Any practical use for Universal Common Ancestor?

NWRT

I totally agree. The gaps are where aliens performed genetic engineering to produce a novel organism(s).

I still don't see any connection either - the gaps from sponges/jelly-fish/worms to fish is best scientifically explained by aliens performing genetic engineering.Edited by Dredge, : No reason given.

Not quite - my "aliens did it" theory is an example of sublime science produced by the mind of a deadset genius. Do you realize that many scientists thought Einstein was babbling when he first aired his theories?Edited by Dredge, : No reason given.

Name one.

He should have stuck to designing coastlines, which he had a real talent for - his fjords were pretty ordinary, if you ask me.

"Deadest", perhaps ... I trust you are not comparing yourself to Einstein.And did you realize that people laughed at Bozo when they first thought he was a clown?Oh, wait ...

Genetic engineering of what? Are you saying you think sponges and jellyfish and worms are ancestors of fish?And please do scientifically explain aliens performing genetic engineering.

My evidence is the same as your evidence that life on earth evolved from a microbe - the fossil record. Don't blame me for your lack of scientific understanding.

"deadset", actually. I've corrected it.

So you agree that it is a sensible progression from colonial bacteria to soft metazoans of the Ediacaran and then to Cambrian fauna?And don't blame me for your complete lack of a mechanism.

I stand by my post.

So's your mother.

So your "evolution of the gaps" was just trolli.Those gaps keep shrinking.

Okay. I will copy and paste my answer for you again:

Except, of course, that if the understanding of antibiotic resistance was not the way it is - then the concept of UCA would be incorrect - there would be no evidence supporting it. Which, to rational people, implies that such ideas, theories and practical applications are inherently linked and should not be separated in attempts to make a silly fool of yourself. But sure, buddy - you do you.

It's more linked in the other direction:

​

If anyone could show there is no such thing as evolving from a common ancestor... all our ideas on how to apply biology would be turned on it's head.

​

Message 447
Without the concept of UCA - their would be no point in creating medicine antibiotic resistance the way we do it.
Since we do have the concept of UCA - it helps guide the creation of new medicines antibiotic resistances in helpful directions.

​

That is, if UCA was not applicable - those creating medicine would be using some other idea as a guide, or we would not have 'new medicine antibiotic resistance' at all.

I hope you are able to find it this time. Sane explanation and evidence, again:

Medicine
Schematic representation of how antibiotic resistance evolves via natural selection. The top section represents a population of bacteria before exposure to an antibiotic. The middle section shows the population directly after exposure, the phase in which selection took place. The last section shows the distribution of resistance in a new generation of bacteria. The legend indicates the resistance levels of individuals.
Antibiotic resistance can be a result of point mutations in the pathogen genome at a rate of about 1 in 108 per chromosomal replication. The antibiotic action against the pathogen can be seen as an environmental pressure; those bacteria which have a mutation allowing them to survive will live on to reproduce. They will then pass this trait to their offspring, which will result in a fully resistant colony.

​

Understanding the changes that have occurred during organism's evolution can reveal the genes needed to construct parts of the body, genes which may be involved in human genetic disorders.[6] For example, the Mexican tetra is an albino cavefish that lost its eyesight during evolution. Breeding together different populations of this blind fish produced some offspring with functional eyes, since different mutations had occurred in the isolated populations that had evolved in different caves.[7] This helped identify genes required for vision and pigmentation, such as crystallins and the melanocortin 1 receptor.[8] Similarly, comparing the genome of the Antarctic icefish, which lacks red blood cells, to close relatives such as the Antarctic rockcod revealed genes needed to make these blood cells.[9]

Proof, again:

Proof: You are unable to identify a single YEC who doesn't have the idea of UCA incorporated in their research who is not "useless" in developing drugs and vaccines (medicine and/or antibiotic resistance.)

Why do you think asking the same questions over and over should be given different answers?
I will explicitly tell you now: As long as you ask the same question over and over, I only have to answer it in the same way over and over. Cut and pasting is easy.
Using slightly different words to ask the exact same question doesn't change anything.Have fun!
