The human body Is crazy awesome. I wonder what benefits “perfect” conditions could offer to human development?
Under the perfect conditions, one would assume a perfect could be made. But that's the trouble, trying to determine what these perfect conditions are. Or if they are morally correct to enact.

There really is no such thing, even traits that we often consider disorders such as ADHD or being in the Autism spectrum can lead to increased fitness under the right evolutionary pressures.

I'm not sure genes work that way. It is no longer a natural selection process; those genes won't be weened out quite like hundreds of years ago. The only way I see it as possible would be to also introduce gene correction - and religious folks don't like people playing God.
Edited: And yes, environment plays a role in development as previously pointed out.
I guess the God fearing folks don't like the idea of playing God. It's only a matter of time before a culture or country starts correcting genes to create a more well rounded diseaseless as possible people. Anyone think China isn't already on top of this? It's already been done before, rogue scientist or not (HIV immune twins). Yeah they have a decreased lifespan of 20%, but the proof is there. If CRISPR mutates inert genes though, that could prove problematic in the future evolution of humans.
ADHD can be caused by a pregnant woman living in a loud environment with very few quiet moments. Something about the noise during the first trimester changes the way the fetus develops.

Sure...and your source?
There's a lot of randomness involved.
Perfect conditions should indicate no mutation is necessary. I believe pressure makes diamonds.
There's pretty solid evidence that even under perfect conditions people won't live past ~120. There's so many people on earth that you'd expect to see pretty much every outlier occur, and yet only one person ever cracked 120 (died at 122 I believe) and nearly all other ultra long lives have died in the 1-teens. So that's one area that we roughly know.
If perfect people mate with perfect people, inevitably mutations will arise that lengthen lifespan, and then continue with that perfect on perfect and you’ll increase human longevity.
In the past those with short lifespans were less likely to mate, so in all likelihood only those with longer lifespans mated.
Now, there’s no need / external pressure to live longer.

Humans can have kids at like 12-13. Living to 50+ for men might mean more kids if you can keep finding mates. You will be competing with younger healthier males for those mates. You also have to factor in that a LOT more men died from violence in the past. Hunting, farming, and war tend to reduce the male population a ton.
Women tended tomdie in child birth of those first kid a lot more in the past. They also can't really have kids past their late 40s. Living longer won't change that.
Her name was Jeanne Calment. She died at 122.
She stopped smoking in her 90s when she went into a nursing home. Then she decided it was silly to stop because she enjoyed it so, she started again. Stop doing things you enjoy and you may as well pack it in.
You probably missed that part...or maybe they left it out. Moderation in all things.
Almost like proper nutrition is important for growing humans or anything for that matter.
