If this analogy with Biological Evolution has any validity, then -
How many Elements are entirely "marine"?
How many are only "terrestrial"?
And how many are "amphibious"?

Let us consider our solar system.
Via spectroscopy, we find all the naturally occurring
elements through Uranium (perhaps not 43 Technetium,
as it is the atomic number element without any stable
isotopes). The H, He and Li mostly came from the first
three minutes of the big band and the rest from
exploding stars long before our solar system formed.
We estimate that our solar system is 4.56 billion years
old based on the oldest rocks--Carbonaceous chondrites.
So everything was here from the "start" of our solar system.
An important unanswered question: Did life find safe
harbor of one or more of the solar system bodies (Earth,
Mars, Titan, Europe, Enceladus, etc.)? Or does did life
get started dependent time/places in the solar system.
Life has evolved following Darwinian principles.
If you want to talk about evolution of elements, the
mechanisms for the creation of heavy elements via
nuclear reactions is somewhat understood.
If you will remember, most H, He and Li were created
in the big band. Elements up through the iron group.
[ like Fe, Co or Ni at which level no more energy is
radiated ], are created via fusion processes [aka
nucleo sythesis ]in the cores of stars.
Heavier elements yet in supernovae.

Now Sam, to sustain life, also detail why every multicellular,
oxygen-consuming organism/lifeform uses iron (Fe) in
its Blood, barring a few sea creatures that use Cobalt.
= Iron is an utterly fascinating element:
=1= Fe catches & releases the oxygen in the blood's Haemin.
=2= Iron, as a metal, is very durable und is used to house,
transport and defend ourselves.
=3= Iron is also an extremely volatile element when it combines
with carbon monoxide into Iron penta carbonyle (Fe(CO)5.
=4= Fe(CO)5 is formed in interstellar dust clouds where
it sythesizes with H, O, C & N, most of the needed
amino acids that are necessary for protein formation.
=5= Fe(CO)5 is produced in industrial quantites here
on earth and is a liquid that boils at 103°C, roughly
the same temp as is water.
=6= Fe(CO)5 is extremely toxic, while other Iron compounds
are essential for life to exist.
=7= Iron which was born in the final labors of a dying star
gave you the gift of life and it rules over your existence
with its... well... iron fist!
Take care, you guys, Merry Xmas & laugh as long as you
still can.... ahahahaha... ahahahahanson

# So, all the elements of the Periodic Table are present in our Sun, even if
in tiny quantities, or in similar fiery bodies in outer space? Proven, or
assumed?
What is the difference between a solid, a liquid, and a gas - but
dispersion of atoms or molecules. With further increase in temperature can
atoms disperse/split?
Conversely, is a drop in temperature needed for some elements to form?
Hydrogen constitutes only a small percentage of the Earth's crust - now.
But that is because most hydrogen on earth is tied up in water, and in
living things.
If hydrogen is the most primitive element, and Nature is a causal
process, then it is reasonable to assume all the other elements came from
primitive hydrogen. Unless they were all formed simultaneously, and
immutably.
If the Periodic Table is indeed periodic, this may be due to elements
being constrained by a limited number of possible "properties" in their
habitat, and doomed to repeat them.
While the atomic stability of the inert (now noble) gases is the aim, it
is the restless nature of things for a new "period" to commence, and again
seek inert gas stability.
In a Dynamic Universe, everything tends to "evolve" (ie. change), due to
causal consequences, but if the Elements are limited to the 100+ we know of,
then this is because of the laws of atomic association (proton, neutron,
electron)?
Any dynamic universe must function according to some type of laws/rules,
to operate at all, but does this imply a Lawgiver? Or does that only put
the question one stage further back? Same with Big Bang - what existed
before? Nothing?
And if the universe had a Beginning, does it thus have an End?
