it would look like your mum

Check out Wikipedia page for Ediacaran biota. The ancestor might look something like those. The fossil records from that era aren't very abundant and clear though.
it would be the common ancestor of both vertibrates and invertibrates
a sort of invertebrate fishlike thing
Like this?

first result on google, some kind of worm
Those might give a hint.
The last common ancestor of the cockroach and human must have diverged before the Cambrian era, because the ancestor of crustaceans (from which insects evolved) and vertebrates existed during Cambrian.
The common ancestor must have at least these properties:
-bilateral symmetry of body
-body is composed of segments
-mouth and anus are separate
-has coelom
-there's some cephalization of nervous system
This is creeping me out. The fact that there's a life form so distant from me that our closest common ancestor would be pre-cambrian. It might as well be from another planet.
probably something like this:

dude, a bunch of life forms on earth are like that. Get over it.
I think that thing in the middle still exists
>there's a life form so distant from me that our closest common ancestor would be pre-cambrian
And our closest ancestor with Plants is Unicellular.
>ywn travel back in time and look at Cambrian fauna IRL
That's Precambrian.
Whatever, I want to walk among organisms that are so different from us, they might as well be alien -- except I know they're the precursors to what will become humanity.
I'd also like to be able to walk among like ancient Sumerians or Babylonians or whatever, old civilizations, to see what it all looked like back in the day.
Good post

Me on the left.
You'd just step on one and erase all terrestrial animals from history.

Our closest ancestor to plants is unicellular but it's not a protist.
Man has truly conquered nature
I really want to punch an Anomalocaris in its stupid goddamn face so badly.
You mean ?
Ew...
Thats what
