into one organism?

Just musing

[cassiopeiaproject]

There are such colonies of "cooperating" single celled organisms. But multi-cellular organisms have cells of different types. Muscle cells are different from neurons and blood cells. When cells are differentiated like this, the resulting multi-cellular organism has evolved beyond the colony stage.

Symbiotic relationships can and do sometimes "fuse" into one organism.

cool information. evolution is so complex but interesting. how do these changes occur is what i want to know. is it simply genetic mutations that pass their genes? if so when will humans have their genetic mutation because we have a rapidly changing environment

[cassiopeiaproject]

The question of "how does it occur" is covered in more detail in the complete set of our evolution videos, but in short -- variation in the genome is caused by mechanisms like transposons, retroviruses, replication errors and others. When these variations happen in the DNA of egg or sperm then they are passed on to the next generation. Then given this variation, natural selection and genetic drift sort out the changes that will endure.

do you make your own animations

[cassiopeiaproject]

Yes we do a lot of our own animations. Sometimes we buy a 3D model and animate it ourselves and less often we purchase the complete 3D model with animation.

I'd like to see the first minute of this video explained in much more detail. Obviously the universe possesses certain properties that led to life, but I can't see how those properties came about in the first place. I'd love to know the answer to this.

@Iberedmas what's your source? has it passed the peer reviewed scientific method?

[TCupUK]

What happened to all the oxygen used to bond with hydrogen to make water?

How was there no oxygen in the Air?

[burkerow]

@givehope2lives I had a little problem with the use of the word "miracle" also, but the word can also describe a statistically unlikely but fortuitous natural event.

As for the use of "somehow", I don't see that as having any religious connotation. There is nothing wrong with saying "somehow" to say "we don't know" how something happened. It's not deferring to the supernatural.

[serote1979]

There is a human face in the rocks when the oxygen is bubbling up. Anyone see it?

[givehope2lives]

during the first 30 seconds I heard the words "miracle" and "somehow" lol, and I thought religion was the only theory based on faith.

[Alpha6059]

Very good information in this video!

[patsyd80]

Oh man ......what a great video to watch when your stoned.

[Iberedmas]

you have no idea what you are taking about. there was life before Big Bang and after big bang Adam was created . And Eve was created before Big Bang. And Allah(God)(Amlakh) did all these.
