LIFE

[CoolJay221]

Is it true that all life came from a single and the same ancester

[MrMistery]

According to evolution, yes

[chicoguardian]

I don't think we came from just one cell alone on earth, maybe spanning across the end of time that we started as one cell and split into many, but with earth, we came from many cells

Is it true that all life came from a single and the same ancester

according to me, yes...singularity.

[trunild]

I think yes!
But our memory is not that strong?

[cool A-level student]

apparently all humans originally evolved in africa too, intrestin huh?
cos thats were our closest buddies are
only 2.4% genetic difference between us and chimps!!!
and yes we all evolved from a kind of prokaryotic cell in which had a single strand of circlular DNA
we've come along way since then
now where the good old eurkaryotic cells with fully defined organelles with there only membranes rather than the mess that are bacteria with everything all mixed together!

[Mjhavok]

We came from self replicating molecules that eventually evolved into the simplest cells. As for if its just 1 cell or 2 slightly different very simple cells. We just don't know 100%.

[playboy bunny]

you have all got it wrong! our parents had sex and that is how we evolved. who needs all the technico stuff!

If conditions were just right to form the initial self replicating ribozyme-ish molecules and their accomanying lipid vessicles, I think that the possibility of simultaneous formation of many of these proto-cells is more probable than the formation of only one and that one surviving long enough to produce an entire evolutionary lineage. The initial presence of many proto-cells would increase the chance of survival. The evolution of sexual reproduction, or at least evolution of mechanisms for injecting and splicing genetic materials, would further increase the chances of survival by having a larger base genome. There's my hypothesis.

[Linn]

geneticaly we are from one common ancestor.
And they were not apes.

[AstusAleator]

No one is going to argue against my multiple ancestral proto-cell hypothesis?

Linn, when you're talking about a single ancestor are you talking about the ancestor of homonids? Or of all life?
If you're going to talk about ancestors of individual clades or phylogenetic trees, then there have been cases multiple organisms forming new phylogenetic trees. Take hybridization and endosymbiosis for example.

how would the conditions be just right?
PS:
thanx for the clarification
all life began each according to their kind as stated in creationism.
