How is it beneficial?

Smaller target for other humans who've been hurling deadly projectiles for 40,000+ (or however long) years?

Yabut, risk of starvation because can't reach the top shelf in the larder. Weeping

RE: Beneficial mutations
This might seem kind of silly but the actress, Elizabeth Taylor was born with a mutation called distichiasis, which is a double row of eyelashes.

http://bodyodd.nbcnews.com/_news/2011/03...c-mutation



Some people have the extra row right next to the eye ball area and it irritates their eyes to the point that they have to have the lashes removed surgically, however Elizabeth Taylor's extra lashes were above the regular lash line giving her thick, luscious lashes without the irritation. She also had blue violet eyes. An amazing combination of mutations which created, well.....stunning beauty.

Unfortunately, none of her children inherited this mutation, which most women would consider quite beneficial.

Maybe this would keep the sun out of the eyes, just enough to prevent cataracts.

Shakespeare's Comedy of Errors.... on Donald J. Trump:

He is deformed, crooked, old, and sere,
Ill-fac’d, worse bodied, shapeless every where;
Vicious, ungentle, foolish, blunt, unkind,
Stigmatical in making, worse in mind.

Good point if by not killing us you mean not compromising our survival in any way. They are beneficial because they open up the search space and add information to the gene pool. This means that the mutation might not be beneficial when it first appears but it could be in the future given another mutation or being matched with the right combination of genes.

With artificial evolution, a population will lose information over time if all you have is crossover and even without a selection pressure it will still converge upon a single solution. You need to apply mutation in order to counteract this.

First is a claim that we have fossils for 90% of non-avian land vertebrate lines currently living and thus fossils are not rare.

Ask for a citation for that because I seriously doubt that it is true.

And even if it is true, it's utterly meaningless.

We have a lot more "fossils" of humans who lived in the last two hundred years than we do of humans who lived two thousand years ago. I'm not impressed that we can find fossils of "recent" creatures.

The problem is, as soon as you find a missing link to show this guy, he'll declare it a "final form" and demand you find two more missing links. OddGamer, I suggest dropping the discussion with this guy. He won't approach it honestly, and it will only end in tears.
