Faith writes: Mutations hardly ever change anything in the phenotype and when they do it is usually a disease. Diseases will be removed by natural selection, so that is a moot point. The mutations that do change phenotype and are beneficial will be passed on at a higher rate and can spread through the population.

They're either humans God made as humans or they are something else God made to be something else.

So she was practicing.
Didn't help. Eschew obfuscation. Habituate elucidation.

Diseases will be removed by natural selection, so that is a moot point. Again there are a lot of genetic diseases, a list of thousands I believe, that obviously didn't get removed.
The mutations that do change phenotype and are beneficial will be passed on at a higher rate and can spread through the population. And as I understand this there are so few that fit this description the number is really negligible. And there is no reason to think they'd be passed on anyway unless they do something that gets selected but there is no reason to expect that. They may be "beneficial" only in the sense of doing nothing in particular but not causing harm. For instance the folded or "curled" cat ear. There is no reason to think it would have been passed on in the normal course of things. It only got established because people went to great lengths to make sure it got passed on. Edited by Faith, : No reason given.

And as I understand this there are so few that fit this description the number is really negligible. So the physical differences between humans and chimps comes down to a negligible few genetic differences? Are there just 5 or 6 genetic differences between chimps and humans that are responsible for all of our physical differences?

It’s worth pointing out that most genetic diseases are rare recessive genes which are hard for selection to completely remove - but selection does keep them rare.
Some also have advantages that outweigh the problems e.g. being heterozygous for sickle-cell gives very little disadvantage, but helps resist malaria. Edited by PaulK, : No reason given.

Faith writes: They're either humans God made as humans or they are something else God made to be something else. Important to make your mind up I think. Seems a bit of a waste to me. But not much time to have the lot of them all running around together. Only one made it to the ark too. Je suis Charlie. Je suis Ahmed. Je suis Juif. Je suis Parisien. I am Mancunian. I am Brum.

They either died in the Flood, which I guess they did since they are fossils, or they are descended from one of the three couples on the ark.

Wouldn't it make more sense to put them before the flood? Wiped out by the flood? Eight human beings made it to the ark, three couples capable of reproducing, and any of those on your list that are true humans came from those three couples.And our geese will blot out the sun.

Since humans are not descended from any ape at all there is no connection whatever between the genomes.
Fortunately those thousands of diseases are rare, yes. So far.

Yes I realized that after I wrote what you quoted and changed the post.

Faith writes: Since humans are not descended from any ape at all there is no connection whatever between the genomes. There is a connection. It's the 98% of the DNA sequences that is the same. For the purposes of what I am asking you, it doesn't matter if this is a result of common descent or creation because DNA acts the same no matter how it got there. You are saying that if a base is changed, whether by a mutation or by a creator, that it will either be neutral or deleterious, and we can ignore any beneficial changes because those are few if any. If this is true, then we have to ask how a creator can create two separate genomes that differ by 40 million differences while sharing 98% of the rest and not have this result in millions of diseases. Also, how can this result in any beneficial differences between the species if differences cause so many diseases, according to you? Even if we assume creation, what you are saying can't be true.

If chimps have somewhere around 95-98% human DNA, how much do you think, say, Homo habilis had?Je suis Charlie. Je suis Ahmed. Je suis Juif. Je suis Parisien. I am Mancunian. I am Brum.
