Current Events > Evolution from single-cell to multi-cell organisms observed in lab

(+) Yeah! (+)

By introducing predation into the environment.

it's just like in dark souls if you beat up a scrub enough times they become a ganker

Up

Cool science bump

How do we know this isn't staged/the cell is a paid actor?

Anti-abortion lawsuits are churning as we speak.

I wonder how many cells it takes for PETA to care.

how does this not have 500 posts, this is the coolest shit, thanks tc

and now being multicellular at all seems kinda weird

let me be free, dissipate my cells

Ok now make a single celled organism from a rock and then Ill be impressed

Haven't they already sort of done that?

awesome

ty. I started browsing CE because football(Vikings vs somebody)

Really made my thankgiving.

Up because every [omitted] on CE needs to know we just cracked open life a little more.

Will someone please explain selective pressure to me so that I can accept that it is a thing?

Up to now I thought I could ignore it. I have always thought evolution just happened and then the useful ones were selected.

However this experiment applied a selective pressure and got

Life is negative entropy and selective pressure moreso?

I get that it's cool, but I don't get how you're getting negative entropy out of it?

Selective pressure is a factor, any factor, that affects how an organism or population survives (and thus how they propagate and evolve). It's the leaves being high on the tree that was pressure on giraffes to select for taller giraffes.

Solitary algae cells can survive slightly better than a "colony", but a colony becomes much more survivable when something shows up that eats the loners.

This helps some. Is it that: The multi-celled would lose if they had to compete with the single-celled for food but the predator?

Pretty much.
