AI Thread Summary
The discussion centers on the hypothesis that all life on Earth may have originated from a singular strand of mono-DNA, mono-protein, or a two-component RNA precursor. It suggests that only a few precursors—such as single-stranded DNA, single-stranded RNA, or their mirrors—could potentially lead to the emergence of all life forms over time. The theory posits that a self-replicating protein, formed under conditions like those found at hydrothermal vents, could replicate its own RNA/DNA template, thereby generating all current and future life on Earth. The conversation invites further exploration of alternative postulates regarding the origins of life.

What are the possibilities that all Terran life originated from a singular strand of mono-DNA or singular mono-protein? :rolleyes:

What are the possibilities that all Terran life originated from a singular strand of mono-DNA or singular mono-protein?

or two component RNA precursor?


Affirmative, according to my level of understanding of Genetic Genesis, there are only two or three two-component precursors possible that is capable, given enough time, of generating every lifeform on Terra:

1. Single stranded DNA or component protein.
2. Single stranded RNA or component protein.
3. Single stranded DNA/RNA component mirrors with component proteins.

For example, given that a single self-replicating protein was somehow 'forged' from component materials under hydrothermal conditions, (an ocean floor hydrothermal vent) , or other possible sources, in which that protein was capable of replicating its own RNA/DNA template.

For example, a protein that replicated a RNA/DNA template, in which that template replicated an exact copy of the original protein, should have been enough, given enough time, to have generated/produced all past, present, and future lifeforms on Terra.

Is there another possible postulate? :rolleyes:

Thread 'I need help understanding this quote about recent Natural Selection'

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...
