My notes suggest that the earliest photosynthesis was around ~3.1 BYA, which
concurrently began to create an oxidized atmosphere.  This in turn started
the extinction of anaerobes and the rise of aerobic organisms.
If these notes are relatively accurate, do we have an ballpark idea ...

    What is the opinion of the members of this group regarding this notion:
    That sexual reproduction, of the kind that Humans practice, may
increase the rate at which a species improves genetically as well as the
rate at which it can adapt to changes in its environment.

I was reading 'Who Goes There?' by Edelson
and he wrote this line, "...life established,
itself on this planet with remarkable speed..."
That suggested two things to me:

Dear reader,
I apologize beforehand if I use poor terminology: I am a programmer in the
first place, with a great affinity for evolution.
I also apologize for posting a long introduction before I arrive at my

The idea of "group selection" as an explanation of altruism among
animals is discredited today among leading evolutionists. This is the
idea that some altruist behaviour is selected because it's beneficial
for the group (e.g. the entire species) the animal belongs to. The

People define life as a replicating process.
I ask what is it replicating? The best answer
is a metabolic system.
Then shouldn't we look for the origin

Dear Sirs and Madams,
The human body has three central weights: the head, the torso or rib-cage,
and the pelvis.  This is like the structure of an insect with its head,
thorax, and abdomin.  But what I recall of university biology was that

Here is a short essay about life and the evolution of life. I just
wrote it to share with people who are interested in, feedbacks are
welcome.

Since other stellar systems may not even exist as we need them, and the
distances between them are so immense, it might be better to unlock the
mysteries of making them, and find the structure in ours that allows for
