Super Genome the Sequel?
Is this another hunt for the super genome? I thought we put that absurdity to bed long ago?
We have come a long way in a fairly short period of time in sequencing various genomes. There are grape and cow and human and ancient human and neanderthal and bee and chimp genome sequencing projects and one factor has become pretty much a universal characteristic and that is that the genomes can be identified.
Send a lab an unknown sample and they send back a short note saying "That's a goat." or "That's a human." or "That's a elm tree".
We have samples from ancient folk and modern folk, from here and from there.
Novel features evolve over time in populations by changes in the genome that then get filtered by natural selection.
It all comes down to imperfect copies.

Re: Super Genome the Sequel?
If the genome of a daughter is different than the parent, isn't that sufficient evidence?

Re: Super Genome the Sequel?
In the example of the doggies the daughter population showed a trait that had not been in the parent population, namely webbed feet.

Re: Super Genome the Sequel?
HUH?
How do we know that the genes for webbed feet were in the parent doggie population?

Re: Super Genome the Sequel?
And that too was covered in the example.
The webbed feet were inheritable.
If a Creationist does not want to accept the fact of Evolution, then evidence will seldom sway them.
Those that do honestly look at the evidence though soon abandon Creationism; and that is what drives the avoidance schools, the avoidance textbooks, the avoidance radio and TV networks, the avoidance browsers ...

Re: Super Genome the Sequel?
But today we can identify not just individual species from a DNA sample, but often specific populations within a species.
That shows that genomes do change over time.

Re: Super Genome the Sequel?
Actually, you are wrong on all counts.
It's obvious that you are clueless what a detrimental mutation is if you think that webbed feet in this case was one.
And I also explained the method that led to the mutation becoming fixed in terms an eight year old could understand.
Since the full explanation was in Message 51 over in the first thread I'll repeat it for you here.
quote:
Let me give this a try.
There is a population of doggies.
The doggies have puppies.
A few of the puppies are not perfect copies.
Those puppies have webbed feet.
The other puppies think they look funny and call them names.
The environment changes; water levels rise.
The puppies with webbed feet were happy; they played and swam and all hung out together while they laughed at the puppies without webbed feet that couldn't swim real fast all the way from here to there and all the way back again.
The puppies without webbed feet moved to higher ground and they played chase and catch the tail and run around the tree and laughed at the puppies with webbed feet.
Soon there were two different populations, the clean foot puppies and the web foot puppies.
And that is how evolution works.
The two populations developed through sexual selection; the clean-foot puppies laughed at the web-foot puppies and the web-foot puppies knew that clean foot puppies had cooties.
It really is that simple.
The process is the same regardless of the number of such events. Homo sapiens is still just a Primate.

the mutation comes first.
Natural selection always operates after the fact, it never causes any change.

How novel features evolve
There is a population of mice.
The mice have baby mice.
Not all the copies are perfect, some have mutations.
Some baby mice are tan.
Some baby mice are dark gray.
Some baby mice are bright pink with yellow and green stripes.
The baby mice that are tan go out to eat and play. Those that stay on the tan rocks find lots of food and have fun playing. They grow up and marry the mouse next door and have lots of pretty tan baby mice.
Those that play on the dark gray rock though get eaten by predators and don't get to play or have fun or grow up to marry the mouse next door and have lots of pretty tan baby mice.
The baby mice that are dark gray go out to eat and play. Those that stay on the dark gray rocks find lots of food and have fun playing. They grow up and marry the mouse next door and have lots of pretty dark gray baby mice.
Those that play on the tan rock though get eaten by predators and don't get to play or have fun or grow up to marry the mouse next door and have lots of pretty dark gray baby mice.
The baby mice that are bright pink with yellow and green stripes go out to eat and play. They get eaten.
Soon there are two populations of mice, tan mice and dark gray mice and bad little mice are told, "If you do that again you will turn pink with yellow and green stripes and get eaten! And it will make you go blind too!".

listen..hear that woosh?
That's folk telling you the same thing yet again.
If natural selection is the main mechanism of causation, there has to be a molecular interface between the resulting gene and environmental pressure.
Natural selection always operates after the fact, it never causes any change.
See Message 55.

Re: listen..hear that woosh?
Whoooooosh
The mice do not turn tan or turn dark gray.
Let's try this again but slowly.
There is a population of mice.
The mice have baby mice.
Not all the copies are perfect, some have mutations.
Do you understand that?

Remember that it really doesn't matter which came first.
Mistakes happen.
Mutations continue.
Pick a population and there will still be mutations.

a second factor
A second factor to consider is that those folk doing genetic modification of plants make their money by selling seeds and stock each year. One way they do that is by making sure that the plants will not reproduce.
