over me in this thread, as though I were mere vermin. People should
be able to judge for themselves just how far off base he is.

This is closer to the truth than Genesis, which already had fruit
trees with seed in their fruit on the third day. But unless "herbs
and seedless plants" refers to algae (and also cyanobacteria, which
used to be called "blue-green algae") he is just a small improvement
on the authors of Genesis.

As one can see, this medieval Islamic writer was way off the mark.
Shellfish predate even the primitive vascular plants by well over a
hundred million years. As to palms and vines--forget it!

Palms and vines morphing into snails and shellfish? I hope that
isn't
what this medieval writer was trying to say, especially since his
last

Did you have me in mind? If so, your question is completely wasted.
I don't expect us to have answers to any of these questions for the
next 10,000 years except the "when" of prokaryotes [bacteria and
archae] to which I think we may get an answer of "3.9 billion years"
if we send out enough instrumental probes on flybys in that time
period.
The questions I am asking have a far better chance of being answered,
even within the next century, although I don't expect a huge amount
of
progress in my lifetime. They have to do with the relative
probability of four different kinds of hypotheses:
(1) Earth organisms are due to abiogenesis that took place right here
on earth, without any outside intervention.
[The remaining three have to do with directed panspermy:]
(2) Earth was seeded by a species that had pretty much the same
genetic code we do. ["The Xordax Hypothesis."]
(3) Earth was seeded by a species that had a biochemistry based on
protein enzymes, but a much simpler genetic code than ours. ["The
Golian Hypothesis"]
(4) Earth was seeded by a species whose own biochemistry was based on
nucleotide-string enzymes, perhaps RNA ribozymes, perhaps with a
translation mechanism for producing simple structural proteins. ["The
Throom Hypothesis"]
In assessing the relative probability of (2), (3) and (4), there is
on
the one hand the fact that the initial efficient self-replicators,
without the intervention of intelligent design, are easiest to
envision in (2) and hardest in (4), but then the probability of
evolving intelligent life from that basis comes in just the reverse
order. And so, it's a tossup at this stage which is the most
probable
and which the least.
The three probabilities then combine in some way in any assessment of
which is more probable, homegrown abiogenesis ("Mother Earth did it")
or directed panspermia.
================= end of repost
And now, I should add that Boikat has mentioned a fifth possibility,
undirected panspermia. May the best hypothesis win.
