Post by MarkEPost by MarkE"Here we infer that LUCA lived ~4.2 Ga (4.09–4.33 Ga) through
divergence time analysis of pre-LUCA gene duplicates, calibrated
using microbial fossils and isotope records under a new cross-bracing
implementation. Phylogenetic reconciliation suggests that LUCA had a
genome of at least 2.5 Mb (2.49–2.99 Mb), encoding around 2,600
proteins, comparable to modern prokaryotes."

Early earth able to support life 4.3-4.4 Ga?
This would give a time frame for the evolution from the origin of
life to LUCA of a few hundred million years at most, i.e. zero to
2,500,000 base pairs encoding around 2,600 proteins.
Not enough time?
Not the rate predicted by evolutionary theory?
Or all good?
I put up this article last year when it was first published. What you
should be worried about is that the origin of life is definitely not
Biblical. You seem to be worshiping the wrong god, or is the one
responsible for the origin of life the pretender god? Maybe the Bible
is just wrong about everything that we can determine about nature.
You are the one that needs to decide how you are going to deal with
reality.
The paper does admit that their results would indicate that there
would only be a couple hundred million years for life to evolve on
this planet, but there is the option that it first evolved somewhere
else like Mars. Look at Figure 1. That could also explain why only
two lineages (archaea, and eubacteria) survived, and why it looks like
it took a billion years before those two lineages started to diversify
on earth.
If life did not get to earth before 3.2 billion years ago that would
explain the lack of diversification within Archaea and bacteria.
The alternaitive is that LUCA existed over 4.2 billion years ago.
Diversification occurred for over a billion years, but sometime around
3.2 billion years there was a mass extinction event and only one
lineage of Archaea and one lineage of eubacteria survived to diversify
after the mass extinction event.
Neither scenario is Biblical even if you claim that some designer
created Archaea and eubacteria 3.2 billion years ago in a way that
makes it look like their common ancestor existed for a billion years
before they existed.

Thanks Ron for the summary; interesting science and process of
deduction. As far as compatibility with biblical theology goes, does not
an old earth interpretation allow for this? Personally, my reading of
the science is old earth with significant interventions re life. YMMV.
Btw, is this you? https://www.researchgate.net/profile/Ronald-Okimoto-3
The old earth interpretations try to account for the origin of life by
claiming that the Bible doesn't say anything about how life arose on
this planet. They have to lie in order to reinterpret what is written
in the Bible. The Bible is pretty clear as to how life was created on
this planet. Land plants, including agricultural crop plants were
created on the third day (period of time for old earth creationists).
The sun and moon, and the sea creatures were created on the fourth day
or period of time. This is inconsistent with how life arose on this
planet. We know that sea creatures including vertebrates were created
long before land plants evolved from fresh water algae, and that dinos
were walking around before angiosperms (flowering crop plants) evolved.
The Reason to Believe old earth creationists used to claim to be IDiots,
but they claimed that they did not want to teach the junk in the public
schools. They only wanted to use the fraud of ID science to support
their Biblical beliefs. After the Top Six came out in 2017 they seemed
to have stopped being IDiots, and you would be hard pressed to find any
indication that they were once supporters of the ID scam. They no
longer mention it on their home page, and when I searched "Intelligent
Design" on their web page you don't come up with many of their old
papers on the subject.
Any science confirming the Top Six best evidences for IDiocy would not
be Biblical. It would be just more science to deny. The Reason to
Believe creationistss still want land plants to be created before sea
creatures. Not only that, but they have some weird interpretation of
some other part of the Bible (not Genesis) where they claim that whales
were created with those first sea creatures. They deny that terrestial
mammals had to have existed before whales evolved.
This is the type of denial that has to exist to try to fit the Biblical
interpretations into what reality actually is.
I never maintained that researchgate page. I recall that I may have
signed up years ago because a research associate wanted me to. I do not
recall ever going to it before I clicked on your link, and it isn't
accurate. I wouldn't know how to fix that page. I retired from
Cobb-Vantress last year.
I try to delete the papers that I haven't been associated with on the
Google Scholars page, and it may not list all my publications. I've
never tried to add anything to it, just delete the papers that aren't mine.

Since I no longer have the Cobb-Vantress email I probably no longer have
access to that Google Scholar page. I was able to edit affiliation to
"Retired" but I can't seem to change the verified email address.
