Point us to a "valid scientific paper" in which ACTUAL EVIDENCE FOR abiogenesis has been published in the past year. Without abiogenesis, evolution is empty and useless, is it not?
Another bad year for religionists
- Thread starter evoguy313
- Start date
Not in the least.
It is a common bit of creationist disinformation/desperation to demand that abiogenesis is linked to evolution, or that evolution needs abiogenesis. The ToE deals with the origin of species after life had begun. Pretty standard stuff.
Of course, I can present this from just the last few years, just from one researcher and his collaborators - and please note, not a single one of them is merely attacking some aspect of creation, while nearly every creation/ID paper I have ever seen has attacked evolution and NOT presented evidence in favor of YECism:

Ah... So you were telling fibs before, you naughty boy. Your question was answered, but you didn't like the answer, it was a "coloring book" answer.
You are admitting that we did answer your question, but that you did not like the answers you were given.
All you have to do now is to be specific about what you don't like in our answers so we can fill in the details you want to see. Yes, that does mean you will have to do some work deciding where you want us to be more specific.

So, you have no specific problems with what you call a "coloring book" answer. That indicates that you do not want to put in the work on your side to tell us where you want additional detail. In effect, you are not sufficiently interested in seeing what a more detailed answer would be.
That attitude does not reflect well on yourself.

If you understand how mutations can spread through a population then the way they add up is obvious. It doesn't need a complex explanation because it isn't a complex idea.
If you were to put some effort in and learn what DNA is and what mutations are, then try to understand how a beneficial mutation spreads through a population then you will understand how mutations add up.
So, can you learn what DNA is?
And, can you learn what mutations are?

Your problem is explaining how a 2nd so-called beneficial mutation can happen and effect the original..then a 3rd, 4th, 5th..etc.....each increasing the firness of the trend that is evolving.
rossum

Which additional details? I posted a spreadsheet showing the effect of natural selection, but you dismissed that. If you don't tell us what you want then we can't show it to you.
Tell us exactly what you want to see, in specific terms, not general terms. Yes, you will need to do that work.

It is evo disinformation/desperation to demand that evolution is not linked to and doesn't need abiogenesis. If abiogenesis had not occurred, what would there have been to evolve on planet earth? NOTHING! Assuming that abiogenesis had occurred, would not evolution have had to kick in with the first proto life form in order for it to eventually become a living organism? Where does abiogenesis end and evolution begin? Oh, I forgot, there's no link between the two, is there.

Ah. That is something specific that we can answer.
We start with a single beneficial mutations. Natural selection will spread that beneficial mutation through the population. For example, about one third of the human population have a beneficial mutation for lactase persistence. That is the target to aim at: the one third who have inherited that first beneficial mutation through natural selection. Note that I am not picking a beneficial mutation that 100% of the human population has inherited, like the genes to form our large brains.
So, some numbers. The average human has about 75 mutations. Our population is 7 billion (7e9) so in the whole population there are 75 x 7e9 = 5.25e11 mutation in total. There are 3e9 base pairs in the human genome, and for each base pair there are 3 possible point mutations, from the current value to any one of the other three values. This gives a total of 3 x 3e9 = 9e9 possible point mutations in the genome. Doing the division gives 5.25e11 / 9e9 = 58. Every possible point mutation happens 58 times in the human population on average.
Now two thirds of the population do not have the lactase persistence mutation, so we only need to deal with the one third that do have it: 58 / 3 = 19 copies of every point mutation. How many of these are going to impact the action of the same gene? A gene coding for 100 amino acids has 300 base pairs. So, over the whole human population 300 x 19 = 5700 mutation will affect that same gene.
The majority of mutations are neutral, so not affecting the operation of the gene in any way. The majority of the rest are deleterious. We can allow, say, 1% of mutations to the gene to be beneficial. 1% of 5700 = 57. At 0.5% beneficial that would be 28 individuals with two beneficial mutations.
So, in the human population as a whole, 57 (or perhaps 28) people have both the first beneficial lactase persistence mutation, and also a second beneficial mutation to the same gene. Being beneficial, that combination of two mutations will spread through the population by natural selection.
In every generation there will be mutations in all of the genome, somewhere in the population. The proportion of beneficial mutations will vary; the faster the environment is changing the more opportunities there are for beneficial mutations, and all possible point mutations are being tried somewhere. Fundamentally this is a result of population size, which is why species with small populations find it difficult to adapt to changing environments. They lack the necessary genetic variation to acquire enough beneficial mutations to adjust to fit the changing environment.
That was not a "coloring book" answer. I will be interested to see how you respond to it.

Unless you accept what Darwin wrote:
There is grandeur in this view of life, with its several powers, having been originally breathed by the Creator into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being evolved. (emphasis added)
There is no problem with evolution if it could be shown that some deity created the first life on earth, and then let it evolve. Darwin called his book "On the Origin of Species", not "On the Origin of Life".

A question from a lurker…if 99% of non-neutral mutations are harmful, then don’t we have a 99% greater opportunity for harm than beneficial and would not these negative mutations have a negative impact on the 1% positive, greatly hampering if not destroying any the advancements that the positive mutations may have caused? In other words, there is a 99% greater chance that mutations would destroy the human race before the 1% could gain enough to traction to advance the race.

May spread. Not will spread.
Lactose toleration is about a gene not turning off.
Of the 75 mutations how many will you consider as beneficial? 25?
Example rejected...beneficial mutations are not mentioned. Many of those mutations... 99%... would be harmful or some what harmful where the person survives and reproduces introducing this harmful result into their offspring which over millions of years might spread through the population.
Sounds like you're prescribing death.
Of course you never did mention how many are beneficial.
So you finally presented a number...1%....as beneficial. Problem is you made up that number. Why not 0.000,000,001%
Another problem....assuming there was a second beneficial mutation. How long before it spreads to the population?
Your numbers drop from 7 billion down to 1.
Once again population size creates another problem for you as the number of people with the 2nd beneficial is 1. Your population has now become local to the beneficial mutation and the 7 billion people number can't be used.
Your reply didn't use a real number but rather a made up number of 1%. Your post fails because you used made up numbers. As I said above...Why not use 0.000,000,001% as a beneficial mutation rate?

A harmful mutation damages the individual who has it, weakening its chances of passing on its genes, including the harmful mutation, to the next generation. Those individuals who do inherit the harmful mutation are similarly handicapped. The harmful mutation will quickly disappear from the population simply because any individual who has it will be less successful in passing it on. On the other hand, beneficial mutations give more success in breeding, are more likely to pass on and increase in the population.
Think of a relay race with 100 competitors. One has a regular baton, representing the beneficial gene. All the others have, instead of a baton, a live hagfish. There may be more of them, but my money is on the regular baton being the only runner left after a few changes. Of course, hundreds of new competitors join the race at each change over, most of them carrying hagfish. Despite this, over time the proportion of runners with regular batons increases while the hagfish keep getting eliminated.
Does that help? Great to hear from a lurker by the way. You should post here more often. We can do with new runners, whatever kind of baton they are carrying.
