Development of multicellular organism

btw, that exerpt came from Alberts et al, Molecular biology of the cell.

(SNIP) Also very interesting, there are ALWAYS 131 cells that commit suicide of the 1030 somatic cells in the worm. (SNoP)

That is kinda interesting.
In my viewing of television I had also seen someone playout the sequence of someones DNA on a piano..."phonetics engineering" anyone? (It's sort of just a thought...)

Well, isn't that interesting? I am not sure where that comment came from, but anyway: I'd wonder how long it would take to play the sequence of ACGTs and where the T lies on the piano, how the person dealt with methylated bases, mis-matched bases, dimerized thymines, depurinations, missing nucleotides and the boring long stretches of GC islands.

"Selective quotation"...I would suppose...

not always just 131, but always THE SAME 131!

Cheese, you make it sound difficult to understand, needed the 131 to construct itself, and didn't need them thereafter, soooo in a VERY energy efficient manner, it eliminated that which it no longer had use for. After all, why keep cells, that are no longer of any use, FED!

But if I understand the processes of evolution, an organism can't "eliminate" cells just because there is no more use for them. There has to be an adaptive gradient for them to go. Some reason that organisms without them leave more viable descendents than those with them.

Yes, less energy! not having to feed them[/color] Some reason that organisms without them leave more viable descendents than those with them. Construction (team) of a self replicating organism as to be able to leave the viable descendents[/color]

Simply a structural mechanism, like having carpenters build you a house, then they leave, in this case, the cells, they die.

Think about it, life was given, cells died, just so you could be formed, and live.
