Lab yeast make evolutionary leap to multicellularity

[Praeses]

So you've ignored this part of my post: "Dude even if the yeast retained elements of multicellularity and therefore had a smaller barrier to overcome to develop multicellularity it still demonstrates that the jump to multicellularity from unicellularity could be much easier than we ever thought. The claims of preadaptation are for sure something to consider but they don't change that evolution has occurred here and those changes have resulted in a shift from unicellular behaviour to multicellular behaviour."

Sorry about missing that part. I have sinusitis so my brain feels all clogged
The cells didn't retain elements of multicellular behaviour, it's still part of their life cycle. The title reads "evolutionary leap" which it isn't. Selective pressure can be applied in so many ways e.g. increasing antibiotic resistance etc. Nobody ever claims it to be an evolutionary leap.

You basically just reworded it using E. coli and citrate. The ability to grow on citrate WAS developed.

Selective pressure...and I had a citrate growing E. coli before they did the article, and I never use citrate in my growth mediums besides for a citrate test.

Sure there may have been portions of it still hanging around but it STILL evolved. To then claim that people are trying to "see evolution everywhere" as though there isn't evolution occurring there makes me go :wtf:.

Gene regulation can be tricky. Mutations happen all the time, creating artificial selective pressure will logically select for specific mutants. Sure, it's evolving/changing, but it's nothing to write home about.

Meh no worries. It sucks to feel clogged up. I'm no stranger to that myself

It is evolution. How large you perceive the leap to be is subjective.

Yea but it is still evolution.

I disagree. I find it all very exciting and interesting. The ability for E. coli to redevelop the lost portions of citrate metabolism to allow it survive on a citrate medium is something I find very cool.

I hated Microbiology though. All those cultures and the constant cleaning only to invariably get them contaminated with something in the end made me rip my hair out.

Thanks OP, great article.

The problem is that science is open for debate,

:wtf:
