Can anyone point me to some material pertaining to the topic of why we don't still see new living cells forming from non living matter? Or to material that shows we do see new cells forming? Are new species (bacterial, single cell organisms) that we find always just evolved from other ones in this day and age? I find it hard to believe that we can't point to something in nature and say "look, new cells trying to form!" Whether they be successful processes or failed ones. Shouldn't whatever processes that lead to cells being formed still be going on? Again, whether they lead to actual living cells or just failed blobs of organic compounds.
Were the conditions on the earth in the past, the environment, just so different and allowed for living cells to form and these certain conditions no longer exist? Is the current environment so different that these processes no longer happen?
If we all evolved from the same single cell organisms...I am just wondering if we have any good explanations as to why the process is so hidden from us. Do we just not know where to look at this moment in time? Unless the process relied on early earth conditions...shouldn't we be able to see these processes still trying to happen?
I am not challenging evolution...or other theories... this is just an honest question that I ask my self anytime I start thinking about early life forming on earth.
I imagine the first cells didn't have DNA/RNA also... is there any information out there that explains how the first cells might have formed DNA (RNA)? Did one particular group of living cells form DNA or did various cells all evolve DNA from their own separate/different processes? Then, if we find life on other planets is there a chance they would have DNA...just maybe with a different sugar? I ask this because if the first living cells on earth formed by some process...and all living organisms on earth now have DNA/RNA... is it wrong to think that that must be the only viable path for life? Do cells form from various processes and all develop RNA/DNA independently... or did a specific group of cells that formed get lucky and evolve DNA and all the other types of cells failed and we just don't see those organisms any more?
I'm just looking for something to read...doing some Google searches for this didn't really get me any where...so if any one out there has any material they think would help me with some of these questions please point me in that direction!
Thanks in advance
