Types of genes?
What are the different types of genes?
What does "types of genes" mean?

Re: Types of genes?
Do you agree that the latest common ancestor for all plants and animals had more types of genes than plants and animals today?
Sure, I'll agree.
If so, then don't we see the opposite of ND; rather than a slow accumulation of genes via mutation and natural selection
Not neccessarily.
Assuming, by going from the latest common ancester to animals and plants, the population loses a bunch of types of genes (to specialize into either plant or animal). If, after of slow accumulation of new genes (through RM and NS), new species of either/both animals and plants emerge, then everything is hunky-dorey. Evolution has occured like the discription in the ToE, AND, the latest common ancestor had more types of genes.
Just because genes were lost at some point in the past doesn't mean that they must continue to be lost and that no new ones can come about. If a WHOLE LOT of gene types were lost from when the latest common ancestors specialized into plant and animal, then plants and animals would have a lot of room to evolve new genes before they exceeded the original number of types of genes.
They don't however, as you seem to be assuming, have to continue to lose more and more gene types all the while never evolving a new one.

Re: Types of genes?
This is not some bump in the road but a general pattern and it conflicts completely with the ND hypothesis on evolution.
But I just explained how that is not neccessarily the case.
There is not a slow accumulation of genes via random mutation and natural selection, at least not for the bulk of plants and animals.
Non sequitor.
There could still be slow accumulation of genes, even if the latest common ancestor of plants and animals had more types of genes if the specialization into either plant of animal cause a loss of a lot of types of genes. Because then the specialized plant or animal could slowly accumulate genes after that while still being below the original amount.
So when people observe microevolution, they are not observing the process that evolved the design of organisms, their genes.
Well now you're just taking it and running with it

Re: hmm....
I wrote this last night but the board was down.
You've already moved past it but I'll post it anyways.

Does it predict similar genetic sequences for similar traits between marsupials and placentals that are considered by evos to have arisen via convergent evolution?
Or is it expected that the "random mutation" process should generate different genetic sequences producing those similar traits?
Random mutation generates the different genetic sequences that produce those similiar traits that have arisen via convergent evolution, but they could still be similiar in sequence(the order of the nucleotides) as those sequences of genes are producing similiar traits. I'd expect different sequences that produce similiar traits to have some similarities in their sequence(the order of the nucleotides) as that order is what produces the trait. If the traits are similiar then the order should be similiar. But they could still be different genetic sequences.
That seems confusing because the word "sequence" is being used with different meanings

Re: Types of genes?
Nice thread necromancy...
But seriously, this was from 1.5 years ago. The guy I was respnding to is suspended. And, he explanined what he meant in Message 10.
