Questions Regarding Evolution

No ... Discussion is at a standstill because you're simply repeating the same question over and over ...
How is citing a number of examples for discussion asking the same question? 'Over and over'?... Ridiculous, that never occured. Is it not your own philosophy which determines it to be one question? Original question awaits an explanation.
 
If we return to the underlying 'extremophile' publication, it's assuredly, quite the most extraordinary creature. 'Questions Regarding Evolution'?.... that's exactly it... So, what created our recently revealed discvery? What could have existed so long ago, with that capability? What was the purpose of doing so?

It’s all about survival. A variation that gives even a tiny advantage in survivability means the individuals with that variation are more likely to survive. If they survive and breed they pass the alleles for the genes on to their offspring. More of them survived to breed so there are more copies of these advantageous alleles around. But even in the offspring there is variation and some will survive better than others so there are constant tiny changes from generation to generation, potentially individually insignificant but over thousands or tens of thousands of years or generations the individual tiny change should all mount up to make a big change when compared to the original form.
 
If there are commensal or symbiotic or parasitic relationships that have come to be over time, none of them are engineered. As others have eloquently stated, the alleles that create certain phenotypic traits, or genetic combinations and mutations that arise either benefit the organism or don't. If a particular trait is selected for by circumstances that creates more viable offspring that are able because of their characteristics to survive, they do and are able to reproduce, and the others don't, and gradually die out. The rate of change can be fast or slow, and genetic drift can also occur if two populations are separated and not interacting --eventually they might create a new species or subspecies.
 
Fantastic and much appreciated responses. I guess the underlying question is... where did the original creation originate... Which, of course, takes us back to the elemental question, how could the universe evolve from nothing and what has driven the complexity of life on our planet.

The complexity of life has been driven By changing environments and competition fuelled by variation and mutation. Original creation well we have ideas but...

Guess what is so frustating... is that we given to understand the questions... and the answers eternally outwith our reach...?
 
If you follow evolution to its logical conclusion, i.e, at one time there was only ONE single nucleous, (how did that form) then the timescale for the formation of all life on the planet is truly mind bending, given the time it is supposed to take for the smallest change in any life form.

So mind bending that it is reasonable to question it.
 
It's possible that the original cell(s) may have been a commensal or symbiotic relationship of a couple of separate bacterial cells such as proto-mitochondria that began working together as organelles to form larger animal cells within a cell membrane. The earliest cells were prokaryotic bacteria, and over time developed a membrane-enclosed nucleus; membranes were possibly key to allowing cells to exist and to create multicellular organisms.
 
feinman,

Even if that were so, it happening in one puddle on some patch of land somewhere would be strange enough, but to scale up to the whole World in the time the planet has been here is another thing.

And by every life form I am including plants.
 
Without predators, a few house flies could produce enough descendants in 5 months to literally cover the globe.
 
What would the house flies be using for food ?

That argument doesn't hold water.
 
There are creatures which simply snack on minerals.
